### Human: Protection for external brake resistor Hi guys! We have problems with 755 drive's brake resistor: one terminal was grounded by loose metal clamp, resulting in IGBT blowup... My question is ¿What is the apropiate protection to drive? I don't find rockwell's recomendation to this. ### Assistant: For externally mounted braking resistors, the recommendation is to protect the drive from resistor temperature rise. This is done typically by a normally closed contact from an internal thermostat in the resistor. This signal is often used to open a contactor upstream the drive and remove the supply. However, the protection above will not be able to detect the failure of the internal breaking IGBT on a PowerFlex 755 drive. That type of IGBT failure may require fast DC bus branch short circuit protection. A possible way maybe the use of an external breaking chopper (or DBU - Dynamic Breaking Unit) and use an appropriate fast fuse to open the DC bus circuit and protect the IGBT inside the DBU. More information and general guidance about this is discussed on https://literature.rockwellautomation.com/idc/groups/literature/documents/um/akdbu-um001_-en-p.pdf Please, also note that for High Horse Power PowerFlex 755 (frame 8 and above) the only way to use an external braking resistor is with an additional breaking chopper (since those frames do not have the internal breaking IGBT). For frames 1 to 5, the breaking IGBT comes a standard and from frames 6 and 7 is optional. Thanks. \\n


### Human: Using MRP instruction over a Master axis followed for slave using MAG with Master Reference command Hi everyone, Right now there is a system with a Virtual Master Axis defined in meters, it is moved using MAJ. This master is guiding a winder defined in meters using a MAG with a fix gear value and the winder is guiding a spindle defined in degrees moved by MAG with Master reference Command and ratio variating according to the diameter of accumulated material in the spindle. This MAG is continuosly updated using a XIO condition of the MAG EN bit just before the MAG instruction. What I'm trying to do is use a MRP instruction to update the winder position to 0 when a splice has ocurred and it's starting the wind in a new shaft. I want to know if doing this I can cause any instruction fault on the current MAG with Master reference command or what other consideration should I have into account?. Thanks in advance ### Assistant: Hello Nelson Can I rephase what you are doing to make sure that I got it correct? You have a Winder that is geared to a virtual Master with a fixed ration. On this winder you have geared a spindel with a variable ration. And you would like to do a MRP on the Winder at a specific event. If the above is correct, this is possible without generating any MAG instruction fault on the Winder or Spindel. All axis stays geared with the same ration. you can run the MRP absolute or relative mode on the Actual or command position. That will only affect the Position counter of winder not his motion. What could be affected is if some equipment's are dependent of the position of the Winder. but apparently in you case it is not. I hope that help. regards \\n


### Human: 6 Axis Robot Control Hi, I am hoping that someone can point me in the right direction in terms of hardware selection. What would be the minimal family range that can communicate to a 6 axis robot, Compact Logix, Compact GuardLogix, Control Logix or Control GuardLogix? ### Assistant: Welcome to Engage! Strictly looking at the number of axes to be controlled, I would say a CompactLogix Controller can do the job. You can start to read about available features in the CompactLogix Selection Guide There are a number of things to discuss beyond that, so it would be better for you to get in touch with a local Rockwell Automation representative. fuzzy logic Please don't forget to LIKE and highlight the decisive answer: REPLY > Make Best Answer \\n


### Human: Upload Parameter from Kinetix 350 Hello every body. We have 5 kinetix 350 servo drive which have connected to 1769-L33ERM CPU in our machine . I want to back up program from PLC and Servo drive. If I upload program of PLC , are there parameters of servo drives in program of PLC? ### Assistant: Hello Akbar Kinetix 350 is a CIP motion drive, so all the parameters are stored in the PLC code and loaded fat startup to the drive. So yes if you save the application code you will save all. Also if you replace a drive, you just have to set the IP adress of the drive and at startup (power on) all the parameters will be loaded automatically from the Controller (PLC) via ethernet IP cip Motion to the drive.

### Human: Loadcell feedback to a Kinetix 5700 drive Hello all, Keeping it simple, I am running a servo to a force. I have a loadcell to an Analog input card that feeds MCD instruction to control a MAJ velocity. This works, but I am thinking that a could wire the loadcell directly to the secondary feedback of the K5700 and just use a MAM with the loadcell target? Dose anyone do this. This there any information to help me. My (current) loadcell provides -10/+10 3 wire. ### Assistant: Morley, Here is a discussion about force and torque. https://engage.rockwellautomation.com/discussion/constant-force-torque-application \\n


### Human: Powerflex 755 with PM motor - Effects if moise in encoder feedback readings Hi everyone For a PowerFlex 755 with PM motor with incremental encoder. If we have noise and/or encoder inaccuracies that affect encoder feedback over time will this jeopardize motor commutation over time? On the first start after a power cycle, we do the PM Offset test and the relationship between that angle and encoder feedback is good, so we have proper motor commutation. But eventually if the encoder feedback is not accurate for any reason over time, will we loose that relationship between the commutation angle and the encoder feedback? Will we lose proper commutation of the motor over time? Can this cause Overvoltage faults? What other effects cuald affect having this issue with the feedback? Thanks in advance ### Assistant: Hi, Check your encoder cabling route, it must be far away enough from AC power cable. Check with OSC on your encoder square wave output , to ensure encoder can send correct output signal. Terence \\n


### Human: Changing encoder in a HPK-B1613C-SA42AA I am in the process of changing the SICK SFS60-HPZT4S01 encoder inside our HPK-B1613C-SA42AA servo motor. The encoder not only tells the drive how fast the motor is spinning, but it also tells the drive the specs of the motor. SICK says they don't preprogram the encoders, and I would need to get the EPROM from Allen Bradley in order to download it to the new encoder. My question is, is it possible to get the EPROM from them? ### Assistant: EDIT: linkified for convenience -FL Hi Jonathan, I'm not sure if this can answer your question but I'm seeing that Rockwell sells the complete Replecement kit for HPK series motors and provides the installation instructions. https://literature.rockwellautomation.com/idc/groups/literature/documents/in/hpk-in002_-en-p.pdf \\n


### Human: PM Offset test in load sharing configuration between Permanent Magnet motors Hi everyone. We have a load sharing configuration betweeen 2 permanent magnet motros coupled to the same shaft and with only one encoder signal for both. My question is how can prevent or configure sequentially the drives to perform the Auto PM Offset test after a power cycle?. So it's clear that the drives needs to perfomr this test after every power cycle but how can we prevent the drives doing the test at the same time? Thanks in advance ### Assistant: Hello Nelson. could you give more details about the equipment that you are using. provide the Motor type and encoder type, the drive and controller. this way we can identify. If you use a complete system with Rockwell Automation equipment, you should not have to run the offset test. if some HW are not Rockell them it's a different story... and we need details. regards \\n

Thanks in advance ### Assistant: Hi, From the help tab in studio 5000 The Faults & Alarms page displays the current status of faults and alarms log structures currently in the controller for this axis. The display is read-only except for the ability to clear logs independently. don't think it is possible I am afraid. \\n


### Human: kinetix 5500 duplicated IP adress fault Hi, i Have a kinetix 5500 drive and it stop and show a message  duplicated IP address in the manual this fault is a major fault, i try to change or another IP address but the fault still happening, the servo drive is faulted any time when is active and when the control is off, to reset the fault i turn the power off and turn on again and it reset the fault but it fault again in no longer time, i try changing the ethernet cable, and changing the ethernet port in the switch, i read the manual but in the troubleshoot chapter I can't find any other different solution but change the IP address. i hope if any knows another possible solution or if its require to change the device for a new one. regards and thanks. ### Assistant: Hi Tony Could you give the Error number please, that could help. If you see a duplicated address, double check all your installation IP address. Check that your subnet mask is correct aswell. Do you use a Kinetix 5500 ERS2 ? if yes are you using a networked safety. did you Reset the Safety ownership ? Regards \\n

### Human: STO during deceleration EDIT: moved to Drives and Motion community -FL I have some servos on K5700 drives. The STO get broke with a light curtain block. This works fine during the move, the servo stops and restarts with an opto, but if the light curtain gets blocked during deceleration the drive keeps going and actually overshoots the target. Has anyone else seen this? There is no brake, but the servo is under load and should want to stop. ### Assistant: Hello Morley, couple of questions for you: What Kinetix 5700 are you using ERS3 or ERS4 ? Are you using a wired safety signal to the drive or a CIP Safety over EtherneIP ? When you operate an STO on a Servo drive you stop the motor control. So if you request a safety stop action that directly does an STO on the drive , the motor will coast without any control whatever the movement you were doing. This is called a stop category 0. So this is normal that you can overshoot a target since no more control is applied to the motor. With the Mechanical and load inertia the motor can rotate freely for a certain time if you don't have a safety brake. Now you can deploy a different safe stop category. Safe Stop category 1 , called also SS1 . Now the SS1 will give you time to decelerate correctly your axis and stop if before STO occurs. The way of deploying this feature will depend of the answers you will provide on the previous questions. you can also look at this manual : Kinetix 5700 Safe Monitor Functions Safety Reference Manual (rockwellautomation.com) (Link updated) regards \\n


### Human: Powerflex 755 Speed Trim Follower Hi everyone, actually I have the following drive configuration: There are 2 Permanent Magnet motors driving the anvil roll – one on the drive side and one on the non-drive side. The motors are sized at 76.28 kW each (152.56 kW combined). Each anvil motor is controlled by a 302 Amp PowerFlex755 drive – three phase 480VAC fed. Each drive has a 5.3 ohm 22kW dynamic braking resistor connected to it. Only one motor has an encoder on it – the drive side motor (master). The feedback from this encoder goes to the drive panel on the 3rd floor and is split to 2 signal converters. The signal converters output are wired to each drive's Dual Encoder module. The drive side roll runs in Speed Regulation mode with a speed reference passed from the machine Webformer section. The non-drive side roll runs in Torque Regulation with Torque Reference Setpoint set by the drive side Limited Torque Reference feedback. I would like to know the list of parameters to change and the required wiring (if required) to change this configuration to Speed Trim Follower because what we are seeing is that normally one of the drives is managing the major part of the torque so the load sharing system is not working properly. I need to know in detail about the parameters for passing the current Master torque to slave and the required for the slave to compare this value with its current torque and use the error to apply the speed trim. I hope this explanation is clear and thanks in advantage. ### Assistant: EDIT: removed external formatting -FL Hello, there is some conceptual guidance on how to apply a Speed Trim Follower scheme with AC drives via the following document: https://literature.rockwellautomation.com/idc/groups/literature/documents/wp/drives-wp001_-en-p.pdf This other technote includes a document that goes a bit further highlighting the challenges ahead based on the block diagram of a PowerFlex 700VC drive. There is mention of the Process PI Trim to be required to accomplish this scheme. https://rockwellautomation.custhelp.com/app/answers/answer_view/a_id/516124 I think the way forward would be to understand how this is done on the PF700VC and try to extrapolate or correlate those key block path diagrams from the PF700VC to the ones in the PowerFlex 755. The Reference Manual for the PF755 includes some detailed information at block diagram level as well. https://literature.rockwellautomation.com/idc/groups/literature/documents/rm/750-rm002_-en-p.pdf The other challenge, once the key parameters are identified will be to pass that information from the master drive to the follower(s), possibly by mapping those key parameters to analogue signals and wiring those accordingly. I am leaving an open door here to see if there is anyone on this audience that may have used this concept within a real drive system application and would like to add some advice on what could be a challenging, but very interesting application. \\n


### Human: Powerflex 753 speed ramping with Digital Input Hi I am having a PF753 drive with Digital I/O control . Now we need to set the drive to work in following way . When start command is given the drive will run at a minimum speed . When a digital input from selector switch is given then the speed should be ramp up by certain percentage . say for e.g if the start speed is 10hz , when the input is given then it will run at 11hz , and when second time the input comes to drive the drive should run at 12hz , in this way the speed needs to ramp up every time input comes.

### Human: Kinetix5100 Micro LC50 Hi Everyone 1st time posting here. I have a Kineti5100, MicroLC50 and downloaded software provided by Rockwell, example code. Dynamic Position Move, using the C_RA_K5100_Index_CmdSts_V2.2 Everything works just fine except for one thing. After issuing a STO function and then resetting the safety. The C_RA_K5100_Index_CmdSts_V2.2 will not reset the STO fault. It will reset all other faults but not this one. I have used the same drive with Compact Logix and that UDFB will clear the STO. Any guidance on resolving this would be appreciated. Thanks, Dennis ### Assistant: Hello, I have the same problem. I found in the release notes of firmware 1.2, that this fail was fixed in that version, I try updating but stopped working some parts of the PLC-K5100 communication. Try version 2, 3 and 4, same problem (no communicaction). My next step is to change PLC to micro 850 new generation, as it accepts class 1 ethernet ip with new instructions similar to CIP MOTION.

### Human: PowerFlex 70 (400V, 60A, 30KW) not delivering more than 15A Current Output Hi, I'm using a PowerFlex 70 (400V, 60A, 30KW) connected to the Primary of a step up transformer (20:1) and having the secondary of the transformer connected to a stator (automotive EV motor that has no rotor fitted, so there's no resolver to give the speed input). This is used only to be able to rapidly heat the stator windings of the motor due to the huge current they are subjected to. The PowerFlex70 is set up to operate in Open Loop, using the following parameters: p40 Motor Type: Induction p41 Motor NP Volts: 400 p42 Motor NP FLA: 30.0A p43 Motor NP Hertz: 50.0Hz p44 Motor NP RPM: 1480RPM (I put a fake motor speed as I don't know how to approximate what speed would have an electric motor with the same characteristics) p45 Motor NP Power: 22kW It accelerates to 50Hz and works well up to 15A current output, but I wasn't able to get it to 30A that I need on the output, which the transformer will convert to 600A on the stator windings. I am using p196 Param Access Lvl as Advanced and I couldn't figure out why this 60A drive gets limited to 15A output. Please help me with some advice to unlock its full capacity. Thank you! ### Assistant: Iordanoiu Look at the Block Diagrams... I'm guessing you are V/Hz mode. The output current depends upon the load. PFlex-RM01 \\n


### Human: Fault Kinetix 6500 Hello my friends. I have a problem and I hope you can help me. Why does a Servodrive remain in Stand by status? and it cannot be corrected, the only way is to turn off the entire machine (including PLC) and only then will the servo drive return to its Running working state. And it is not just 1 servo drive, it is random, it should be noted that the machine has 120 servo drives controlled by 2 L73 processors and 2 1756-EN3TR modules. And this happens when we turn off a drive rail for various reasons, after cleaning, changing a servo drive, etc., and when we reconnect the control power of that rail, there is 1 servo drive (it can be any) that starts in the STAND state. BY and it is impossible to return it to its working state and the only way is turning off the whole machine or the PLC. It should also be noted that it does not always happen, there are times when it starts up fine, but when it happens, a lot of time is lost to make the machine operational again. The ethernet communication is also correct, since I PING the IP of the drive in STAND BY, and it is correct. I have to point out that the 1756-L73/B PLCs have fw 21.011, the 1756-EN3TR/B modules have fw 10.010, and the Kinetix 6500 servo drives have fw 3.003. Thanks so much. ### Assistant: Hello GAAM With a large servo drive architecture like yours it is hard to identify the source issue without being on site. Because there are a number of things that can go wrong in a large system if not correctly managed. Basically, the standby issue means that the drive is waiting to receive configuration data from the controller. it is a communication issue at startup, So we have 4 possible sources of this communication problem, the controller, the ethernet Card, the switch or the drive. 1st : What is the Logix Version , and Drives FW used in your system? 2nd: Does this issue as always exist? or is that recent? have you made any changes on this machine (new HW, network changes...etc)? 3rd: Connect with Studio 5000 and check the standby drives information's and status, look also at the extended fault information's. look at the fault history to see if there is not multiple faults cascaded. 4th: What is the CUP (Coarse Update Period) of the Motion Groupe. 5th: does the issue occurs only on a specific group of axes associated to one of the EN3TR ? 6th: Where Time Grand Master is located (EN3TR's or Controller or somewhere else ?) 7th: What switch are you using? 8th: When you turn off the Drives Power supply control. Does that power off the switch aswell ? Thanks for the feedback Regards \\n


### Human: Questions regarding the MAPC master lock position and cam lock position Hi, I'm setting up a motion axis with MAPC motion instruction. We are programming a derrick crane's main boom hoist axis to maintain a constant horizontal movement speed. The virtual/master axis is the boom reach radius, and the physical/slave axis is the boom hoist motor. The picture below illustrates what the setup looks like. I have run a couple of tests to see how it works, but the motion axis seems to be struggling to follow the actual cam profile I entered in the Cam Editor window. I believe the issue is my lack of understanding of the master lock position and cam lock position. I read a tech note in Rockwell's knowledge base, but I still cannot relate that to my actual setup. So any insight would be greatly appreciated. Other parameters are the start slope and end slope in the cam editor window. What is the purpose of these two parameters? how do they impact the cam profile? Thanks! ### Assistant: EDIT: linkified for convenience -FL Zhang, The key to making this work is have a CAM... which is the relationship between the input/output which are unitless. When you get into xy or polar, then you might look at translation of coordinate systems. Logix has some built-in translations for coordinate systems... This one might work for your application where J3 is always vertical. Prior these defined geometries we would just write the vector loop equations. This is typically two equations with 2 unknowns so you can create a substitution and solve for the position equation in terms of the input (actuator).

### Human: PF 753 voltage dependent errors Having issues and wanted to start simple... Copycat drive info and default. Then things got weird, at first I saw an illegal message with a long numeric code briefly before the hmi started to re initialize . On occasion the hmi would connect to the drive but every time pressed enter for my language selection I could go no further and the hmi started over. Eventually this turned into a stuck initilization screen if I left it powered long enough. Sometimes there would be just blank fields with no characters/ logo. A little while into this I noticed that, guaranteed, it would connect to the drive right before the bus dies when I shut the power off. Long story short, found that about 150 vdc on the bus and I get normal operation as far as the hmi goes and it doesn't keep reinitializing. What makes this odd to me is that when I changed out boards from another drive , the main board and control pod, I got the same results no matter what combo was installed. And the errors/ how it acts are dependent on what the bus voltage is. Anything over 200ish and it starts doing stuff. Couldn't find any other pple describe something similar, so any ideas? ### Assistant: First off... I'm not a drives guy... But the circuit boards get powered from the power structure so if you swapped boards and still have issues, then the problem could be the power structure (which is power the boards)? Maybe it is generating a lot of interference (do to a power component issue... e.g. smoothing capacitor, voltage regulator, etc.) \\n


### Human: PowerFlex 753 go to maximum speed Hello, I'm using a PowerFlex 753 (7.5kW, 15A) AC drive. It takes the speed reference from the analog input. It works in closed loop.

### Human: PF525 Rating Table Object? Hi all, I'm reworking an AOI I wrote for the PowerFlex 525 and am diving into the DPI objects documented in 520com-um001_-en-e.pdf. One parameter I originally put to use to establish parameter ranges is D367 [Drive Type]. I made use of QA20724 to get rated horsepower, power, current, output voltage range, input voltage, and rated current, but the code to produce this is a little involved at 140 lines. I came across a reference to a Rating Table Object in the above manual and am hoping to see if Rockwell can divulge a little more info about it and whether it provides a more straightforward way of determining these parameter ranges. I'm perfectly happy sticking to D367 if there's instead some formulaic way of determining this information. Thanks! ### Assistant: JeremyM IDK about the Rating Table Object... but based upon the text provided, I can take a guess. In the case of PF750, I know there are over 1700 parameters in the Parameter Object. When looking at a 5 HP vs 500 HP, the parameter list is identical, however, the values (min, max, default) will be different. As it turns out, only 17 of the 1700 parameters are related to the power structure. So I think this table is for those 17 parameters to show the min, max, default that would change bases upon the power structure. For example: The output current (or anything related to current) is different (in terms of min, max, default) for a 5 HP vs 500 HP. \\n


### Human: Powerflex 525 with PWM EDIT: moved to Drive and Motion Community -FL How to control Powerflex 525 with Three-phase motor by PWM or PTO ### Assistant: The PowerFlex 525 drive comes with a digital input built into the terminal block (terminal 7) able to read pulse train signals up to 100 kHz at 24V. PWM (Pulse Width Modulation) is a general term that refers to the way that most of the AC typical variable speed drives operate at the inverter section of the internal power stage. PWM technology is embedded in the hardware of the drive. The inverter section of a AC drive generates very quick voltage pulses of different length that are applied to the motor windings. The average values of those voltage pulses mimic a voltage waveform of variable frequency, which generates the motor shaft to turn. Very rarely the user/designer needs to be concerned about the PWM intrinsic feature of the drive. Apologies if am not fully understanding the question yet. Please feel free to expand or further explain the application or the task ahead to further comment. Regards, \\n

For some reason when we move the axes up or down, we will intermittently get an Inverter Overtemperature FL Fault. So far, we haven't been able to nail down a root cause. It doesn't seem like the torque is causing this problem because we have tried with varying weights and torques, and it doesn't seem like velocity or acceleration are the main factors either because we have tried playing with the speeds. We trend the inverter temp and notice that this alarm occurs when the inverter temp hits 155.6 degrees C. Does anyone have any good ideas as to why this fault might be occurring in our application? ### Assistant: EDIT: added proper numbered list to questions -FL Hello Joe. Based on the little information's that you give us it is not easy to identify the issue you have. Some questions: is it a new installation that you are commissioning or something new on an old system? you said that the dynamic generates the over temp fault. what is the torque value before the fault occurs... are you close to 100% or above for how long , does the 2 motors shows approximately the same torque level (how did you manage the load sharing ? ) have you check that the break works correctly? stupid question (but I have seen it) check if the motors are not working against each other did you monitor the drive capacity tag? could you provide the Drive and motors ref , to see if they can match? do you have a current and position error trend ? Regards \\n


### Human: Offset during dynamic gearing between virtual axes Hi Everyone , I would like to gear 2 virtual axes during either a run or before axis moves. In order to do that , I used following solutions but still got an offset when it was geared with ratio other than 1:1. 1) Using MRP Absolute to move slave axis to master's position then latch gearing. (1:1 it works but if the ratio is different , there is always big offset) 2) I calculated the actual position difference between master and slave and use this as failure to make relative move with MRP. ( I got 0.08 position difference at the end which might be ok but still not precise enough for me) ** Note : Offset happens when gearing ratio is different than 1:1. Is there any more reliable alternative to do it ? Thanks in advance. Sertac ### Assistant: Hello srtc the big advantage of virtual axis is that they are perfect (not position or velocity errors). So the issue that you have can not result of a bat tuning or mechanical setting...etc. It is certainly. a MAG setting or axes setting. could you give more details on this please ? to answer your 2 points: it is normal that if you do not have a 1:1 ration you will see a difference on your axes. are you using Ratio or Mastercount/slavecounts ? what ratio format have you selected ? are you using the clutch ? all those parameters will impact the gearing relation between your master and your slave. review the Logix 5000 Controllers Motion Instructions (rockwellautomation.com) manual (p112 to 124) to know more about those parameters. TIP: you can also use MAPC to do gearing, regards \\n


### Human: PF755 skip speed EDIT: reposted the request the OP removed after posting -FL Hello Guys , so we are currently experiencing some issues with vibration on one of our compressors. Everything looks good on the mechanical side. I was suggested by the Senior engineer to modify Skip Speed parameters. Parameter 526 [Skip Speed 1], Parameter 527 [Skip Speed 2] and Parameter 528 [Skip Speed 3]. I am not sure how this is going to help. Has someone done this before or any suggestions? Thanks ### Assistant: Martinez, as you can see I just re-posted your original request, probably you removed it because it was solved. It's not a good practice to remove a posted content. It would be nice to know if you solved it in anothor way or if you have something to suggest to other users.

### Human: PowerFlex 755TL EMC Filter Hello. I'm doing research on the EMC filter (C3) in the PowerFlex 755TL product line. In the PowerFlex 750-Series Products with TotalFORCE Control Technical Data document, the 11th letter or number indicates this in the catalog number descriptions. In case of L (in my chosen drive this part is L), it means that there is no EMC filter, but C3 compatible. What do I need to do to have an EMC filter? If you have any information on this subject, I would be happy if you share it. Kind regards, ### Assistant: Gamze L2 is C3. For C2 on frame 7, use P-code in position 11. For C2 on frame 5-6, 8-10, add the EMC accessory kit shown on p276 \\n

### Human: Kinetix 5300 Communication I have two Kinetix 5300 drives in a new machine. Connecting to a 1769-L36ERM compactlogix processor version 33. I set the software up as we have in the past for the 350 drives. Both drives have configured IP addresses in the in the range of the processor. On startup the drives show up in my controller organizer as having no problems. They never come off the 00 state on the drives. If I unplug the Ethernet cable to the drives and re-insert. The drives go through their startup sequence and reach 04 state. I can start and run the drives without errors. I have replaced the 100 foot Ethernet cable out to the drives. I have replaced that cable also with a Cat 5e cable that checks out with our blackbox cable tester. I have moved the connection from the system Ethernet switch directly to a port on the processor. I have pulled the 24V supply to the drives until the system starts up, and applied power. The only thing that makes the drives come online is pulling the Ethernet cable and re-inserting. I have two powerflex 523's on the line that have no problem attaching at startup. What am I missing? ### Assistant: Don't have a good answer as to why you're seeing this phenomenon, but you could try programatically disabling the drives in the IO tree and then re-enabling them. It would do the same thing as unplugging the cable. It sounds like there is some sort of boot process foot race and the 5300s consistently fail the race. Programatically disabling / reenabling fixes the problem (though it doesn't solve it). The snippet below shows how to do this: You use value 4 to disable, value 0 to enable. I made constant tags to help others read the logic. Instance name is the name of the drive in the IO tree (not the axis name in the motion group). We use this sort of logic to allow the motion group to initialize on boot when a drive is missing / failed. All drives must be in place and communicating with the processor at time of PLC boot; if one is missing the motion group never initializes. The logic above allows an a drive to be programatically disabled which then permits the motion group to initialize and run. \\n


### Human: Kinetix 300 drive I have a Kinetix 300 drive, I am trying to set the IP address manually and I have followed all the steps.

### Human: DC DRIVE 20P41AD250RA0NNN Hello everyone. I have problem with a new DC drive, I conencted the control power in terminal U1 V1 220 VAC , The two gren leds are light, ACT and PWR , but the HIM and 20 comm dont turn on. The drive was in our warehouse how back up. I attached picture. ### Assistant: morera, you should apply power to the control circuits (terminals U2 and V2) of the drive. See the following technote: QA31235 - PowerFlex DC: Input power and control power Here is an excerpt: In addition to the 230 VAC or 460 VAC 3-phase input power, the PowerFlex DC drive also requires 115 VAC or 230 VAC control power at terminal blocks U2 and V2. This powers the internal power supply that produces the logic levels for the regulator board and peripherals and powers the HIM.

### Human: K5300 current overlimit I have a 2198-C1020 wired 3 phase. I had some very slow motion out of control while testing. The setup is a mpl servo attached to a rack and pinion that carries the main machine back and forth. During startup, 3 or 4 times it hit the end of travel, at about 2in/s. On the last time I got an overcurrent limit fault and now I can't clear it. I tried all the reset, on/off commands, i tried cycling power, i tried a new motor. The machine didn't hit the end of travel so hard that it got stuck or did any damage, it just stopped. One mistake I made was forgetting to set the 3 phase power from single phase in Studio5000. Could this have permanently damaged the drive? It still powers on and goes through the full boot cycle to 04. Is there any saving this drive? ### Assistant: Hello pa_servo_guy, There is very limited information about this fault online. I would suggest calling into your local kinetix technical support team to assist with this and discuss best options. This link will bring you to the contact us page, fill in the required information and the correct phone number will become available. Contact us \\n


### Human: PowerFlex 70EC I want to know what is the difference between 0-60 hertz on parameter 72? How is it going to behave at different increment? ### Assistant: Lee The Break Frequency is shown on p30 It is used to change the v/f line. \\n


### Human: PowerFlex 70EC There is an issue at my work place. This is related to the pump we have and I want to know how to adjust the setting in the parameter for this issue. The pump is running off the pressure, and the pump modulates the speed to compensate with the pressure. We're running the pump in manual mode and the frequency on the VFD is 50 Hz. We also have a valve cranked 45 degree to supply the water to other area. Every time we're having a power outage it needs someone to manually reset the VFD and raise the frequency from 15 Hz to 50 Hz. If we're running the VFD in auto mode when there is a power outage the VFD will stay on at 15 Hz the whole time. I want to know how to adjust the 15 Hz to 50 Hz in auto mode and not having somebody to reset the drive manually from 15 Hz to 50 Hz. Any suggestion in this scenario? ### Assistant: Hi Lee, I replied in another your other thread. Thanks \\n


### Human: How to Access MAH Parameter Tags How to I access the Parameter tags so I can ajust the HomeOffset from my HMI? I can't find them in the Monitor or Edit tag editors. ### Assistant: Hi JEK, I show that you are using a switch to set the home position. I am not sure how to set an offset, if you are searching a physical position to set the bit: AxisTag.AxisHomedStatus. When you have got this bit, that it means that the physical position is reached. You can add an offset to all your movements setting a MRP instruction (motion redefine position). The page 135 explains how to use MRP: Logix 5000 Controllers Motion Instructions. Reference Manual.

### Human: PF525: load reduction (e.g. via RPM reduction) when the load is about to exceed the set overload limit. P033 is set as overload current limiet. If P033 < actual current (b003) the motor is stopped and an alarm is raised. When the motor is stopped and alarm is raised seems to be a timer based on the difference between P033 & B003. The bigger the difference the sooner the motor stops. There is no reduction in RPM (b005) resulting in a lower load óf a reduction in load (b003) resulting in a lower RPM, If b003 =2.4Amps and P033=1 Amp, the motor stops instantly + MOTOR Overload ALARM If b003 =2.4Amps and P033=1.4 Amp, the motor stops <1min + MOTOR Overload ALARM if b003=2.4Amps and P033= 1.8 Amps the motor stops after >1min + MOTOR Overload ALARM We received a tip that with parameter A495 (AF=3) set to 1of 2, we could get a reduction in RPM. But we neither see a reduction RPM (b005) nor a reduction in load (b003), To me this indicates that p033 has no direct infuence on A495 ór that A495 is not the correct parameter to reach for our goal E.g. when I delve in the the manual(s) I don't see P033 under related parameters at A495 and vice versa. As for parameter A495, what do: Reduce CLim and Reduce PWM mean and what do? PWM stands for Pulse-With Modulation and CLim for current limit? (Which current?) So, the next question is: If A495 in combination with P033 does not reduce the RPM/LOAD, which parameter does? A493 perhaps? ### Assistant: Hi van der Horst, This technote might help if you have not already found it: BF28311 Regards, RM \\n

### Human: POWERFLEX 525 DRIVE STARTING ISSUE Hi, I'm using powerflex 525, I'm giving speed command drive and it is reflecting in drive Hz, but if I give start command it's still in ideal, Before it was running perfectly ### Assistant: Hello Suresh, There are three start sources P046, P048, P050 (start source 1, 2, 3) There are also there speed references P047, P049, P051 (Speed ref 1, 2, 3) If using ethernet IP (for example) as start source and speed reference the use P046 and P047 change these parameters to the correct value. It is important to make sure any of the other start source and speed ref cannot be set to the same value. Start source 3 and speed ref 3 are set to Ethernet IP by default and will need to be changed in this case. Hope this helps. \\n


### Human: Kinetix 5700 to 5500 migration Hi I have a requirement to migrate kinetix 5700 drives onto the 5500 platform, initially it looks pretty straight forward but the 5700 drives have a configurable input setup as an external enable, unfortunately this enable input is not available on the 5500 drives. Both models of drives are mounted as a block but 5700 drives are dual modules and 5500 are single am i missing anything regarding 5500 features? can i disable an individual drive from an electrical signal? is there an example where disabling using a configurable input would be advantageous or is it generally a legacy thing is it to make it easier to disable a single axis of a dual module? As i am using a MSO/MSF within the program i can still enable/disable the drive from the software so i still have control and the STO handles the safety side i would be interested to know the general opinion Thanks Andy ### Assistant: EDIT: modified text better highlighted to avoid confusion -FL Hello Fentiman Moving from K5700 to K5500 is not a very common move :) there is some important differences . K5700 needs a Power supply , where K5500 do not , it's more a stand alone drive with some DC bus sharing capability. And K5500 is a single axes drive. Kinetix 5500 Servo Drives User Manual (rockwellautomation.com) K5500 do not support (for the most important topic): MP Motors , only VP motors are supported EDIT: MP are supported with a converter Kit No advanced safety feature , Only wired STO or Networked depending of the Version. Do not support the same advanced tuning features K5500 do not have an auxiliary encoder input Support 2 digital inputs (4 for the K5700) Regarding your question : can i disable an individual drive from an electrical signal? you can Enable or Disable the drive with the instruction MSO or MSF . as you said the STO can be also used. Why do you need a hard wire Enable ? If you need MP motor control , look also at the K5300 drive regards \\n

### Human: Powerflex 525 - Ethernet IP - Third Party PLC Hello All, I'm new to this forum, and have searched for documentation regarding the Powerflex 525 and the addressed / registers of the EDS File. I have used the 0001009600090500.eds file, downloadaded from the rockwell site. I use the embedded ethernet port and use the drive in single drive mode. I also see a different eds file folder EDS_PF525_V6 which also contains PF525 single drive mode, embedded ethernet port eds files? WHat is the different. If you add a drive in RSLogix you can see all bits named correctly (Speed reference, start, stop, at speed, etc) This is not the case when I import the EDS file. And cannot find this in the documentation, where can I find this? I use a Unilogic PLC. I want to have at least the following data: CMD Start CMD Stop (or not start) CMD Reset STS At Speed STS Running STS Faulted STS Actual SPeed STS Error code ### Assistant: Hi de Vries, The Add-On Profile (AOP) is what organizes the PF525 data into user-friendly tags, not the EDS. (Unless I am way off-base?) Here is a technote on using the PF525 as a generic device that tells you which bytes correspond to each of the registers you mentioned (e.g. CMD Start, Speed Reference, etc.): QA54660 Also see appendix D of the user manual: https://literature.rockwellautomation.com/idc/groups/literature/documents/um/520com-um001_-en-e.pdf Regards, RM \\n


### Human: PowerFlex 700S speed control I have a PowerFlex 700S firmware ver 4.002 Series:A and need to control motor speed using a 4-20mA analog input. I have successfully configured and run the drive using Par 14 - Preset Speed 1, encoder feedback, digital inputs 1 & 2 as Enable & Run, but I can't get the analog input to set the speed setpoint. I can see the analog input and a value in Par - 800 Anlg In1 Data, but the speed reference is not being written to Par - 40 Selected Spd Ref when I set Par 27 - Speed Ref A Sel to Spd Ref 1 and Par 28 - Speed Ref B Sel to Spd Ref 1. Can someone please explain what I need to configure to get analog input 1 as the speed reference? Can I use a 4-20mA signal with this drive, or does it require a 0-20mA signal? ### Assistant: EDIT: linkified for convenience -FL I think one thing missing here is to link the value of Analog Input 1 (parameter 800) to parameter 10 [Speed Ref 1]. This action is confirmed on Technical note https://rockwellautomation.custhelp.com/app/answers/answer_view/a_id/441489 On this specific drive, parameters can be linked easily via the HIM/display. There is a short example of how to link parameters available from page 157 of the October 2022 edition of the PowerFlex 700S High Performance AC Drive-Phase II Control Programmin manual. Please see link below: https://literature.rockwellautomation.com/idc/groups/literature/documents/pm/20d-pm001_-en-p.pdf There is also a more detailed configuration example of the Analog Input 1 available from page 15 of the 2011 edition of the PowerFlex 700S AC Drives Phase II Control Reference Manual. https://literature.rockwellautomation.com/idc/groups/literature/documents/rm/pflex-rm003_-en-e.pdf There might be required further fine adjustment of the scaling or offset, but I think after linking parameter 800 to parameter 10, the PF700S drive should start generating PWM waveform following the analogue input values. \\n


### Human: using a single servo for multiple functions I have a servo that operates a module on a machine and this module is not always used on all products. if the module (but not the servo) was removed when not in use and potentially an alternate module fitted, would it be possible to have 2 sets of parameters for the same servo? Could i load a different set depending on the product that has been selected to run enabling me to use the same servo/drive (assuming it was the correct size)? Would it be possible use two axis tags (one for each module) that would write into the selected axis tag structure upon product selection? Or would I need to make the 2 modules virtual axis that would gear to the physical axis depending upon product selection? It would be good to know any thoughts on this topic Thanks Andy ### Assistant: Hello Andy, So if I understand you would like to change the Axis parameters of your servo , to adapt to a different mechanical set that change depending of the production batch that you are doing... correct? If it's what you would like to do, yes it is possible , you have different options by using GSV/SSV instructions and in some cases MSG for the different parameters that you need to change , like Scaling, Tuning, inertia...etc You must do it axis disable. There is other solutions but they are mostly based on the same principal. You could also Inhibit and Un-inhibit axes... I guess you could find some info on RAKB Using the 2 virtual axis that you gear alternatively to the physical , can be a solution, if the mechanism have the same specificity , so you will not have to retune your axis (unless you have Load observer and Tracking notch to compensate if you are still in the BW of those features).

### Human: PF525 driving a flywheel We have several flywheel-driven machines. About a year ago, we installed a 15HP Powerflex 525 drive in simple V/Hz mode with DB resistors on one of the machines. It's been running great for that whole time. We have it set up so the STOP input (terminal 1) is wired through the DB resistor thermostats, input 2 is Run FWD ,and input 3 is Run REV. Since it's replacing an across-the-line reversing starter that's in the midst of a bunch of hard-wired relay logic, Relay 1 is Ready/fault and will cause the relays that control inputs 2 and 3 to drop if the drive faults. This arrangement has been running fine on machine ### Assistant: Joe E. Try swapping the motors. If the second motor is low inertia (compared to the first motor), it might be more difficult for the VFD to regulate the motor speed. \\n


### Human: PF525 utilizing a Line Reactor I'm curious if it's possible (and safe) to group multiple PF525 drives on a single line reactor. I am designing a panel that contains fourteen (14) 10hp drives and ideally, I don't want to have a line reactor for each individual drive. Can I group 2-3 drives per line reactor, and if so, how do I go about sizing the correct line reactor?

### Human: PowerFlex 700S Migration Dear good afternoon, I wanted to know what is the exact replacement for my PowerFlex 700S drives, since on the Rockwell page only power flex 755TS appears generically, please your support to be able to make the correct replacement. 20DC037A0EYNANANE 20DC022A0EYNANANE 20DC5P0A0EYNANANE I must highlight that I have my drives in an ethernet network with my 1756-L61 V16 processor, 1 1756-ENBT module and Point IO 1734-AENT. In addition, each drive controls 1 motor with an incremental encoder with the following characteristics: Thank you very much for your help. ### Assistant: Hello, please note that the local Rockwell distributor or commercial channel should be the first point of contact to discuss the exact replacement of a PowerFlex 700S phase II drive with a more modern drive. Please also note that the parameter set, terminal connections, physical dimensions and other features may not be the same between the currently obsolete 700S phase II drive and the newer PowerFlex drive chosen, which means that additional engineering design time and considerations should be taken into account, as the migration will not be a like for like drive replacement. PowerFlex 700S Drive Frames 1…6 to PowerFlex 755TS Drive Frames 1…6 is a very comprehensive guide that can help to specify more precisely the exact replacement. In particular, there are some tables in chapter 1 that correlate the power ratings of the drives, adding dimensions. That could be a good starting point for the selection of the right 755TS drive to source. Regards, \\n


### Human: Kinetix 5500 Servo Driver H015 FLT S25…PRECHARGE FAILURE Hi, I had two kinetix 5500 servo driver H015 will show FLT S25…PRECHARGE FAILURE error on the drive whenever it being power up with DC 24V & single phase AC 240V simultaneously. I read across the user manual for the power up sequence. It required to provide DC 24V first then wait until it turn to PRECHARGE state only provide the single phase AC 240V. I follow with this method and the error didn't not show & motor show RUNNING state. But I feel quite weird for the machine & driver that need to turn on DC & AC voltage at different time. Anyone meet this issue & any solutions I can deal with this condition so that my panel able to power on the DC & AC at the same time & the servo driver able to run? ### Assistant: Hello, the power up sequence of the Kinetix 5500 servo drive, as mentioned early on this thread, is clearly documented on Publication Kinetix 5500 Servo Drives User Manual. By design specifications, the Kinetix 5500 servo drive needs to be powered up following that order. After applying the 24V DC control power, the LCD display begins the startup sequence, which includes a self test that requires a few seconds, before the axis state can reach the PRECHARGE state. Is that time when three phase AC power should be applied. If the AC voltage and DC voltage are applied at the same time, the shunt resistor circuitry may not enable at the right time, which could generate these type of nuisance faults. More information about this via this technical note Kinetix 5500 No display or lights, not powering up . \\n

### Human: powerflex variable frequency drive 753 EDIT: moved to Drives and Motion community -FL Hi, I was using a powerflex 753 cat no -20F11 N D 022 JA0NNNNN and recently it burned . On investigation I found out that this frequency drive is designed for 480 v 60 hz input whereas power input provided was 400 v 50 hz . Has it burned due to wrong input as I later found out that for 400 v 50 hz cat no should be -20F11 N C 022 JA0NNNNN. Please clarify. ### Assistant: Hello Mohan, The VSD has the capability of swapping between 400V and 480V using parameter 305. Parameter 305 is set to either 400V or 480V depending on the Catalog number of the VSD. This lead me to believe that the voltage range of the VSD is capable of 400V or 480V. This is explained in QA46486 and QA16097 I would suggest send the VSD to the repair shop, they will provide a detailed repair report indicating what components failed. Hope this helps. \\n


### Human: How to do parameter changes in Armorstart St 284GS like Powerflex. I am new to Armorstart ST 284GS drives. I cound not find any software to configure the parameter for this drive. How to change the parameter? Any software avaialble? in Studio 5000 V33 , Armostart AOP 1.0068 using . there is no parameter option avaiable. ### Assistant: Hi PMKG, ArmorStart ST 284GS AOP is available from Studio 5000 V24 to last. The configuration pages of Chapter 6 should be shown in the project. If not, the AOP is corrupted. Chapter 6 starting page 88: ArmorStart ST Motor Controller with Integrated Safety - User Manual, publication 280ES-UM002. The configuration is slightly different that a PowerFlex, but all parameters can set. \\n


### Human: ArmorStart 284GS Internal communication error I Connected to 24V Powersupply. 480V is not Supplied to the Drive. I can see in Rslinx but its not communicating with PLC. Web page also not opening. Is it really 480V required for communication? Note : it is Factory delivered drive. ### Assistant: Yep, this is my biggest complaint with the ArmorStarts, is they seem to require 480VAC to actually do anything, including set the IP address. -RM \\n


### Human: PowerFlex 4M & PowerFlex523 4-20mA Input Hi Guys, I have 4 drives on the site: VSD 1, 3, 4 - PowerFlex4M VSD 2 - PowerFlex523 I'm having some issues with reading analog input (4-20mA) from my PowerFlex 4M 2.2kW drives. These analog signals comes from PLC analog output and I have confirmed with multimeter on the PLC output points that they are giving out correct mA. For eg: At 16mA, VSD 1,3,4 - Parameter d021 is reading around 80%, instead of 75%. t213 - 0, t214 - 100 VSD2 - Parameter d361 is reading around 75% as it should. Since all PowerFlex 4M are doing the same behaviour, I might be missing out on some settings? Any advice would be appreciated. Thank You. Reference: 22F-UM001D-EN-E PowerFlex 4M Adjustable Frequency AC Drive FRN 1.xx - 2.xx User Manual (rockwellautomation.com) 520-UM001I-EN-E PowerFlex 520-Series Adjustable Frequency AC Drive User Manual (rexel-cdn.com) ### Assistant: Hello Maung, It seems the scaling is slightly off. I think in the 4M the scaling is based off the min and max frequency parameters P104 and P105 if I am not mistaken. These parameters may need some slight adjustments to align your VSD speed control with the PF525. Hope this helps. \\n


### Human: Kinetix 5700 axis and finding an object I have an application I'll be receiving where we will be using a Kinetix 5700 drive system to control stack crowders for a blank destacking application. My issue is we don't have good control over the stack location. I was wondering if there was a way for the Kinetix drive to find the stack location and perform its location based off its learned location. I'm envisioning that when the stack is loaded, the crowders would advance with low torque toward the stack. When the drive senses a jump in current, it would record the location and base its crowding operation off that location. I'm not a drives person, but is this something that may be possible? ### Assistant: Hello Scott What you try to do should be possible, this will require some code in your Logix controller, and can be challenging . You also could use the VTS to do this (virtual Torque Sensor) There is also a very common way to locate the position of an item that is unknown, it's the registration sensor. You can connect to the drive an accurate sensor that will detect the presence of the item, and take a picture (registration) of the actual position of your axis. since you know the relative position of your sensor (HW location) and the position of your axis when the item trigger the sensor you know now the position of your item relative to the actual axis location. So you can control move your axis to an accurate position relative to your item. this require some code in Logix aswell. If you are not familiar with Logix and Motion control , I strongly recommend you to get in contact with your local Rockwell Automation representative and request some onsite technical assistance, you will same time and money regards \\n


### Human: Kinetix 5500 FLT M02 Motor Data Range 17 I have a Kinetix 5500 servo drive with a fault Init FLT M02 Motor Data Range 17. I can't find anything that tells me what that fault is. ### Assistant: Hello Carbo There is a mismatch between the encoder and the motor data file Is it a new installation ? if it's the case check the encoder wiring (data Chanel or DSL) if not inverted. you can found detailed descriptions about the M02 fault in our knowledge base QA39044 or QA32377 Regards \\n


### Human: Kinetix 5300 Fault - PWM Frequency Reduced Hello, When I trigger the MSO block of the Kinetix 5300 drive, I get the 'Physical Axis Fault - PWM Frequency Reduced' error after a short while, even if I do nothing. I couldn't find anything about this problem and its solution in the docs. Does anyone have information? ### Assistant: Hello Gamze, This is a very strange fault indeed, because you can't adjust the PWM, so it must be a protection . It seem that the system foldback due to an overtemperature... but never seen this before Some questions for you : Is it a new Drive ? Check the drive temperature (you can check the Drive Temp on the drive Web page.) did there is any load attached on the motor ? if yes disconnect the motor from the load. and test again Run an Hookup test load disconnected and them an autotuning Make also sure that you have the latest FW on the drive. What is the drive and Motor ref ? Regards \\n


### Human: Kinetix 5500 Home and registration input Hi i have a Kinetix 5500 drive where i require 2 registration sensors and a home switch. with the Kinetix 5500 drive you have 2 inputs available and these inputs can be selected as the functions DI1 - Home & Registration 1 DI2 - Registration 2 When using the Home & registration input is it plausible to use 2 sensors for 1 input or is there a better way by using another input for the 3rd sensor on remote IO or the main PLC rack ive tried searching the RKB but cant find anything Thanks Andy ### Assistant: Hello @ndy. I never tested 2 different senors on the 1st input of the K5500. Look in the manual 2198-UM001M to see if the internal digital input circuitry is compatible with the sensors that you would like to use (Page62). To avoid damage on the output of the 2nd sensor if the 1st one is active , you can use diodes. But I never test it. The other options are the following, use a PLC digital input to generate the Home input. but in this case you have to create you're own Homing cycle. Or use a time stamped input to create a Soft registration input (more complex to implement), the 2nd option is not as good as a real registration for very dynamic application. regards \\n


### Human: PF755 Increment /Decrement Speed using 0-10V Hi , Is it possible to increment the PF755 speed in fixed amount using a 0-10V or -10V to 10V i.e if the drive receives 10V it will increment the speed by 2Hz and if it receives -10V the speed will decrement by 2Hz . I know it is possible using DI assignment but PF755 has only one input and that input is assigned to Run and dont have a seprate I/O card . Also since it is standalone VFD control over ethernet is not possible . We have a spring return Selector Switch which if turned in one Direction speed should increment by 2Hz and if it turned to another it should decrease by 2Hz. Can i connect a analog input to the drive through this such that drive receives +/-10V and accordingly increment/decrement speed by 2Hz ### Assistant: Hello, as pointed out on your initial post, the implementation of that application requirement would be possible configuring the MOP (Motor Operated Potentiometer) feature of the PowerFlex 755 with the help of 2 digital inputs. In the scenario presented, it looks like there are not spare inputs available to be used, so the straight forward implementation of the MOP feature will not be possible. To my knowledge, based on the MOP block diagram below, there is no indication that the switching of a +/- 10V analogue input will be triggering the 2Hz increase or decrease sought after on this application. More information on the MOP feature is available via chapter 6 of PowerFlex 750-Series AC Drives, Reference Manual Another possibility could be exploring if some sort of drive embedded DeviceLogix code could be implemented to mimic the MOP functionality of the MOP block diagram above. As any code creation task, this could be a time consuming exercise that may pose a challenge on its own, due to the real possibility of non being able to manipulate or access certain signals/registers on the drive via DeviceLogix. \\n

### Human: Electronic synchronization - Kinetix 5300 drive system Hi.. I am very new to this forum and to Kinetix drive system. I have following architecture in my project. Both PLCs are from allen bradley and they communicate over ethernet: From the PLC Machine 2, I get real time position data over allen bradley ethernet. From the position data, I need to move the MPL Servo motor connected to PLC-M1 so that, MPL servo motor runs in sync with the motor connected to PLC-Machine2. Which block needs to be used in this case from motion instructions manual? I tried MDAC block but it does not work. Is there any example available on forum or in studio5000 sample programs which illustrates similar analogy? Have a nice day..!! Thanks, Gaurav ### Assistant: Hello Kulkarni, and welcome to Engage. Your are using the Integrated Motion Logix with CIP motion axis , synchronisation can only be effective between AXIS . so we need to know what is the  real time position data  that you received from Machine 2 , in machine 1 , is a simple consumed REAL Tag or an consumed AXIS tag ? if it's just a real tag you can sync an axis on this data , you need an axis tag that is produced from Machine 2 and consumed on machine 1 . This is the only way to get an accurate synchronisation. What type of synchronisation do you need , velocity only or exact position as well ? usually for full position synchronisation we use the MAPC position came profile with a 1:1 ratio came profile. On the web you will found many video that show how to use a MAPC , use also the User manual (that you have) and the RAKB knowledge base. Sharing axis and generating came profile for servo axis are not that obvious and requires logix Motion and general motion control knowledge. this is why i strongly suggest you to get in contact with your local Rockwell Automation representative and request assistance. regards \\n


### Human: Powerflex 755 Electricity Shutdown Parameter Problem Hello Everyone, I have a strange problem on Powerflex 755. We use 15kW 30 A drive and do incremental position control. When we download parameters to the drive, the motor works fine but after we cut off the power and start the drive, the motor vibrates and runs loudly. After we upload backup file again and the motor starts fine again and after we cut off the power and start the drive, the motor vibrates and runs loudly again. There is a loop. Same thing for 20-HIM-A6. We can't see any parameter after cut off power. When we upload backup file again we can see parameters. How can we fix this problem? Can you help me? ### Assistant: Hello Emre, Do you have a Logix PLC communicating to this VFD via Ethernet? If so, do you have Automatic Device Configuration (ADC) enabled? I ask because if you are connected via Ethernet to a Logix processor and have ADC enabled, the PLC memory card is storing a copy of the VFD programming. So any VFD programming changes that you do AT THE DRIVE with the HIM module must then be uploaded into the PLC program. If not, then whenever control power is cycled to the VFD, the ADC system will see that the programming in the VFD is different from that in its memory and restore the programming from its memory back into the VFD, wiping out any changes you may have made locally using the HIM. \\n


### Human: how to transfer servo axis data from one plc to another plc in studio 5000 im have a servo in one machine connected to a AB PLC. and i want to make that servo as master servo and synchronize the two other servos which are present in another machine with different AB PLC as slave WRT to the master servo from first machine. so how i can transfer the axis data from one PLC to ano ther PLC as i want to use MAG instruction to build electronic gearing. ### Assistant: Hello Inkar, In your case you have 2 options. Option 1: in the Master machine you can produce this axis over ethernet IP (supported starting Logix v32). them you can creat a virtual axis in the remote machine (slave) that consume the data from the Axis produced in the master machine. Then depending of your need you can Gear, Cam any of the remote machine to the Virtual slave that is sync to your master axis on the master machine. If your application is bellow V32, you will have to use a CIP sync AOI (much more complex), at this stage please engage a Rockwell Automation support. Option 2: Buy a CIP motion encoder , and install it on the Master Machine, this encoder will be connected on the Network and processor of the remote (slave)Machine. This encoder will be seen as a real CIP Motion axis in the remote Machine, you can them use this axis as a master for the other axis on this remote machine. Them you just have to creat a PCAM , MAG..etc between this encoder and the axis that you need to synchronise on this slave machine. The Option 2 is the easiest, but require some investment. But do not require modification of the code of the master machine. The Option 1 is the most complex to implement, even more if you have a Logix version bellow V32 and you don't want to upgrade to V32... without support I will not recommend this one Regards \\n

### Human: Powerflex525 comm flt action parameter Hello, I want to ask when i have comm flt action parameter set on stop and communication loss would occur , Will it generate fault on drive ( i used getting when it was set on fault) ? And if i set this parameter in reverse on fault will drive only generate fault ? Im using external ethernet card . With fault setting it generated fault 73 eth comm loss . In plc is logic programmed that will stop drive immidiately if it recieves fault from drive . Thanks for answers ### Assistant: Hi Fitz, I think pages 34 and 35 of the Ethernet Adapter manual will probably answer your question: By default, if the drive is configured to receive commands over ethernet (Start signal, speed reference, etc.) then on comm loss the drive will fault and stop.

### Human: Motion Control Bit Evaluation When Using Motion Instructions in Structured Text I am using some motion instructions in structured text and trying to get a good handle on when the .ER and .DN bits get set and how they need to be processed differently than in ladder. Does anyone have a good reference or any sample code (good code) from rockwell (or others) on how we should correctly look at the motion control bit status when used in structured text? (the structured text programming guide is a bit vague and lacks examples related to motion instructions) For example, the code below the intent is to: 1. check to see if registration needs to be disarmed 2. disarm registration 3. check for error 4. continue on... ***************** if (Ax_Infd1XfrBelt.RegEvent2ArmedStatus OR Ax_Infd1XfrBelt.RegEvent2Status) Then MDR(Ax_Infd1XfrBelt,MI_I1TBReg2MDR[0],2); if (MI_I1TBReg2MDR[0].ER) then EM_Infeed.I1TB.ShtTrack.Val_MtnInstrErr:=MI_I1TBReg2MDR[0].ERR; EM_Infeed.I1TB.ShtTrack.Val_MtnInstrExErr:=MI_I1TBReg2MDR[0].EXERR; end_if; end_if; ************* But questions come up... like 1. When does .ER bit get set? Before leaving line with MDR so it can be checked write after? or some other time later? 2. When does .DN bit get set? In ladder it says it may take a few scans... is it the same in structured text? Does that mean I need to set motion instruction and then go wait for either .DN or .ER before continuing? Is there any cases where neither get set in a reasonable time... If anyone has done a lot of motion instructions in Structured text and has a guide or best practices, I would appreciate some feedback Thanks ### Assistant: Hello Eric Bryant, 1st you should find details for each motion instructions in this manual. Those tags are part of the motion control tag that is associated with each Motion instruction. it's a status of the instruction. they are not mandatory to use, but they can help a lot in your application. The .ER is for the instruction Error status tag, and comes with the extended error code .ERR. So if you have a fault on your instruction (.ER) it means that your instruction have not been executed correctly (state, configuration...etc), that does not mean that you axis is in fault. so Monitor this tag to make sure that all works perfectly in your code. Them if .ER occurs monitor .ERR , the tag value is a code for fault description (all details in the like that I provided)... but once again this is not required, but can be very handy for maintenance. Regarding the .DN it tells you that the instruction have been executed , does not mean that your action is finish, this is why you also have the .IP or .PC... The .DN can be used like an interlock, you can also reset it when needed , this way you can easily manage the start of the your motion instruction, if you interlock it with a .DN. again all details in the link that i have provided. So what ever the type of language you use, the usage of those tag is the same. if you understand the meaning of those tag and how the behave , you can decide to use them in your code to achieve your goal. but there no general rules about those tags. Let me know if you need more detail Maybe someone will add some additional details regards Vincent \\n

### Human: PF755 with UFB feedback card connected to full digital SSI IFM encoder model RM8001. Bad velocity feedback. PF755 20G11NC060JA0NNN, firmware 16.002 20-750-UFB-1, firmware 1.015 I'm testing a lifting application. In this application is very importat to know the position of the load. In order to know load position, we read feedback position of motor encoder. If we use a simple incremental encoder, every drive disconnection implies to readjust home position. To avoid this, we choose an absolute encoder. To reduce the number of wires from the encoder to the drive, we choose an absolute full digital SSI encoder (IFM model RM8001). In the drive we have a 20-750-UFB-1 feedback card. This card is able to read SSI devices. We connecte SSI encoder according to Document ID BF14673. But parameter 6 equal to 9 (SSI FD ChX) We programmed UFB card according to Document ID QA28660 Parameter equal to 9 (SSI FD ChX) Parameter 8 equal to 0 Parameter 20 equall to 4 (Gray code) Parameter 21 equal to 12 (4096-12 bits per revolution) Parameter 22 equal to 13 (8192-13 bit number of revolutions) Now, UFB car shows the position from encoder with no errors. If i move drive the count changes increasing or decreasing depending movement up or down. The next step, i configure drive. I follow Document ID QA15265. In this document, after basic motor data programing. Is necessary to program feedback data. But prior to this we must check feedbak. So we write in parameter 132 a 40005 (Port4: Feedback 0) then, i move in VHz the drive monitoring paramenter 134. PROBLEM Te speed i see in parameter 134 is bad. Not stable, like ramdom. Numbers i'm not able to understand. For example, i move drive at +10Hz. In parameter 134 appear number between 0 and 1500 more or less. The accuracy is better if i write in paramenter 133 a 7 (3R/S noise) then in 134 i read from 0 to 16. In parameter 26 of UFB card i tested all possible values to sampling time, but results are simmilar. Where do you think is my problem? Thanks ### Assistant: Have you tuned the drive or the speed loop yet? Based on your pretty detailed post (thank you, btw) you really only got to the point where you are doing a direction check. and have not actually tuned the drive or the speed loop in QA15265. Based on your post, this is where you stopped: Which is only to check the direction of the encoder, not a final speed feedback check. If I misread your post, I apologize. Regards, RM \\n

### Human: Kinetix 5100, disconnect encoder without fault Hello, I would like to know if it is possible, by ethernet ip, to disable the kinetix 5100 drive, it is to be able to disconnect the encoder (through an ATI tool changer), so that, while it is energized, to be able to make the change, and it does not cause an non-recoverable fault, since the way I know to reset the non-recoverable fault is to power cycle or reset the module, and it takes a long time. Another question, if the tool changer is used constantly, while the drive is energized, can it cause damage? Thanks a lot. ### Assistant: Alejandro I cannot find any documentation to suggest the encoder is RIUP (Removeable or Insertion while Under Power). This can be interpreted as the encoder connection was not designed/tested nor supported for RIUP. If the Kinetix is power but the CIP axis is disabled (open loop), I believe it is still reading the encoder position and it would register an encoder fault. https://rockwellautomation.custhelp.com/app/answers/answer_view/a_id/1090640 data-linkindex=0>Kinetix 5100 Servo Drive E011 Encoder Error Troubleshooting \\n

If yes will setting be saved in drive if power loss would occured ? or it should be done offline? parmeter c121 comm write mode is set as default - Save on this setting parameter change should be written to eeprom right?, i have read also attention that repeated write of parameters can damage eeprom ,but if it is changed once it should be ok right? ### Assistant: Fitz The AOP is software that is installed on your PC... The AOP communicates directly with the online drive and/or it can save data to the offline project (on your PC). Most the the parameters can be changed while online with the drive (assuming the drive is not running the motor). Some parameter cannot be modified while the motor is running. When C121 = 0, the parameters are saved, they are saved to EEPROM. \\n

### Human: Powerflex 525 - Phase loss Hello , I want to ask if this setting “A557 phase loss detection” is parameter that can be used to detect phase loss on 3 phase motor . And if “phase loss treshold” A576 is set good if default is 25% for induction motor . My power supply is 400Volt AC as for Europe , i was wondering if 25% phase loss treshold is good set for this kind of power supply , because american is 460 volt if iam correct. I just need it to do its job and detect the phase loss. I don't currently have a vfd to test it on, that's why I'm asking. Thanks for answers ### Assistant: Hello Fitz, This parameter is used to monitor the output phases only. If an output is removed, there is a motor wiring issue or the voltage falls below the threshold the drive will trip on F021 Output Ph Loss. 25% of 400 is 100Volts so you would need to lose 300Volts on a phase to trip. Hope this helps. Thanks \\n

Ideally, I am looking for: -Power on time (such as DC Bus charged, but servo not enabled) -Actual runtime (-Servo On/Enabled) I know I can just use the DC Bus and ServoActionStatus tags in Logix to monitor these conditions, but I am wondering if there is any dedicated runtime counters or clocks already built into the Kinetix/CIP tag structure that is already collecting this data. ### Assistant: Hi Sean You can use MSG instruction to access some of those Diagnostic attributes, you can also access them via the drive webpage this is the attribute list: in this document the attributes ID are in decimal and in the MSG they must be converted to Hex Go to the Rockwell Automation Knowledge base article QA63499. to find how to use MSG for this application. If you use dual axis drive, the axis 1 will have Instance 1 and axis 2 will have instance 3 . Be careful in the doc document in the article, there is a little error : they have inverted attribute and instance in ligne d and e. EDIT: now corrected, thanks! Regards \\n


### Human: Kinetix 5500 stuck at precharge when servo motor is connected. I have kinetix 5500 with VPL-B1153F-P motor. When I disconnect the servo motor cable and give 24VDC and 480VAC drive stars up and DC bus voltages rises to 700V. Now when I connect the motor cable to the drive and give 24VDC and then 480VAC, the drive gets stuck at precharging state and DC bus voltage stays at 0.2V. I can't understand why it is doing this and why connecting the motor will stop the DC bus from charging. I would appreciate if anyone can help me with this. Thanks ### Assistant: Hello Hem Shah Could you please give me the actual FW revision of this drive,please ? And also tell me if the installation was working or if it's a new installation in startup ? Check also this article on QA20119 on our Knowledge base. regards \\n


### Human: PowerFlex 525 7.001 Firmware Update Not Flashing I am trying to flash the firmware of a PowerFlex 525 from 5.001 to 7.001 without success. I am using ControlFlash 15.07 with Windows 11. I am able to see and pick the drive in ControlFlash, but it errors out at the end. The message I receive is ERROR: Update to target device failed. Press View Log for more detailed information. Has anyone else experienced this issue? ### Assistant: Harding Please open the log file as it will provide information about why the flash was not successful. If the firmware in the drive becomes corrupt, you might try flashing via USB. ID: QA25514 | Access Levels: TechConnect PowerFlex 525 Drive Fault F125 [Flash Update Req] \\n


### Human: PowerFlex 523 - static vs dynamic autotune IR Voltage Drop Hello, We have a few PowerFlex 523 drives, all setup in the same manner and connected to identical motors. Static autotune was done on all of them and as a result the parameter 496 (IR Voltage Drop) was automatically set by the drives to a value in the range 22-24 V, each drive having slightly different value. Then, dynamic autotune was run on two of these drives and the parameter 497 was automatically set on them as expected, but also these drives changed their parameter 496 to a completely different value - 40V. Is this normal for dynamic autotune to override parameter 496? The updated value was not just slightly different. Static autotune sets it to 23.8V, then dynamic autotune overrides it to 40V, the difference is about 16V. Is dynamic autotune able to sense the voltage drop better and hence updates this value or is this erroneous behavior? ### Assistant: Hi Nickolay, The Static Tune Par 70 =2 can be performed in SVC and FV modes (Par 35) no matter if motor has or not a feedback encoder. It usually gets a reasonable value for the most of applications. The Dynamic Tune Par 70 = 3 only returns valid results with FV with feedback, or SVC with uncoupled load. If your application doesn't have a feedback encoder, the best solution is the Static Tune. It is explained in page 61, speaking about the Par 70: PowerFlex 750-Series AC Drives - Programming Manual. Publication 750-PM001. Paragraph: Important: If using rotate tune for a Sensorless Vector (SV) mode, the motor should be uncoupled from the load or results may not be valid. With a Flux Vector (FV) mode, either a coupled or uncoupled load will produce valid results. \\n
