text: <s>[INST] When drive is told to decel it stops Summary: when we tell the drive to decel it coast to a stop.I have a power flex 753 drive on a 250hp motor. The machine has been in service for 10 years, but we had a drive go bad a few weeks ago. We installed the new drive loaded the original parameter's back in, and it went back into production. We have a problem now that when you tell the drive to decel it goes to stopped. This started yesterday in the middle of production. The drive has a 110v adapter card that we send an analog input to for a speed reference. The drive shows that it is still enabled, and it is still being told to run. I am also trending the command speed with drive observer, and it is not dropping out either. I even put latch bits in the PLC to make sure that the drive commands are not blinking. The other thing I noticed is that the last stop source, and the last start source bot say pwr removed. I have looked all over for more clarification on what this means, but cant seem to find any. We are going to change the adapter card this morning, and see if that makes a difference. I am also going to hook a process meter up to the drive, and send it an analog signal just to verify the wiring. I am able to start the drive and ramp it up I can start and 30hz and ramp it up incrementally no problem. The problem only occurs when trying to slow it down. I have a breaking resistor installed as well, but the dc buss doesn't even go up. If we want to start the drive back up, then we have to cut off the start signal and turn it back on again. There is no faults or warnings on the drive, and it still shows enabled. I have included a screen shots for reference as well. I guess my question is has anyone ever had a drive do this? I have looked in knowledge base, and forums but cant seem to find anything. [/INST] Can you upload the drive DNO file for us to look at? \\n </s>
