text: <s>[INST] kinetix 2000 changing (overtravel) pick n place position Summary: The horizontal axis on our automation is changing the set point the robot picks the part up at causing damage on part.How it works is the arm uses two axis horizontal and vertical the robot will pick up parts and place them in a tray. for example At start up the pick position set point would be set at 8.03 and while running the set point changes and it starts picking parts up at the position 8.53. that's .50 off from where it should be. when this change occurs the machine runs until we discover damaged parts. Any info on this matter would help. [/INST] Korben, the Kinetix 2000 gets all of its control commands from a Logix processor; it does nothing by itself. To help you, we're going to need a LOT more information. To start, you should share the ACD file from the logix processor so that people here can look at the logic. If you choose to share it with us, you'll need to identify which axis within the program is giving you problems. Is there ANY chance that something mechanical is slipping? You seem to be mixing terms in your problem statement. You talk about the set point position being 8.3, but the pickup position is 8.53. This last number - did you measure it yourself, or did the system HMI display the feedback position as 8.53, or did the position set point actually show as being changed to 8.53? The basic question to ask is: WHAT CHANGED? If the system was running well at some point in the past (yesterday, last week, whatever), but now behaves differently, WHAT CHANGED? Did a drive get replaced? Did a motor get replaced? Did the load the servo moves increase or decrease? If it used to work, and now does not, something changed. \\n </s>
