After the movement function (MC_MOVERELATIVE) has been executed, some small reference remains, as a result of which the drive rotates slowly. Sometimes the drive starts to rotate as soon as MC_POWER is turned on. Link to video: [snip] The drive is controlled by Profinet. A TTL 1024 AB encoder (no zero mark) is connected to the inverter.

Try to move with drive control pannel, and compare values between TO and drive. Actual velocity and speed on drive side and position change depending on velocity. May be encoder configuration or referencevalues are wrong. Here is an example project: https://support.industry.siemens.com/cs/de/en/view/81666970

Then try to move with drive control panel. When this is OK use TO control panel and set precontrol to 100% and Kv = 10;

AutoGen_3618431 Regular Member Joined: 8/2/2019 Last visit: 1/12/2022 Posts: 12 Rating: (0)	Thank for your advice. It seems to work as it should. However, at Kv = 10, overshoot is observed. I started to decrease it and at Kv = 3 slow rotation started again :-( While stopped at Kv = 5. One more question. Is it possible to reset the encoder readings in p0482 with a command from the PLC (via Profinet)? Thanks again.
