Cause : Tracking error comes when the difference between setpoint value and actual value exceeds the value in parameter 4-35 Tracking Error.

  1. Disable the function or select an alarm/warning in parameter 4-34 Tracking Error Function.
  2. Investigate the mechanics around the load and motor.
  3. Check feedback connections from motor encoder to drive.
  4. Select motor feedback function in parameter 4-30 Motor Feedback Loss Function.
  5. Adjust the tracking error band in parameter 4-35 Tracking Error and parameter 4-37 Tracking Error Ramping.
