Cause : Motor speed has exceeded the over speed threshold comes when the motor is rotating at a speed higher than the specified limit.

  1. Increase the over speed trip threshold in Pr 3.08 (closed loop vector and servo modes only).
  2. Speed has exceeded 1.2 x Pr 1.06 or Pr 1.07 (open loop mode).
  3. Reduce the speed loop P gain (Pr 3.10) to reduce the speed overshoot (closed loop vector and servo modes only).
