Cause : Overspeed comes when the motor speed feedback exceeded the F1-08 setting. Overshoot is occurring, reduce the C5-01, Speed Control Proportional Gain 1, setting and increase the C5-02, Speed Control Integral Time 1, setting.

  • If using Closed Loop Vector mode, enable Feed Forward and perform Inertia Auto-Tuning.
