Cause : Overload protection for components inside the motor drive. Power components inside the motor drive reach the overload protection level.
1. Decrease the load of the motor drive.
2. Decrease the carrier frequency (Pr.00-17).
3. Improve the heat dissipation of the distribution box.
4. Increase the acceleration time.
5. Use a motor drive with larger capacity.
6. Decrease the current limit (Pr.06-03, Pr.06-04, Pr.06-12).
