Over-current during acceleration
1. Check if the screws between the drive and motor are
loosen.
2. Check for possible poor insulation between the U-V-W
terminals to the motor.
3. Increase the Acceleration Time.
4. Decrease the torque compensation setting (Pr.07.02).
5. Replace the drive with a larger capacity model.
