Over-current during acceleration
1. Short-circuit at motor output: Check for
possible poor insulation at the output lines.
2. Torque boost too high: Decrease the torque
compensation setting in Pr.7-02
3. Acceleration Time too short: Increase the
Acceleration Time.
4. AC motor drive output power is too small:
Replace the AC motor drive with the next
higher power model.
