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.07.02.
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.
