The AC drive detects excessive drive output current
1. Check whether the motor is overloaded.
2. Reduce torque compensation setting as
set in Pr.7-02.
3. Increase the AC drive’s output capacity.
4. Note: The AC drive can withstand up to 150%
of the rated current for a maximum of 60
seconds.
Check drive rectifier & IGBT using multimeter.
Check wiring.
Check drive hardware using multimeter.
