oL Over Load - The output current causes the motor drive to be overload. If the output current is 150% higher than the drive’s rated current, the motor drive can sustain the output for a maximum of 60 seconds.
1. Check if the motor is overloaded.
2. Increase the output capacity of the motor drive.
Check drive rectifier & IGBT using multimeter.
Check wiring.
Check drive hardware using multimeter.
