Over load (oL)
The AC motor drive detects excessive drive output current. The overload capacity sustains for 1 minute when the drive outputs 120% of the drive’s rated output current.
When the load is higher than the protection level and exceeds allowable time, the oL protection activates.
The load is too large - Reduce the load.
Increase the setting value for Pr.01-12–01-19 (accel./decel time)
Reduce the load during low-speed operation.
Increase the drive capacity.
Decrease the carrier frequency of Pr.00-17.
Check the status of three-phase motor.
Check if the cable is broken or the screws are loose.
