Overload (oL)
The AC motor drive detects excessive drive output current.
Overload capacity:
1. Normal duty: Sustains for one minute when the drive outputs 120% of the drive’s rated output current. Sustains for threeseconds when the drive outputs 150% of the drive’s rated output current.
2. Heavy duty: Sustains for one minute when the drive outputs 150% of the drive’s rated output current. Sustains for three seconds when the drive outputs 200% of the drive’s rated output current.
The load is too large - Reduce the load.
Reduce the load during low-speed operation.
Increase the drive capacity.
Decrease the carrier frequency of Pr.00-17
