Over-current Stall Prevention during Operation
Default:
Settings
Normal duty: 0–150% (100% corresponds to the
rated current of the drive)
120
Heavy duty: 0–200% (100 % corresponds to the rated
current of the drive)
180
This is a protection for the drive to decrease output frequency automatically when the motor
over-loads abruptly during constant motor operation.
If the output current exceeds the setting value for Pr.06-04 when the drive is operating, the drive
decreases output frequency (according to Pr.06-05) to prevent the motor from stalling. If the
output current is lower than the setting value for Pr.06-04, the drive accelerates (according to
Pr.06-05) again to the setting frequency.
