Over-current Stall Prevention during Operation
Default: 120
Settings Light load: 0–130% (100%: drive’s rated current)
Normal load: 0–160% (100%: drive’s rated current)
This parameter only works in VF and SVC control modes.
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.
