Over-current Stall Prevention during Operation
Default:
120/120/120/120
Settings 230V/460V series
Light load: 0–130% (100%: drive’s rated current)
Normal load: 0–160% (100%: drive’s rated current)
575V/690V series
Light load: 0–125% (100%: drive’s rated current)
Normal load: 0–150% (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.
