If the output current exceeds the setting specified in Pr.06-03 when the drive is operating, the
drive will decrease its output frequency by Pr.06-04 setting to prevent the motor stall. If the
output current is lower than the setting specified in Pr.06-03, the drive will accelerate (by
Pr.06-04) again to catch up with the set frequency command value.
