During acceleration, the AC drive output current may increase abruptly and exceed the value
specified by Pr.06-03 due to rapid acceleration or excessive load on the motor. When this
function is enabled, the AC drive will stop accelerating and keep the output frequency constant
until the current drops below the maximum value.

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