Over-current Stall Prevention during Operation

Settings
If the output current exceeds the setting specified in Pr.06-02 (the over-current stall
prevention current level during operation) 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.06-02, the drive will then accelerate to catch up with the
frequency specified.
