When the over-current stall prevention is activated, the acceleration time of the AC drive will be longer than the time set in Pr. 01-09.

This parameter selects the percentage of allowable over-current during operation before the stall prevention function is enabled.
If the output current exceeds the value specified in Pr.06-02 when the drive is operating at steady state speed, the drive will decrease its output frequency to prevent the drive from faulting with an OC. Once the current falls below the value specified in Pr.06-02, the drive will then accelerate to catch up with the command frequency.
