Over-current Stall Prevention during operation

Settings
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.
