Over-current Stall Prevention during operation

Settings

20~250%

Factory Setting: 150%

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.
