is performed before motor overload. The larger the value is, the less advanced the pending
will be.

during deceleration of the AC drive, the AC drive stops deceleration and keeps the present
running frequency. After the bus voltage declines, the AC drive continues to decelerate.

result will be poor and an overvoltage fault may occur.
If the overvoltage stall gain is set to 0, the overvoltage stall function is disabled. The
overvoltage stall protective voltage setting 100% corresponds to the base values in the

deceleration of the AC drive, the AC drive stops acceleration/deceleration and keeps the
present running frequency. After the output current declines, the AC drive continues to
accelerate/decelerate.
