(Pr. 57
Speed
You can restart the inverter without stopping the motor (with the motor coasting) when power is restored after
an instantaneous power failure.

REMARKS
When Pr. 162 = "1", the output speed before an instantaneous power failure is stored and output at the time of restart.
If the power of the inverter control circuit is lost, the output speed berore an instantaneous power failure cannot be
stored and the inverter will start at 0r/min.
