The function defines when instant outage or voltage suddenly drops, inverter compensating dc bus
voltage decrease by load feedback enery through decreasing output revolving speed, which maintaining
inverter running.
P9.59=1
：
When instant outage or voltage suddenly drops, inverter decelerates. Inverter normally
accelerates to the set running frequency until bus voltage came to normal. Bus voltage has restored to
normal is based on normal bus voltage duration time. If the time exceeds P9.61 set value , bus voltage is
normal.
P9.59=2
：
When instant outage or voltage suddenly drops, inverter decelerates to stop.
