Refers to the moment when there is a power failure or the voltage drops suddenly, the inverter reduces the output
speed, so that the load feedback energy maintains the inverter DC bus voltage, so that the inverter continues to
run.
If 11-59=1, the inverter decelerates when there is an instantaneous power failure or a sudden drop in voltage, and
when the bus voltage returns to normal, the inverter normally accelerates to the set frequency. The basis for
judging the return of the bus voltage to normal is that the bus voltage is normal and the duration exceeds the set
time of 11-61.
If 11-59=2, during an instantaneous power failure or a sudden drop in voltage, the inverter decelerates until it
stops.
