This feature means that in an instant power failure or a sudden drop in voltage, the inverter by reducing the output speed,
back to reduce the load energy compensation inverter DC bus voltage to maintain the drive continues to run.
If P9-59 = 1, the instantaneous power failure or a sudden drop in voltage, the inverter deceleration, when the bus voltage is
restored, the drive accelerates to the set frequency normal operation. Analyzing the bus voltage returns to normal is based on
the normal bus voltage P9-61 and lasts longer than the set time
If P9-59 = 2, the instantaneous power failure or a sudden drop in voltage, the inverter will decelerate to a stop
