After the grid powers off, the bus voltage
drops to the frequency drop point at transient
power-off, the VFD begins to decrease the
running frequency based on P11.02, to make
the motor generate power again. The
returning power can maintain the bus
voltage to ensure a rated running of the VFD
until the VFD is powered on again.
