After the power loss of the grid, the bus voltage
drops to the sudden frequency-decreasing point,
the VFD begin to decrease the running
frequency at P11.02, to make the VFD generate
power again. The returning power can maintain
the bus voltage to ensure a rated running of the
VFD until the recovery of power.
