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
, to make the VFD generate power
again. The returning power can maintain the bus
voltage to ensure a rated running of the VFD until
power recovery.

Note:
1. Adjust the parameter properly to avoid the
stopping caused by VFD protection during the
switching of the grid.
2. Disable input phase loss protection to enable
this function.
