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.

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