After the power loss of the grid, when the bus voltage drops to the instantaneous power loss
frequency-decreasing point, the VFD begins to decrease the running frequency according to the
decreasing velocity and make the motor in power generation again. The feedback power can maintain
the bus voltage to ensure the continuous running of the VFD until the recovery of power.

Note:
1. Adjusting the parameter properly can prevent the stop caused by the VFD protection during shifting the
grid.
