If the bus voltage drops to the sudden frequency decreasing point due to the power loss of the grid, the VFD begins to
decrease the running frequency according to P11.02 to make the motor in power generation state. 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.
2. This function can be enabled only when the input phase protection function is disabled.
