After the power loss of the grid, the bus
voltage drops
frequency-decreasing point, the VFD begins
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:
 Adjust the parameter properly to avoid the
stopping caused by VFD protection during
the switching of the grid.
 Prohibit the input phase protection to
