Detailed instruction of parameters
Setting range: 0.00Hz/s~P00.03 (the Max. frequency)
After the power loss of the grid, the bus voltage drops
to the sudden frequency decreasing point, the
inverter begins to decrease the running frequency at
P11.02 to make the inverter generate power again.
The returning power can maintain the bus voltage to
ensure a rated running of the inverter until the
recovery of power.

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