frequency)
After the power loss of the grid, the bus
voltage drops to the sudden
frequency-decreasing point, the inverter begin
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. Prohibit the input phase loss protection to
enable this function.
