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.

The actual increasing ratio is less than the ratio
of output frequency because of the big load
