power loss
After the power loss of the grid, when the bus voltage drops to the instantaneous power loss
frequency-decreasing point, the inverter begins to decrease the running frequency according to the
decreasing velocity and make the motor in power generation again. The feedback power can maintain
the bus voltage to ensure the continuous running of the inverter until the recovery of power.
Note:
1. Adjusting the parameter properly can prevent the stop caused by the inverter protection during
shifting the grid.
2. The function can be enabled only by disabling input phase loss protection.
