If the bus voltage drops to the sudden
frequency decreasing point due to the
power loss of the grid, the inverter begins
to decrease the running frequency
according to P11.02 to make the motor in
power generation state. The regenerative
power can maintain the bus voltage to
ensure normal running of the inverter
until the recovery of power.
