running (cause by the stop command, fault or
power loss), run from the first stage after
restart.
1: Continue to run from the stop frequency;
stop during running (cause by stop command
and fault), the inverter will record the running
time automatically, enter into the stage after
restart and keep the remaining running at the
setting 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.
