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 VFD will record the running time automatically,
enter into the stage after restart and keep the
remaining running at the setting frequency.
0: Seconds; the running time of all steps is counted
by second
1: Minutes; the running time of all steps is counted
by minute

LED ones:
0: Input phase loss protection disable
1: Input phase loss protection enable
LED tens:
0: Output phase loss protection disable
1: Output phase loss protection enable

0: Enable
1: Disable
Setting range: 0.00 Hz/s–P00.03 (max. output
frequency)
After the power loss of the grid, the bus voltage
drops to the sudden frequency-decreasing point, the
VFD begin to decrease the running frequency at
P11.02, to make the VFD generate power again. The
returning power can maintain the bus voltage to
ensure a normal running of the VFD until the
recovery of power.
