After the users select the corresponding ACC/DEC time,
the combining 16 binary bit will change into decimal bit,
and then set the corresponding function codes.

PLC restart
mode
0: Restart from the first stage; stop during 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 VFD 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 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 rated running of the
VFD until the recovery of power.
