0: Decelerate to stop: after the stop command
becomes valid, the inverter decelerates to
reduce the output frequency during the set
time. When the frequency decreases to 0Hz,
the inverter stops.
1: Coast to stop: after the stop command
becomes valid, the inverter ceases the output
immediately. And the load coasts to stop at
the mechanical inertia.

Starting
frequency
of DC
braking
Starting frequency of DC braking: start the DC
braking when running frequency reaches
starting frequency determined by P1.09.
Waiting time before DC braking: Inverters
blocks the output before starting the DC
braking. After this waiting time, the DC
braking will be started so as to prevent
over-current fault caused by DC braking at
high speed.
DC braking current: the value of P01.11 is the
percentage of rated current of inverter. The
bigger the DC braking current is, the greater
the braking torque is.
