decreases to 0Hz, the VFD stops.
1: Coast to stop: after the stop command becomes valid,
the VFD ceases the output immediately. And the load
coasts to stop at the mechanical inertia.
P01.09
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: VFDs 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 VFD. The bigger the DC
braking current is, the greater the braking torque is.
DC braking time: the retention time of DC braking. If the
time is 0, the DC braking is invalid. The VFD will stop at
the set deceleration time.
