Detailed instruction of parameters
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.
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.
