DC braking voltage:
The value of voltage which is injected to motor when executing DC braking function. The
value of voltage benchmark against the input rated current of inverter.
This function can output torque under zero speed. Generally, it uses to improve the stop accuracy and realize quick
stop, but it can’t be apply for normal deceleration. The inverter will stop output once DC braking has been
performed. If the DC raking current set to big, over current fault occurs easily during stop.
DC braking time when stop:
DC braking current lasting time when inverter stops, if the braking time is set to 0, it
means the DC braking function is disabled.
DC braking starting frequency when stop
It means when inverter decelerated to this frequency, the inverter
will stop output, and perform the DC braking function. If the output frequency less than DC braking starting
frequency when stop during running process, the inverter will stop output, start DC braking function when receiving
the stop command.
The inverter will start DC braking, and the output frequency jump to zero if the frequency given less than DC
braking staring frequency when stop during the deceleration process. The DC braking staring frequency when stop
should be set smaller when there are no strictly requirement for stop. When the DC braking staring frequency when

The Jump frequencies are frequency ranges at which the drive will not operate. The drive can be programmed with
three separate Jump frequencies to avoid operating at speeds that cause resonance in driven machinery. If the
frequency reference falls within a Jump frequency dead band, the drive will clamp the frequency reference just
below the dead band and only accelerate past it when the frequency reference rises above the upper end of the
dead band.
