b1-08 (Initial frequency of stop DC braking)
During the process of decelerating to stop, the frequency inverter starts DC braking when the running frequency is
lower than the value set in b1-08.
b1-09 (Waiting time of stop DC braking)
When the running frequency decreases to the initial frequency of stop DC braking, the frequency inverter stops
output for a certain period and then starts DC braking. This prevents faults such as over current caused due to DC
braking at high speed.
b1-10 (Stop DC braking current)
This parameter specifies the output current at DC braking and is a percentage relative to the motor rated current. The
larger the value is, the stronger the DC braking effects, but the more heat the motor and frequency inverter emit.
b1-11 (Stop DC braking time)
This parameter specifies the holding time of DC braking. If it is set to 0, DC braking iscancelled. The stop DC
braking process is shown in the following figure.

b2-00
JOG running frequency
Default
2.00 Hz
Setting Range
0.00 Hz ~ maximum frequency
b2-01
JOG acceleration time
Default
Model dependent
Setting Range
0.0s~6500.0s
b2-02
JOG deceleration time
Default
Model dependent
Setting Range
0.0s~6500.0s
These parameters are used to define the set frequency and acceleration/deceleration time of the frequency inverter
when jogging. The startup mode is fixed as "Direct start" (b1-00 = 0) and the stop mode is fixed as "Decelerate to
stop" (b1-07 = 0) during jogging.
