0: Decelerate to stop
After the stop command is enabled, the AC drive decreases the output frequency according to the deceleration time and stops
when the frequency decreases to zero.
1: Coast to stop
After the stop command is enabled, the AC drive immediately stops the output. The motor will coast to stop based on the
mechanical inertia.

P1.11 (Initial frequency of stop DC braking)
During the process of decelerating to stop, the AC drive starts DC braking when the running frequency is lower than the value set
in P1.11.
P1.12 (Waiting time of stop DC braking)
When the running frequency decreases to the initial frequency of stop DC braking, the AC drive 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.
P1.13 (Stop DC braking current)
This parameter specifies the output current at DC braking and is a percentage relative to the base value.If the rated motor current
is less than or equal to 80% of the rated AC drive current, the base value is the rated motor current. If the rated motor current is
greater than 80% of the rated AC drive current, the base value is 80% of the rated AC drive current.
P1.14 (Stop DC braking time)
This parameter specifies the holding time of DC braking. If it is set to 0, DC braking is cancelled. The stop DC braking process is
shown in the following figure.
P1.11
Brake use ratio
Default
100%
Setting Range
0% ~100%
It is valid only for the AC drive with internal braking unit and used to adjust the duty ratio of the braking unit. The larger the value
of this parameter is, the better the braking result will be. However, too larger value causes great fluctuation of the AC drive bus
voltage during the braking process.
