These two parameters respectively define the time proportions of the start segment and the end segment of
S-curve acceleration/deceleration. They must satisfy the requirement: P6-08 + P6-
09 ≤ 100.0%.
In Figure 6-11, t1 is the time defined in P6-08, within which the slope of the output frequency change
increases gradually. t2 is the time defined in P6-09, within which the slope of the output frequency change
gradually decreases to 0. Within the time between t1 and t2, the slope of the output frequency change remains
unchanged, that is, linear acceleration/deceleration.

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

P6-11 (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 P6-11.
P6-12 (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 overcurrent caused due to DC
braking at high speed.
P6-13 (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
