The start frequency of stop DC braking is also valid during the deceleration process
when switching between forward and reversal.
If there is no strict requirement for stop brake under operating conditions, the start
frequency of stop DC braking shall be set as small as possible.

Braking wait time at stop: During decelerating and stopping, the time interval from the
moment when the operation frequency reaches the start frequency (F2.09) of braking to
the moment when the DC braking amount is applied.
There is no output of the drive during the waiting period of stop braking. This time
setting can effectively prevent the current overshoot at the brake start moment for high
power motors.
The setting of stop DC braking current is a percentage relative to the rated current of
the drive. When the stop braking time is 0.0s, there is no DC braking process.
The maximum deceleration of stop DC braking is a multiple of the current deceleration.
When the maximum deceleration of stop DC braking is 5.0, it is equivalent to that the
deceleration will increase by 5 times when the frequency reaches the start frequency of DC
braking.
Note: The stop braking current (F2.11) is a percentage relative to the rated current of
the drive.

The acceleration/deceleration time 1 is defined in F1.11 and F1.12.
The acceleration/deceleration time 1, 2, 3 and 4 can be selected through the
multi-function terminal. (Refer to group F6 parameters)
