Notes:

DC braking is injecting DC current to motor, to let it stop quickly, and keep the spindle of motor in
standstill until finished DC braking
 If there is pre-shoot or slewing during deceleration stopping or positive and negative dead zone, the value of
P1.11 can be decreased or increased appropriately.

DC braking frequency at stop is the frequency at which DC braking action begins when the inverter in
Dec-to-stop process. In the process of constant rate deceleration, if the output frequency is at or below the
"DC braking frequency at stop, the DC braking function will startup.
 The upper limit of the stopping DC braking current is 80% of the rated current of the inverter or the smaller
rated current of the motor.

When the stopping DC braking time is 0.0s, there is no DC braking process.
 Stopping DC brake time: It is DC braking current hold time. This time cannot be set too long, as this may
cause overheat of the inverter. If the DC braking time is equal to zero, then DC braking does not operate.
