The braking time is defined with parameter DC braking time at stop. If high inertia
exists, it is recommended to use an external braking resistor for faster deceleration.
See Figure 5-14 .

DC Braking frequency at stop “Stop D-BrakeFr”
The output frequency at which the DC braking is applied when making ramping stop.

Scaling of DC-braking current “DC-currnt Sclng”
The DC braking current can be reduced with the free analog input signal between zero
current and the current set with parameter DC Braking Current.

DC Brake current in stop “DCBrakeCurlnStop”
Defines the current injected to the motor in stop state when the digital input signal
“DC Brake Command” is used to activate the DC brake when no run request is active.
When the DC brake is activated the drive will indicate being in Run state.
