6.2.26.3.1 DC braking: mode (Bit 0…2)
Currently, only one DC braking mode is implemented:
• Switching off the modulation for a preset time / reduction of the magnetic
flux
• Connecting a DC voltage vector for a parameterizable time
6.2.26.3.2 DC braking: start by digital input sel (Bit 3…5)
An activation condition is the start by digital input (Bit 3: start by digital input selec-
tion = "8: on“ or "16: on + speed level“)
An activation input must be selected in ds61 DC braking source:

With “start by digital input selection = 16: on + speed level“ the requested actual
speed level must additionally be set in ds62[7] braking speed level [%Nn].
6.2.26.3.3 DC braking: start in stopping state (Bit 6…8)
Start of the DC braking in state: “quickstop“, “fault reaction“, “shut down“, “disable
operation active”. During operation in the torque limit, the speed setpoint at the
ramp output can reach zero before the actual speed has fallen below ds62[7] brak-
ing speed level [%Nn].
To ensure that the DC braking is safely activated with the setting 128: on + speed
level, the waiting time before the modulation switch-off (pn45 fault reaction time)
must be configured accordingly.
