Method
DC-injection braking can be carried out in two ways with different types of activation:

Manual DC-injection braking (DCB)

Automatic DC-injection braking (Auto-DCB)

5.10.5.1 Manual DC-injection braking (DCB)
DC-injection braking can be activated manually for the two technology applications
"Actuating drive speed" and "Switch-off positioning" by connecting the bSetDCBrake input
of the LA_NCtrl or LA_SwitchPos application block to a digital signal source (e.g. via the
digital signal source bCtrl1_B3 of the port block LP_CANIn1).
 For HIGH-active inputs, DC-injection braking is active as long as the signal is at HIGH
level.
 After the hold time (C00107) has expired, the controller sets the pulse inhibit (CINH).
5.10.5.2 Automatic DC-injection braking (Auto-DCB)
"Automatic DC-injection braking" (referred to in the following as "auto DCB") can be used
if there is a requirement that the drive be isolated from the supply at n

Note!
Deactivate automatic DC-injection braking when a holding brake is used!
