Explanation of the automatic DC-injection braking function by means of two examples
[5-27] Example 1: Signal characteristic for automatic DC-injection braking of a drive without speed feedback
[5-28] Example 2: Signal characteristic for automatic DC-injection braking of a drive with speed feedback
 The motor rotates at a specified
speed. The current adjusts itself to
the load, see .
 The DC braking current set in
C00036 is injected.
 After the hold time ( C00106 ) has
expired, a pulse inhibit is set.

 The motor rotates at the selected
speed. The resulting current depends
on the load, see .
 The DC braking current set in
C00036 is injected.
 The actual speed value of the
motor follows the speed setpoint.
The resulting current depends on the
load.
