Explanation of the automatic DC-injection braking function by means of two examples
[5-19] Example 1: Signal characteristic for automatic DC-injection braking of a drive without speed feedback
[5-20] Example 2: Signal characteristic for automatic DC-injection braking of a drive with speed feedback
c The motor rotates at a
specified speed. The current
adjusts itself to the load, see .
d The DC braking current set in
C00036
is injected.
e After the hold time (C00106)
has expired, a pulse inhibit is set.

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