DC-injection braking
Explanation of the automatic DC-injection braking function by means of two examples
Example 1
[5-3] Example 1: Signal characteristic for automatic DC-injection braking
Example 2
[5-4] Example 2: Signal characteristic for automatic DC-injection braking
 :
Speed setpoint
 :
Actual speed value of the motor
 :
Controller output current
 :
Pulse inhibit
 :
DC-injection braking is active
c :
The motor rotates with the selected
speed. The resulting current depends
on the load .
d :
The DC braking current set in C036
is
injected.
e :
