Dc Braking - Siemens SINAMICS S120 Function Manual

Parameterization of the example:
1. Set p1231 = 1.
2. Define DI 14 as input with p0728.14 = 0.
3. Connect the feedback signal of the external armature short-circuit contactor with terminal
4. Interconnect p1235 with r0723.14.
5. Define DO 15 as output with p0728.15 = 1.
6. Connect the control signal for the external armature short-circuit contactor with terminal
7. Interconnect p0745 with r1239.0.
8. Invert the output of p0745 with p0748.15 = 1.
The parameterization of external armature short-circuit braking has now been completed.

DC braking

Preconditions
● This function has been released for Motor Modules in the booksize, blocksize and
● An induction motor must be used.
With the function "DC braking", after a demagnetization time, a DC current is injected in the
stator windings of the induction motor. The DC current brakes the motor.
