Figure 8-68 DC braking as a fault reaction
Set p2101[x] = 6 and p2100[x] to the corresponding fault code.
If you have de󹪝ned the DC braking as a reaction to a fault, then the following will occur:
1. The converter brakes the motor with OFF1.
2. The converter de-energizes the motor for the motor de-excitation time p0347 in order to
demagnetize the motor.
3. The converter activates the DC braking.
4. After "DC braking duration" p1233 expires, the converter de-energizes the motor.
