Figure 8-65 Activating DC braking via a control command
Set p1231 = 4 and p1230 = control command.
The control command "DC braking activation" activates and deactivates the DC braking:
• 1 signal:
The converter de-energizes the motor for the motor de-excitation time p0347 in order to
demagnetize the motor.
The converter activates the DC braking.
• 0 signal: The drive switches back to normal operation.
