12.6 DC BRAKING
NOTE!
The DC Braking on the start and/or stop will not be active if P0202=5 (Vector with Encoder mode).
NOTE!
The DC Braking at start does not act when the Flying Start function is active (P0320=1 or 2).
The DC Braking consists in the application of direct current to the motor, allowing its fast stopping.
