Description:
These parameters configure the vector mode Ride-Through PI controller, which is responsible for keeping the DC
link voltage at the level set in P0322.

Normally the factory settings for P0325 and P0326 are adequate for the majority of the applications. Do not
change these parameters.

12.8 DC BRAKING [47]

NOTE!
DC break on the start and/or stop will not be active if P0202=4 (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.
