(L2-03). When the minimum baseblock time has expired, the drive will inject the amount DC current set in parameter b2-02
into the motor windings to brake the motor. The stopping time in DC Injection Braking to Stop is significantly faster compared
to Coast to Stop.
Note: This function is not available in OLV/PM control mode (A1-02 = 5).
