When a Stop command is given, the drive will enter the current set to b2-01 to the motor after
waiting the minimum baseblock time set to P2-01. DC Braking to Stop significantly shorter the
stopping time compared to Coast to Stop.

DC Braking time is determined by b2-03 (DC Braking Time at Stop) and the output frequency
when a Stop command was entered.
DC Braking time = (b2-03)×10×Output frequency / d1-02(Maximum output frequency)

Note: If an OCD (Overcurrent) fault occurs, increase the minimum baseblock time to P2-01.
