Active Braking:
The motor actively provides a reverse torque
when decelerating, recovering some of the rotational energy.
Normal braking mainly relies on air resistance.
DO NOT use a direct-current power supply for testing to avoid
damage to the power supply when active braking function is
enabled.
* Refer to Active Protection Functions (p. 13) for details.
