Selected / uint32Selects the source of the positive speed enable command.
1 = Positive speed enabled.
0 = Positive speed interpreted as zero speed reference.
In the figure below, 23.1 Speed ref ramp input is set to zero
after the positive speed enable signal has cleared.
Actions in different control modes:
Speed control: Speed reference is set to zero and the motor
ramps down along the currently active deceleration ramp.
The drive keeps modulating. The rush controller prevents
additional torque terms from running the motor in the
positive direction.
Torque control: The rush controller monitors the rotation
direction of the motor.
