SPEED CHANGING Bit
This read-only bit indicates if the motor is at a steady speed or if it is
accelerating or declerating.
1 = Motor is accelerating or decelerating.
0 = Motor is at a steady speed.
FORWARD MOTION Bit
This read-only bit indicates the direction of the motor. It also indicates if the
motor is stopped.
1 = Motor is rotating in the forward direction. If this bit is a logic 1 and the
actual frequency (location $0085 and $0086) is 0, the motor is
stopped.
0 = Motor is rotating in the reverse direction.
MOTOR ENERGIZED Bit
This read-only bit indicates PWM output activity
1 = All PWM outputs are active.
0 = The PWM outputs are inactive or the bottom PWM outputs are in the
pre-charge cycle.
RESISTIVE BREAK Bit
This read-only bit indicates the state of the RBRAKE output pin
1 = The RBRAKE output pin is active. Braking is in progress.
0 = The RBRAKE output pin is inactive and no braking is in progress.
