in the forward direction; +5V will cause it to start in the reverse direction. The CN
command is used to define the polarity of the home input.
2. Upon detecting the home switch changing state, the motor begins decelerating to a stop.
3. The motor then traverses very slowly back until the home switch toggles again.
4. The motor then traverses forward until the encoder index pulse is detected.
5. The DMC-3425 defines the home position (0) as the position at which the index was
detected.
