The CH1/3 exclusive mode constitutes one DCM motor and the electrical current in the OUT1A → OUT3A direction is assigned as “forward direction”. Note 7. The CH2/3 exclusive mode constitutes one DCM motor and the electrical current in the OUT2A → OUT3B direction is assigned as “forward direction”. Note 8. The CH3/5 exclusive mode constitutes one DCM motor and the electrical current in the OUT3A → OUT5A direction is assigned as “forward direction”. Note 9. The CH13/23 exclusive mode constitutes one STM motor and the electrical current in the OUT1A OUT3A and OUT2A → OUT3B direction is assigned as “forward direction”. Figure 3.
