• Rotational direction control
The forward and reverse rotational direction is controlled by FWD (pin 16) and REV (pin 15) inputs.
Conditions are as follows.

• Motor speed control
- The motor speed is proportional to the differential voltage between the pin12 (DO2+) and the pin13 (DO2−).
- By applying the voltage to the pin19 of CTL, the motor speed can be controlled and it is linearly proportional to the
applied control voltage.
Motor torque is maximum when pin 19 is open.
