• Rotational direction control
• Motor speed control
The forward and reverse rotational direction is controlled by FWD (pin 16) and REV (pin 15) inputs.
Conditions are as follows.
- 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
- Motor torque is maximum when pin 19 is open.
