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.
