Controlling the Reversal Motor (M1)
The following is the control circuit diagram of the reversal motor (M1). The reversal mo-
tor is a 4-phase stepping motor, and the circuit is used for the following:
• Turning on/off the motor.
• Controlling the rotation direction of the motor.
• Controlling the rotation speed of the motor.
