Controlling the Reversal Motor (M1)
Figure 2-276 shows the circuit used to control the reversal motor (M1). The belt motor is a 4-phase
stepping motor, and the circuit has the following functions:
Turning on and off the motor.
Controlling the direction of motor rotation.
Controlling the speed of motor rotation.
Figure 2-276
The CPU (Q1) on the ADF controller PCB sends various motor control signals to the reversal motor
driver PCB. In response, the reversal motor driver PCB controls the respective motors to suit the incom-
ing signals.
