CHAPTER 2 OPERATIONS AND TIMING
3. Controlling the guide bar swing motor (M3)
The circuit diagram in Figure 2-510 shows the control circuit for the guide bar swing motor
(M3).
The guide bar swing motor is a 2-phase stepping motor.
The sorter controller PCB sends drive pulses (GBMPA, GBMPA*, GBMPB, and GBMPB*)
to the motor driver.
The motor driver controls the output timing of the pulse signal A, A*, B, and B* according to
each signal, thereby switching ON and OFF the guide bar swing motor (M3) and its rotating
direction.
While the guide bar swing motor (M3) is at the hold condition, the output of the pulse signal A,
A*, B, and B* is fixed.
