B. Controlling the Delivery Motor

1. Outline

The delivery motor (M6) is a 2-phase stepping motor.
The five types of signals generated by the DC controller are converted into drive
pulse commands (DMA, DMA*, DMB, DMB*) by the motor drive circuit and the delivery
motor drive circuit on the motor driver 2 PCB, and are used to control the direction and
the speed of rotation of the delivery motor.
Figure 6-302 is a block diagram showing the circuit used to control the delivery
motor.
