B. Controlling the Delivery Motor1. OutlineThe delivery motor (M6) is a 2-phase stepping motor.The five types of signals generated by the DC controller are converted into drivepulse commands (DMA, DMA*, DMB, DMB*) by the motor drive circuit and the deliverymotor drive circuit on the motor driver 2 PCB, and are used to control the direction andthe speed of rotation of the delivery motor.Figure 6-302 is a block diagram showing the circuit used to control the deliverymotor.Figure 6-302CHAPTER 6 FIXING SYSTEMCOPYRIGHT © 1997 CANON INC.
