CHAPTER 2 OPERATIONS
Description
Controls motor rotation.
Controls motor drive.
Monitors motor operation.
3. Controlling the Delivery Motor (M5)
Figure 2-231 shows the circuit used to control the delivery motor (M5). The delivery motor is a DC
motor, and the circuit has the following functions:
Turning on and off the motor.
Controlling the rotation speed of the motor.
Figure 2-231
The CPU (Q1) on the ADF controller PCB sends the motor rotation speed signal (EJMPWM*) to
the drive control assembly, which in response generates the motor drive signal (EJMD*).
The motor rotation signal (EJCLK) occurs when the motor rotates, used by the CPU to monitor the
operation of the motor.
