1.4 Controlling the Main Motor (M2)
1.4.1 Outline
The functions of the main motor control circuit are as shown in the following table, and
its block diagram is shown in the following figure:
1. When the main motor drive signal (MMON) goes ‘1’, the main motor starts to rotate.
2. When the main motor rotates, clock pulse signals (MMFG) are generated. If the DC
controller PCB detects an error in clock pulse signals, it will indicate “E010” in the con-
trol panel.
