Outline of Electrical Circuitry The machine's major electric mechanisms are controlled by the microprocessor mounted on the DC controller PCB, which reads input signals from sensors and operating keys according to the instructions of the program stored in advance and sends signals used to drive motors, solenoids, lamps, and other loads as needed.

Executes constant speed rotation control. Operations The main motor M1 is a DC motor with a built-in clock pulse generator, which generates clock pulses MMCLK in relation to the rotation of the motor while the motor is rotating. Related Error Code E While the main motor drive signal is generated, the rotation of the main motor deviates from a specific number for 1 sec or more. Rotating the Main Motor at a Constant Speed The drive circuit on the motor driver PCB controls the main motor so that the phase of the frequency of the clock pulse signals MMCLK occurring when the motor rotates and that of the frequency of the reference signals match.
