Error detection
[1] When the main motor drive signal (MTRON) goes '1', the main motor starts to rotate.
[2] When the main motor has started to rotate and reached a specific revolution, the motor
causes the main motor rotation detection signal (MLOK*) to go '0'. If the DC controller
PCB detects an error in the rotation detection signal, it will indicate 'E010' in the con-
trol panel.
