Error detection
[1] When the main motor drive signal (MAIN_M_ON) goes '1', the main motor starts to rotate.
[2] When the main motor rotates, clock pulse signals (MAIN_M_FG) are generated. If the DC controller PCB detects
an error in clock pulse signals, it will indicate "E010" in the control panel.
