the main circuit contactor and the line filter. It turns the main circuit control contactor ON
and OFF using the signal for the servo power control from the machine safety I/O logic
circuit board, and supplies power (3-phase AC200/220V) to the converter.
The power supply (single phase AC200/220V) is supplied to the control power supply via
the line filter.
