Main P.C. board

Secured to the side. This is the P.C. board that controls sewing machine operation.

PMD P.C. board

Secured to the base plate. This P.C. board drives the pulse motors and solenoids.

Power supply motor P.C. board

Secured to the rear. This P.C. board generates the voltages that are required for control, and drives the main shaft motor. There are 8 fuses on this P.C. board.

DC fan motor

This fan cools the inside of the control box.

The filters at the air intake slots in the cover and base plate should be cleaned about once a month.

Conversion transformer (Two types are used depending on the power supply voltage specifications.) This breaks down the power supply voltage into the voltages that are required for control operations.

NF P.C. board (European destinations only)

This eliminates the electrical interference that is generated by the power supply fan.

Panel P.C. board

Secured to the inside of the operation panel. This P.C. board is used for displaying the sewing machine status and for input operations.
