Main
P.
C.
board
Secured to the side. This PCB serves to control machine operation.
PMD
P.
C.
board
Secured to the bottom. This PCB drives the pulse motor and solenoids.
Power
supply
motor
P.
C.
board
Secured to the back. This PCB generates the voltages that are required for each conttol operation and drives the main shaft
motor.
Eight fuses are mounted on this
PCB.
DC
fan
motor
The DC fan motor serves as a fan to cool the inside
of
the control box.
The filters
at
the ventilation holes in cover and the base plate should be cleaned about once a month.
Conversion
transformer
(Two types are available depending on the power supply voltage specifications.)
Steps-down
t~e
power supply voltage and generates the voltages that are required for each control operation.
NF
P.
C.
board
(For
Europe)
Eliminates electrical noise that is transmitted along the power supply line.
Panel
