13-4-2. CPU Board (40107372)
[Functions]
This is a circuit board that controls the equipment totally. This circuit board is connected to other
circuit boards by the Compact PCI (hereafter referred to as “cPCI”) bus.
[DIP switch settings]
This CPU board is used with the dip switch settings made before shipment.
[Meaning of LED]
PW: Shows the power supply status using the lighting status.
Lit in green.............Normal operation status
Flashing in green...Standby status
Off..........................Shutdown status
HDD: Flashes in green when accessing to the SSD.
RESET: Push switch with LED. This switch functions as the reset switch. The LED functions as
the Power ON LED.
Do not press this switch.
Lit in green.............Shows that the power is supplied.
Off..........................Shows that the power is not supplied.
[Replacement of battery]
A backup battery is mounted on the CPU board to save the BIOS settings.
Replace the battery at reference intervals of 5 years.
After the battery has been replaced, it is necessary to set up the BIOS.
[Adjustment items after replacement]
After the CPU board has been replaced, it is necessary to set up the BIOS.

13-4-3. Position Board (40044540)
[Functions]
This POSITION board is applicable to the CPCI bus and intended to control servomotors
through the SSCNET III, Mitsubishi Electric’s high-speed synchronous communication network.
The POSITION board can control up to 32-axis servomotors per board.
The POSITION board is connected to the servo amplifier of each axis through daisy chain
connections of optical fiber cables.
c A command is received from the CPU board software to control the XYZθ-axis servomotor.
d The home position sensor and limit sensor of each axis are detected.
e An alarm is detected that occurs in the servo amplifier or magnescale.
f The emergency stop switch is detected to stop the XY-axis and Zθ-axis.
[Switch settings]
Since the FX-3R uses two position boards, the settings may vary depending on the position
board, which has been replaced.
The settings are shown below. ( portions show the switch positions.)
Change the settings
with the POS1 or
POS2 switch.

∗ POS1 switch is used for the left station while POS2 switch is used for the right station.
[Meaning of LED]
Operation indicator LED (Green): Lights up when the power is turned ON, flashes when the
system is started up, goes off when the power is shut-down.
Error indicator LED (Red): Off during normal operation, Lights up if an error occurs.
[Adjustment items after replacement]
There are no particular adjustment items.
