SCM3 Board (40114496) Laser Board for FMLA (KE-3020VR Only)

This board controls and calculates the sensor (FMLA) for centering of the part.
The board interfaces with the host CPU through RS-232C. The sensor is connected with the
coaxial cable including the power supply line through the dedicated serial communication.
Furthermore, the encoder signal of the θ-motor necessary to measure the part position is input
from the Zθ-driver.

14-3-10. S-Light Control (40108607)

This board turns on or off each light of the VCS unit installed on the base frame and adjusts the
light quantity. Additionally, when an optional high-resolution camera is selected, the board
drives the light position change air cylinder and reads the position detection sensor.

14-3-11. Feeder Board (40047560)

(1) Drives the ATC open/close solenoid valves and reads the check sensor.
(2) Reads the feeder float sensor and feeder detection sensor. (Applicable to the mechanical
and electric feeder.)
(3) Reads the backup sensor and drive cylinder up sensor.
(4) Controls the LED lighting of the CAL block and vacuum ON/OFF.
(5) Reads the vacuum calibration sensor.
(6) Drives the 80-pin mechanical feeder and reads/writes the READY signal, BUSY signal, and
disable signal.
(7) Interfaces with the 80-pin electric feeder through the CAN communication.

14-3-12. S-XY Relay Board (40106795)

(1) The EMERGENCY STOP switch and limit sensor are detected to shut down the servo
power when necessary.
(2) The EMERGENCY STOP switch, limit sensor, and NEAR-sensor are detected to inform
them to the POSITION board.
(3) Signals to be input to the Operation board are read and signals to be output from the
Operation board are sent.
(4) The positive pressure detection sensor and negative pressure detection sensor signals are
read.
(5) Flash ROM is installed that stores the M/S parameters.

14-3-13. MAGNETIC SCALE Board (40095130) (XL Specifications Only)

This board relays the signals from the X-, YL-, and YR-axis linear sensor units to input them to
the servo amplifier for each axis.

14-3-14. BASE IO Board (40071680)

(1) This board controls the operation of the back up table and auto width adjustment.
(2) The board controls the driver for the transfer stepping driver motor.
(3) The board reads out the right sensor, left sensor, WAIT sensor, STOP sensor, and COUT
sensor.
