3.15 D-axis Interference Prevention Sensor Adjustment
1. Ensure that the sensor face is parallel to the D-axis ball screw.
2. Set the amplifier volume on the sensor 1 to 1.5 scales from where the beams click. (Middle of Min
and Max.)
3. Zero set the D1 and D2 tables, then move both tables to around the center of the machine.
4. Manually rotate the ball screw so D1 contacts D2. Move D1 2700 pulses (23mm) back from this
position.
5. Adjust the flag so the interference prevention sensor activates when the clearance
between both tables is 2700 pulses. (Tolerance: 2700 +/-25 pulses)

6. To set the travel limits (Min Limit D1) and (Max Limit D2) follow the procedure below:
a. Zero set both device tables.
b. Manually move D1 toward D2 (D2 is at 0 pulses) until the interference prevention sensor
triggers. Move D1 back 117 pulses (Min Limit Pos. D1) and enter the pulse count at the host
PC.
c. Position D1 to 0 pulses, move D2 toward D1 until the interference prevention sensor triggers.
Move D2 back 117 pulses (Max Limit Pos. D2) and enter the pulse count at the host PC.

3.16 D-axis Pallet Flatness Measurement
1. Flatness of the top plates on the pallets is important to maintain consistent pick up. Set up two dial
gauges as pictured and indicate the top surface of the feeder plate at the positions illustrated in
Fig.34. (Tolerance: within 0.1mm)
2. If the flatness measurement is out of tolerance, contact Fuji for further instructions.

3. Set a dial gauge and block on the machine base and check the flatness from A to B.
(Tolerance: within 0.05mm)
3.17 Cam Box Positioning Check
1. Attach the positioning jig onto the A Shaft and turn the Pick-up valve ON.
2. Position the A shaft at station 1 and set the cam to 200 degrees.
3. Install the cam box alignment jig on the D1 table.
(Tolerance: 0 to + 0.05mm)
4. Check the cam box position at slots 3 & 68 of D1 & D2
3.18 Pick up Position Calibration
1. Attach the positioning jig onto the A Shaft. (Jig No.:ADCPJ8130)
2. Set the “Pick up Position” jig on the D1/D2 table at slot No.1. (Jig No.:Z9913AWPJ9330)
3. Turn the Pick-up valve ON and set the cam to 170 degrees at Station 1.
4. Balance the dial gauge on both sides of the positioning jig in the X-direction.
When the gauge is balanced on each side, this becomes pick up position D1/D2.
5. When balanced, enter the pulse count into the proper at the host PC.
