Edition 6.0 Chapter 4. Station Adjustment [5/28]
4.4 Head A Check Sensor
Adjustment
1. Adjust the position of the sensor bracket so that the head “A” sensor turns OFF between 318
to 320 degrees.
2. Note that the target clearance between the sensor and the helical gear is > 0.5mm.

4.5 PQ, FQ, RQ-axes Timing Belt Tension
Equipment Checklist:
1- 5mm T-wrench
1- 5mm L-wrench
1- 8mm spanner
1- Tension Meter
1. Use a tension meter to measure the tension of the 2
nd
, 8
th
and 10
th
station timing belts. The
target values are shown below:
Station 2 PQ 220 +/- 5 Hz
Station 8 FQ 242 +/- 5 Hz
Station 10 RQ 214 +/- 5 Hz
4.6 PQ, FQ, RQ-axes Calibration Data Setting
(0.05 deg/pulse)
1. Note that this adjustment should be performed with the servo power OFF.
2. Before setting the Calibration Data, the tension of the timing belts must be set.
3. Use the jigs below to measure the origin positions of PQ, FQ and RQ. The common jig is
suitable for measuring the origin positions of all three axes.

4. Confirm that the ”A “ shaft assembly is properly aligned, then place the relevant jig on shaft A.
5. The origin position of each station should be measured at 200 degrees. When rotating the cam
with a jig attached, ensure the jig does not interfere with neighboring shafts.
6. Use a dial gauge on the X or D axis to find the origin position of PQ, FQ & RQ. The origin position
Calibration Data should be within 0 +/- 500 pulses. At first, rotate the axis to zero pulses and then
align with the jig.
7. Once the origin position is established, input the Calibration Data by performing the following
commands:
Press: [Maintenance] → [Calibration] → [Origin Pos Offset] → [PQ], [FQ], or [RQ] → [Set].
8. Finally, receive the Calibration Data to the host PC.

1. Select a shaft with an average stroke amount (mid-shaft).
2. Set a gap of 5mm between the nozzle origin sensor and the clutch head by moving the fiber
sensor in or out.

6. Set the sensor amp to D-ON.

7. Set the mode switch to SET.
8. Press the tuning button once when the beam is in the center of the nozzle origin hole.
9. Rotate the shaft until the beam is away from the hole and focused on the clutch itself. Press the
tuning button one more time and set the mode switch to run.
10. Check to confirm that the amplifier reads 0 when the beam is focused on the center of the hole
and 9 when focused elsewhere on the clutch.
11. Confirm sensor operation using the I/O:
