1. Check that the coupling is loose, then set the Y axis pulse counter to 75000 pulses.
2. Pull the Y-axis up against the (155mm) (Fig. 4) Y-axis jig. (Jig No: DCPJ0720)
3. Make sure the coupling is in the center of the shaft and temporarily half lock it with 3mm wrench
and pipe.
4. Remove the jig.
5. Pull the Y-axis to the – mechanical stopper.
6. Record the Y pulse count at the – mechanical stopper.
It must be close to – 2500, if not then offset the value and
repeat the steps above.
7. Finally, lock the coupling bolts with a 3.4N.m torque wrench.
8. Check the alignment of the OT sensor flags and OT sensors.
9. Set the – OT sensor so that it turns ON 2000 pulses away from

the – mechanical stopper. It must be – 500 +/- 100 pulses.
10. Move the Y-axis 500 pulses away from the position where the – OT
sensor turns ON and set the Calibration Data. (Min Limit Position)
Press: [Maintenance] → [Calibration] → [Travel Limits] → [Minimum Limit Y]
11. Move the XY table to the + mechanical stopper and record the pulse count at this position. It must
be 195000 +/- 1000 pulses.
12. Set the + OT sensor so that it turns ON 2000 pulses back from the + mechanical stopper. It must
be 193000 +/- 1000 pulses.
13. Move the Y-axis back 500 pulses from where the + OT sensor turns ON and set the Calibration
Data value. (Max Limit Position)
Press: [Maintenance] → [Calibration] → [Travel Limits] → [Maximum Limit Y]
14. Table 4 lists the Y-axis Calibration Data and physical data reference values:

3.4 X and Y Axes Backlash Check
1. Place a (0.002mm) dial gauge against the X-axis of the XY table (Fig.5). Make sure the servo
power is ON, push the XY table left and right by hand to check the amount of backlash.
(Tolerance: 0.010mm.)
2. Check the Y axis in the same manner. Make sure the servo power is ON, push the XY table
back and forth to check the amount of backlash. (Tolerance: 0.010mm.)

3. If the amount of backlash is out of tolerance, check the following 2 areas.
a. Ball nut
b. Ball screw bearings

3.5 X/Y Table Squaring Check
Check the squaring of the X/Y table using the jig plate.
CP-732/733E (Jig No.: ADCPJ8301)
CP-742/743(M)E (Jig No. ADGPJ8060)
1. Align the jig in the Y direction to zero using a dial gauge.
2. Indicate the jig face in the X direction to check table squaring.
(Tolerance: 0.015 / 239mm)

3.6 Reference and Adjustable Pin Alignment Check (CP-742/743(M)E)
Check the alignment and play of the tooling pins as follows.
1. The diagram below shows the tooling pin configuration for the CP-742/743(M)E.
Reference pin B
Reference pin A
Secondary pin B
Secondary pin A

2. To check the alignment of the four pins, place a dial gauge (0.002mm) against reference pin A
and set it to 0.
3. Inch the X/Y table in the X direction and measure the alignment of the three other pins in
relation to reference pin A .
4. Measure at the points indicated in the tables below:
Measuring Point (mm) Max 370 270 170 70 Reference pin A
Center Position 0
Backlash Value
Secondary Pin A:
Center Position Tolerance: +/- 0.050mm. Backlash Tolerance: 0.040mm.
