3.3 Y-axis Zero setting (0.01mm/pulse)
1. Ensure that the Y-axis motor is NOT inclined or tilted.
2. Make sure that the zero setting and OT sensors are not blocked by the flags.
3. Carry out Y-axis zero setting by mechanical check mode. ( Y-axis motor rotates)
4. In Mecha-check mode, complete zero setting by blocking the zero set sensor with a scale.
5. Set the servo counter value to 22000 pulses.
6. Place the coupling tightening jig (211mm) between the Y-axis mechanical stopper and Y-axis
base. Tighten the coupling bolt to a torque value of 7Nm.
7. Press the emergency stop button and bring the Y-axis to the minus mechanical stopper. Record
the servo counter value. (To bring the value close to – 500 pulses, offset the 22000 pulses in
step 5.)
8. Set the servo counter to plus 1000 pulses. Adjust the flag to turn the zero set sensor ON at this
position. Record the servo counter value.
9. Adjust the flag to turn the minus over travel sensor ON when bringing the flag 250 pulses back
from the minus mechanical stopper. Record the servo counter value.
10. Record the servo counter value when the table is in contact with the plus mechanical stopper.
Adjust the sensor position to turn the plus over travel sensor ON when bringing the flag 100
pulses back. Record the servo counter value.
11. Confirm sensor reaction by I/O.

12. Set the software travel limits as follows:
Move the Y-axis back 100 pulses from where the + OT sensor turns ON and set the proper
value. (Set the Max Limit Position at the host PC)
13. Move the Y-axis forward 100 pulses from where the – OT sensor turns ON and set the proper
value. (Set the Min Limit Position at the host PC)

3.4 X and Y Axes Backlash Check
1. Place a (0.002mm) dial gauge against the X-axis of the XY table (Fig.4). 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
backwards and forward 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.
(Jig No.: Z9913AWPJ9560)
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)
