3.9 Z -axis Zero Setting (0.002mm/Pulse)
Note: The table must be level before making Z-axis adjustments.
1. Set the tension of the Z-axis timing belt as follows:
CP-643E = 100 +/- 2 Hz.
Measure the belt at a position where the span is the longest (front or back)
2. Remove the minus OT flag for the Z-axis.
3. Loosen the mechanical lock at the Z-axis drive pulley. (make sure the motor shaft turns freely)
4. In Mecha-check mode, complete zero setting by blocking the zero set sensor with a scale.
5. Inch the Z servo count to – 900 pulses.
6. Lower the Z-axis toward the (–) mechanical stopper and insert a 0.2mm feeler gauge between
the stopper and base of the table.
8. Lock the four securing bolts for the mechanical lock with a 1N.m torque wrench.
9. Check that the pulse count is close to – 900 with a 0.2 gauge between the minus stopper and
table.
10. Attach the – OT flag with the pulse count at – 500 pulses.
11. To set the software travel limit, find the pulse count where the minus OT sensor just turns ON.
Set the Z Min limit position at the host PC.
Note: Set the Maximum limit after the loader adjustment has been completed.
(Refer to the tables in step 13 for details)

3.10 Back-up Plate Height and Flatness Adjustment
1. After zero-setting the Z-axis, raise the table to 5000 pulses. Place the height
adjustment jig on the backup plate.
2. Adjust the 4 bolts so the top surface of the jig and clamper base are equal.
3. Note: When changing the Z-axis position, the spring force to the plate changes
and the jig’s height will slightly differ. Please pay attention when adjusting.
(Adjust it within range so that the Z-axis and backup plate are synchronized.)
4. Flatness tolerance ----- less than 0.1mm
(There are 4 adjustment bolts. It is better to set one height as reference and measure with a
dial gauge.)
3.11 Back-up Pin Interference Prevention Sensor Adjustment
1. Adjust the 4 flags so the sensors will turn ON, when the clearance between the Y-table and the
backup plate is 2mm. (Set the flags so the 4 sensors activate within 50 pulses of each other.)
2. Check the sensor reaction in I/O.
