1.6 Z-Axis Adjustments
Procedure:
1. Before performing Z-axis adjustments, it is necessary to adjust the Z-axis
timing belt tension. Ensure to adjust where the belt is longest for an
accurate result (see below.)
2. Loosen the bolts which secure the mechanical lock in order to separate
the motor and the table. Verify that neither of the OT sensor beams are
blocked by the dogs.
3. Lower the gain(Pn100) from 70 to30 (CP732E only).
4. Inch or manually adjust the Z-axis to -900 pulses.

5. Insert a 0.2 mm (100 pulses) feeler gauge under the mechanical stopper
on the front side of the machine, then manually lower the Z-axis until the
stopper makes contact with the feeler gauge. Let the Z-axis rest at the
point at which there is no further movement. Tighten the bolts of the
mechanical lock (Torque = 1 N.m). Remove the feeler gauge and confirm
that the minus mechanical stopper position is -1000 pulses ± 50. Return
the gain setting on the CP-732E to 70.
6. Inch the Z-axis to -500 pulses and adjust the - OT dog to trigger the
sensor at this point.
7. Set the value for -OT as the software limit in the machine’s calibration
data using the following commands:
[MAINTENANCE] → [CALIBRATION] → [TRAVEL LIMITS] → [MIN
LIMIT POS.].
8. Move the XY-table near the OUT loading position and raise the Z-axis
until it reaches the plus mechanical stopper. Confirm that this value is
16850 ~ 17350 pulses (CP-742E(ME): 24200 ~ 24700pulses).
9. Inch the Z-axis to ZL Upper + 300 pulses(CP-742E(ME): 350 pulses)( (see
chapter 2, “Loading Position Adjustments”), and adjust the + OT dog to
activate the sensor at this point. Using the I/O, confirm that the + OT
sensor activates at ZL Upper+ 300 ± 50 pulses (CP-742E(ME): ZL Upper+
350 ± 50 pulses).
10. Move the axis to the point where the + OT sensor activates and set this
value as the software limit in the machine’s calibration data using the
command operation:
[MAINTENANCE] → [CALIBRATION] → [TRAVEL LIMITS] → [MAX
LIMIT POS.].
