1.4 Y-Axis Adjustments
Procedure:
1. Ensure that the Y-axis is not inclined or tilted.
2. Either manually, or by means of the inching keys, move the motor until
the motor pulse count reads 75000 pulses (CP-742E(ME): 110000).
Note: It is necessary to offset by 75000(110,000) pulses in order to achieve the desired result at
stage 5.
3. Place the 155 mm spacer between the Y-axis minus mechanical stopper
and the Y-axis base (refer to the diagram opposite). At this point, tighten
the coupling bolts with 3.4 N.m torque (CP742E(ME): 8 N.m).
4. Push the EMERGENCY STOP button and pull the XY-table back against
the minus stopper. Record the motor pulse count at this point. The
counter should read -2500 ± 100.
5. Adjust the - OT dog so that the sensor activates when the Y-axis is
moved back 2000 pulses from the mechanical stopper. Take a note of the
motor pulse count at this point.
6. Move the Y-axis back 500 pulses from the above noted position and set
this value as the software limit in the machine’s calibration data using
the command operation:
[MAINTENANCE] → [CALIBRATION] → [TRAVEL LIMITS] → [MIN
LIMIT POS.].
7. Push the XY-table to the plus side mechanical stopper and record the
motor pulse count.

8. Adjust the sensor position to activate when the Y-axis moves 500 pulses
back from the stopper. Record the motor pulse count at this time, and
adjust the +OT sensor to trigger at this point.
9. Move the Y-axis back 500 pulses from the above noted position 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.].
Note: Be careful when adjusting the CP-742ME Y-axis as the distance between the (+)
mechanical stopper and the (+) OT sensor is only 500 pulses.
10. Confirm the above adjustments at the I/O using the following
commands:
[MAINTENANCE] → [I/O CHECK] → [SERVO] → [INPUT].
