Note: In the case of the CP-742E(ME), it is not necessary to use a jig. After loosening the coupling, inch the motor to 2500 pulses, push the table against the stopper and tighten the coupling bolts with 14 N.m torque. C…

1.2 X-Axis Adjustments
Procedure:
CP732E Only
1. Temporarily remove the -OT sensor dog prior to performing the X-axis
adjustments.
2. Either manually, or by means of the inching keys, move the motor until
the pulse count reads -75000 pulses.
3. Place the 155 mm spacer between the X-axis plus mechanical stopper and
the X-axis base (refer to the diagram below). At this point, tighten the
coupling bolts with 7 N.m torque.
4. Remove the spacer and push the X-axis against the plus side mechanical
stopper. Record the motor pulse count at this position.

5. Adjust the - OT dog to activate the sensor when the X-axis is moved back
2000 pulses from the stopper. Record the motor pulse count at this
position.
6. Move the X-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.].
7. Push the table against the minus side mechanical stopper and record the
motor pulse count at this position.
8. Adjust the + OT dog to activate the sensor when the X-axis is moved
back 2000 pulses from the stopper. Record the motor pulse count at this
position.
9. Move the X-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.].
