1.3.1 Removing the Y-Axis Motor

Procedure:

1. Turn OFF the machine power.

2. Remove the front cover from the machine in order to gain access to the

motor.

3. Retract both the IN and OUT carriers, and widen the machine’s conveyor

rails to allow better access to the machine.

4. Push the motor away from the stopper and remove the two (2) Phillips

head screws securing the cover over the coupling.

5. Loosen the coupling on the motor side to separate the motor from the

ball screw (refer to the figure below).

6. Disconnect the two (2) electrical connections from the motor.

7. Remove the four (4) allen extension bolts securing the motor to the

machine and then remove the motor.

1.3.2 Installing the Y-Axis Motor

Procedure:

1. Secure a new motor to the machine with the four (4) allen bolts.

2. Reconnect the two (2) electrical connectors to the motor.

Note: Do not tighten the coupling at this stage.

Notice

Note that as the CP-7 utilizes absolute encoders on all axes, it is no

longer necessary to boot up the machine in Mechacheck mode when

performing motor adjustments.

Edition 2.0 1-13 CP-7-series Level 3 Tutorial

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.
