3.1.1 Removing the D-Axis Motor

Procedure:

1. Turn OFF the machine power.

2. Inch the D2-table in the direction of the D1-table in order to gain access

to the motor (D1).

3. Disconnect both electrical connections to the motor.

4. Remove the two (2) Phillips head screws securing the cover over the

coupling, and take off the cover.

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 two (2) allen extension bolts (bottom) and the two (2) allen

bolts (top) securing the motor to the machine and then remove the

motor.

3.1.2 Installing the D-Axis Motor

Procedure:

1. Secure the new motor to the machine with the two (2) allen extension

bolts and two (2) 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.

3.2.1 Minus Overtravel Sensor Adjustment

Procedure:

1. Remove both feeder pallets prior to adjusting.

2. Manually move table 2 (table 1) towards the center of the axis to gain

access to the D1 (D2) motor. Remove the two (2) Phillips head screws

securing the cover over the coupling, and take off the cover. Loosen the

for allen bolts securing the coupling.

3. Temporarily remove both minus overtravel dogs, then inch the D1-

motor to 5000 (-5000 for D2) pulses. Push the D1 table against the plus

mechanical stopper (D2 against the minus mechanical stopper), and

tighten the coupling. D-axis coupling torque = M5: 8.3 N.m, M4: 4 Nm.

(CP-742E(ME): all 8.3 N.m).

4. Push the EMERGENCY STOP button, and pull the D1 (D2) table back

against the stopper again. Record the motor pulse count at this point.

5. Replace the -OT dog and adjust to activate the sensor at the point 3500

pulses back from the stopper. Record the counter value.

6. Move back an additional 500 pulses from the position at which the

minus OT sensor activates and set this position in calibration data as the

D1 Max Limit Pos (D2: Min Limit Pos). using the following commands:

[MAINTENANCE] → [CALIBRATION] → [TRAVEL LIMITS] → [MAX

LIMIT POS.] (D2: [MIN LIMIT POS]).

7. Confirm the sensor reaction using the I/O commands:

SX042 D1 AXIS -OT

SX04A D2 AXIS -OT

D1 - OT sensor

(SX042 D1-AXIS -OT)

D2 -OT sensor

(SX04A D2-AXIS -OT)
