2.2.4 Loading Position Sensor Adjustment Procedure: 1. Adjust the bracket so that the sensor beam is centered directly over the reflective silver area of the sensor dog. 2. Ensure that there is a space of 11.5 mm between…

2.2.3 Measuring ZL_IN, ZL_OUT

Procedure:

1. Adjust the conveyor width to hold a 356 x 254 mm board (or similarly

large board). CP-742E(ME): 457 x 356 mm

2. Load the board onto the main conveyor, then move the OUT-carrier to

the advance limit position.

3. Inch the Y-axis to the YL_OUT position and the X-axis to the XL_OUT

position.

4. Using the I/O, open the out carrier [MAINTENANCE] - [I/O CHECK] -

[STANDARD] - [Y083 OUT-CARRIER OPEN], and the main lifter

clamper [Y044 MAIN-LIFTER UNCLAMP].

5. Manually raise the Z-axis to the 16250 pulse position (CP-742E(ME):

23100 pulses) and then using the I/O, close the out carrier [Y082 OUT-

CARRIER CLOSE]. Raise the Z-axis higher if the carrier fails to fully

clamp the board. Lower the Z-axis until there is no contact with the OUT

carrier.

6. Attach a dial gauge to the surface of the board, as close to the rear carrier

as possible, then set the dial to zero. Slowly raise the Z-axis until the

main lifter comes into contact with the OUT carrier and the dial gauge

displays 0.5 mm. Note the motor pulse count at this point. Repeat this

step for the front carrier and again note the motor pulse count.

7. The larger of the two noted values is ZL_OUT.

8. Repeat the procedure for ZL_IN.

9. Verify that both loading position sensors are triggered when the table is

in it’s respective position.

10. Record both positions in calibration data using the following commsnds:

[MAINTENANCE] → [CALIBRATION] → [LOADING POS]

Note: +OT adjustment should be performed now that the ZL position has been ascertained.

2.2.4 Loading Position Sensor Adjustment

Procedure:

1. Adjust the bracket so that the sensor beam is centered directly over the

reflective silver area of the sensor dog.

2. Ensure that there is a space of 11.5 mm between the sensor and the dog.

3. Confirm the sensor reaction at the I/O, XOBF XY-Table Inside Loading

Position Check, X0DA XY-Table Outside Loading Position Check.

4. Move the table to the respective loading position and inch 250 motor

pulse counts in the plus and minus X and Y directions. Note the four

values displayed on the sensor amplifier at each of theses points and set

the highest one as the amplifier sensitivity threshold level.

5. To adjust the amplifier, move back to the loading position once more,

ensure that switch 1 is set to “L”(light ON), and then set switch 2 to

“ADJ”.

6. Use the up and down buttons (3 and 4) to adjust the amplifier reading to

the previously noted threshold value and return switch 2 to “RUN”.

7. Inch away from loading position then move back to confirm that the

LED (5) comes on.

2.3 Z-Axis Calibration Data Adjustments

2.3.1 Middle Loading Position ML

Procedure:

1. Take the lower value of ZL_IN and ZL_OUT and deduct 9250 pulses

(18.5 mm). (CP-742E(ME): 14000 pulses (28 mm))

e.g. CP-732E

ZL_IN = 15750

ZL_OUT = 15725

Middle Loading Position ML = 15725 - 9250

= 6475 pulses

Record this motor pulse count.

e.g. CP-742E(ME)

ZL_IN = 23300

ZL_OUT = 23275

Middle Loading Position ML = 23275 - 14000

= 9275 pulses

Record this motor pulse count.

2. Move the Z-axis to that position (ML), then move the X-axis from

XL_OUT to XL_IN by hand, verifying that there is no interference

between the OUT-carrier cylinder/nut and the table piping.

2.3.2 Upper Limit Sensor 1

1. The upper limit sensor dog should be adjusted to trigger when the Z-axis

is at ML-125 ± 50 pulses.

2. Confirm the position of the dog using the I/O, [MAINTENANCE] - [I/O

CHECK] - [STANDARD] - [X05C Table Loading Height Check].

2.3.3 Rail Clamper Adjustment

1. Adjust the rail clamper air valve to activate the clamper at ZL(lower) -

650 ± 50 pulses.

Loosen and adjust up or down
