6. Select [SET] → [SERVO] to view the Z-axis motor pulse count and then manually inch the Z-axis upwards until the dial gauge reads 0.3 mm. 7. Enter the resultant pulse count into Proper data. [SET] → [PROPER] → [D1/D2/Z…

1. Z-Axis Origin Position (Zθ)

In order to offset board warpage and minute deviations in nozzle shaft placing height, Zθ, the Z-axis

reference placing height, is calibrated in order that the board rises to make contact with the part being

held by the nozzle and then pushes up a further 0.3 mm.

1.1 Zθ Measurement (CP-642)

1. Load the fiducial jig-plate onto the main conveyor as shown in the diagram below.

2. Using the inching keys, move the fiducial plate under station 11.

3. Switch the I/O (Y028 PLACE SOL ON) to ON.

4. Rotate the cam angle to 200°, ensuring that the jig-plate is situated directly

underneath the nozzle shaft.

5. With a 20 mm diameter backlight-plate facing downward, place the dial gauge

needle on the upper surface of the backlight disk and set to zero.

6. Select [SET] → [SERVO] to view the Z-axis motor pulse count and then manually

inch the Z-axis upwards until the dial gauge reads 0.3 mm.

7. Enter the resultant pulse count into Proper data.

[SET] → [PROPER] → [D1/D2/Z] → [ORIGIN] → [Zθ] → [SET].

8. Once the Zθ origin position has been registered at the machine side, ensure to

receive proper data to the host computer.

Note: When the machine is not in operation, there is nothing to prevent the XY-table damaging

the nozzle shaft at station 11. To avoid any unnecessary damage, always position the jig-

plate under station 11 when the cam angle is at 0°.

1.2 Zθ Adjustment (CP-643E)

Repeat the procedure for the CP-643E using the jig-plate below as opposed to the fiducial

jig-plate.

Note: The “-0.3 mm” spacer should be used for Z

measurement

2. Placement Accuracy Measurement

PAM, an acronym for Placing Accuracy Measurement, is a measurement procedure used to calculate

and adjust the machine’s placing accuracy.

Note: Use of the machine for long periods without proper maintenance can reduce the original placing accuracy.

PAM can be used at such times to restore the placing accuracy to original levels.

Please verify the contents of the PAM shipping container.

Overview

When PAM is started, a correction value for Station 11 (part placing station) Proper data

is calculated, and the ST11 Proper data is re-entered and saved in accordance with this

correction value. This data is also transmitted back to the host computer (F4G or MCS).

This ST11 Proper data acts to correct mechanical positional error (due to working and

mounting error amounts), resulting in a uniform correction. X and Y direction correction

values are entered for each nozzle. As the system consists of 20 heads with 6 nozzles per

head, this results in a total of 240 Proper data input items.
