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
