4. Move the area for the removed axis to station 11, then use I/O (Y028 PLACE SOL

ON) to operate the lever.

5. Set the cam angle within the range shown below, and position the dial gauge as

shown in the figure above.

• CP6-4000 = 313° ~ 53°• CP6-5000 = 308° ~ 75°

6. Adjust the rod so that there is 0 ±0.03 difference between the slider groove and the

fixed groove in the cam.

7. Reattach the nozzle shaft assembly in the original location.

Using the clutch alignment jig, reverse the removal procedures to attach the

assembly.

3.5.2 Adjusting the Nozzle UP Limit and DOWN Limit Sensors

The nozzle UP limit and DOWN limit sensors which detect the height of the nozzle

UP/DOWN rod are mounted inside the cam box. Adjust the mounting positions of

these sensors so that they switch ON when the nozzle is at its UP limit and DOWN limit

positions.

WARNING

• Turn off the 200 V servo power before carrying out this work.

• Exercise extreme caution when working on the machine if the cam is

not at its origin (0 deg.). Recoil of the cam axis can endanger the

operator.

Nozzle UP Limit Sensor

1. Set the cam axis at the 0-degree position.

2. Execute the following I/O commands to pull in the ST11 placing stop cylinder

(located in the cam box):

[SET] - [MANUAL] - [I/O] - [Standard I/O] - [OUTPUT] -> Y028 PLACE SOL ON

The cam lever will then follow the cam axis.

3. Place a dial gauge on the nozzle UP/DOWN rod and set the gauge reading to “0”.

In this condition, the cam axis will be at its 0-degree position, and the nozzle

UP/DOWN rod will be at its UP limit position. Verify that the nozzle UP limit

sensor is ON (I/O INPORT X06B ST11 UP POS is ON).

4. While observing the dial gauge, rotate the cam axis in the forward direction to

lower the nozzle UP/DOWN rod. Adjust the sensor’s mounting position so that

the sensor switches OFF (I/O INPORT X06B ST11 UP POS switches OFF) when

the rod has been lowered 0.3 to 0.4 mm.
