4. While observing the dial gauge, rotate the cam axis in the forward direction to raise the nozzle UP/DOWN rod. Adjust the sensor ’ s mounting position so that the sensor switches OFF (I/O INPORT X03F ST11 DN POS switch…

Nozzle DOWN Limit Sensor

Note: When performing the DOWN limit sensor adjustment after the UP limit sensor adjustment,

remove the dial gauge from the machine to avoid interference between the dial gauge and

the cam lever.

1. Set the cam axis to the 180-degree position.

2. Execute the following I/O commands to pull in the ST 11 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 180-degree position, and the nozzle

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

limit sensor is ON (I/O INPORT X03F ST11 DN POS is ON).

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

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

the sensor switches OFF (I/O INPORT X03F ST11 DN POS switches OFF) when

the rod has been raised 0.3 to 0.4 mm.

5. Adjust the sensor’s mounting position by loosening the sensor lock screws and

sliding the sensor in the front/back directions.

3.5.3 Nozzle Vacuum Off

The nozzle vacuum goes from ON to OFF with the movement of the mechanical valve at

station 11. Vacuum pressure inside the nozzle releases for part placement when the

valve closes. Ensure the part is placed on the production board.

Nozzle Vacuum Lever Adjustment

1. Adjust the valve ON/OFF operation at the reference head.

The reference head is ascertained by raising each spool as shown in the figure

above and measuring its height. The lowest head is used as the reference.

2. Select [SET] - [MANUAL] - [I/O] and then press the EMERGENCY STOP button

to take the 200V down to 100V.

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.

3. Set the cam angle to 0°, then turn on the nozzle vertical movement solenoid (Y028

PLACE SOL ON) for the nozzle at station 11 to work the lever.

4. Use the cam handle to rotate the cam to 200°.

5. Adjust the height of the bracket so that the distance between the spool and the

lever is 0.05 ~ 0.1 mm (This measurement can be made with a feeler gauge).
