4. Place a dial gauge on the top end of the cam lever 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 (X030 ST1 CYLINDER UPPER-LIMIT is ON) at the I/O screen.

5. 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 (X030 ST1 CYLINDER UPPER-LIMIT switches OFF)

when the rod has been lowered 0.3 to 0.4 mm.

6. Adjust the sensor’s mounting position by loosening the sensor lock screw and

sliding the sensor in the front/back directions.

1.5 Mechanical Valve Switching (Station 1)

Point

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

station 1. Vacuum pressure for part pick-up forms inside the nozzle when the valve is

open.

1.5.1 Checking the Position of the Pin Bracket

1. Press the EMERGENCY STOP button to turn off the 200V power, leaving only the

100V power on.

WARNING

Always be sure to cut off the 200V power before carrying

out any work.

2. Ensure that distance A (as seen in the figure below) is 8.9 mm for all heads. Use a

special jig (Z9526DCPJ0371) to check this distance.

1.5.2 Valve Switching Lever Height Adjustment

This adjustment should be performed on the reference head after completing

adjustments to the vertical movement of the nozzle. (Refer to 1.4 “Nozzle Vertical

Movement During Pickup” for details.)

The reference head can be identified by its height. All heads are measured with spools

lifted, and the lowest one is referred to as the reference head.

1. Press the EMERGENCY STOP button to take the 200V down to 100V.

WARNING

• Always be sure to cut off the 200V power before carrying

out any 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.

2. Adjust the position of the lever bracket so that the distance from the pin bracket is

12 mm.

3. With the Y030 ST1 PICKUP SOL DISENGAGED ON, use the cam handle to rotate

the cam to 170°.
