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°.

4. Adjust the height of the bracket so that the distance between the lever and the pin

is 0.6 mm.

5. Return the cam angle to 0 degrees. Switch on the 1st nozzle UP/DOWN solenoid

valve in order to work the cam lever.

Check the servo counter to verify that the Proper data (PICK UP POS. NZ) is at the

pick-up height (approx. 4000 pulse position).

6. Use the cam handle to rotate the cam to 170 degrees.

7. Ensure that the clearance of the pin from the bracket is within the range of 0.5 to

1.0 mm after the pin has been raised by the lever.
