8. Set the amplifier mode switch to RUN.

9. Confirm for all shafts that the amplifier display reads 0 when the clutch is correctly engaged at 200

degrees, and 9 when the clutch is NOT correctly engaged.

Note: In some cases, it may be necessary to keep re-tuning the sensor amplifier until you get

results of 0 and 9 for all shafts. If these results cannot be achieved, the clearance between

the clutch underside and the meshing check block may not be enough, or the optical fiber

connections to the amplifier may need trimming with a fiber cutter.

10. Confirm sensor operation using the I/O:

4.9 Nozzle Changer Adjustment

Follow the procedure below in order to adjust the Nozzle Change Mechanism Correctly.

There are several items for adjustment.

4.9.1 Alignment

4.9.2 Gear Backlash

4.9.3 Stroke

4.9.4 NC origin Calibration data

4.9.1 Nozzle Changer Alignment Adjustment

Figure 15

Item 1 = Stroke adjusting rod

Item 2 = UP/DOWN positioning bolts

Item 3 = Height adjusting bolt

Item 4 = Fwd/Bwd adjusting bolt

Item 5 = Fwd/Bwd positioning bolts

Item 6 = N.C intersection lever

1. At 0 degrees, disconnect the air supply to the machine.

2. Remove the cover from the nozzle change drive gears.

3. Turn the 14

station nozzle changer solenoid OFF at 0 degrees. (Y036)

4. Move shaft A to the 15

station and install the alignment jig.

5. Carefully rotate the jig into the 14

station and set the cam at 200 degrees.

Caution: because the jig spans two shafts, never rotate the cam outside of stations 14 and 15.

6. Confirm that the N.C axis fits smoothly into the jig. If not, adjust by loosening the up/down and

forward/backward positioning bolts and utilizing the adjustment bolts.

7. Confirm that the N.C intersection lever shown in figure 15 (item 6) is horizontal when the cam is at

0 degrees. Adjust otherwise.

4.9.2 Nozzle Changer Gear Backlash Adjustment

1. Confirm that the two gears where the motor intersects the NC axis are aligned correctly. Then,

lock the 4 small set screws (there are two on each gear):

One of 2 set screws on each

bevel gear. (Ensure the

screws are seated at the

flats on each shaft.

)

Figure 17

2. Turn the servo ON.

3. Place a dial gauge on the lower of the two gears (figure 18) and measure the backlash of the gear

at four points: 0, 90, 180 and 270 degrees. The backlash should be in the range 0.03 to 0.13mm.

If the backlash is not in range, realign the two gears as described in step 1.

4.9.3 Nozzle Changer Stroke Adjustment

1. Turn the servo OFF and attach a nozzle holder to shaft A.

2. Set the 10

station RQ to its original position and rotate the A-shaft through the 10

station to

make sure the nozzle holder is aligned correctly.

3. Rotate the “A “ shaft with holder attached to the 13

station at 0 degrees.

4. Turn ON the 14

station, nozzle changer solenoid valve by I/O: [I/O] → [Standard] →

[OUT] → Y037 ST14 NOZ CHANGE SOLENOID ENGAGED.

5. Rotate the A-shaft towards the 14

station and just before the nozzle changer clutch engages with

the nozzle holder (at around 130 degrees) place a dial gauge on the nozzle holder as shown in

figure 19 on the following page.
