6.2 NZ-Axis Adjustments

Procedure:

1. Loosen the NZ-axis motor coupling and push it against the minus

mechanical stopper.

2. Manually rotate the motor until the counter value reads zero, then

tighten the coupling (torque: 0.8 Nm).

3. Pull the axis against the minus mechanical stopper and ensure the motor

position is 0 ± 50 pulses. Move the axis 100 pulses away from the

stopper position and set this in calibration data using the following

commands:

[MAINTENANCE] → [CALIBRATION] → [TRAVEL LIMITS] →

[MINIMUM LIMIT NZ].

4. Pus the axis against the plus mechanical stopper and ensure that the

motor position is 12770 ± 500. Move 100 pulses back from this position

and set this in calibration data using the following commands:

[MAINTENANCE] → [CALIBRATION] → [TRAVEL LIMITS] →

[MAXIMUM LIMIT NZ].

5. Rotate the cam angle to zero and activate the pickup solenoid using the

I/O: Y031 ST1 PICKUP SOL ENGAGED.

6. Set the pickup height jig to zero, and remove the stopper bracket. Then

slot the jig onto the device table (slot no. 23) and install the nozzle jig on

the nozzle holder (no. 1).

7. Rotate the cam axis to 170°, ensuring that the needle of the pickup height

jig is directly below the nozzle jig.

8. Manually move the NZ-axis until the dial gauge reads zero (at this point

there should be a space of 0.65 mm between the tip of the nozzle and the

feeder). Take note of the motor pulse count at this point.

9. Repeat the procedure for all 16 heads. Take the average value of the 16

heads and set this as the NZ origin position in the machine’s calibration

data using the following commands:

[MAINTENANCE] → [CALIBRATION] → [PICKUP REFERENCE] →

[NZ ORIGIN POSITION].

Ensure that new Calibration data is backed-up to the host computer

once the adjustment procedure is complete.
