[Chapter 4] Axis Zero Setting Adjustment

[Explanation of Chapter 4]

This chapter describes the axis zero setting adjustment procedure which is performed at the

standard display screen. Be sure to verify that zero settings have been specified before

attempting this adjustment procedure. The "mechanical check" mode zero setting

adjustment procedure is described at the end of this chapter. Select the procedure which is

appropriate.

X axis 0.0025mm / Pls

Y axis 0.0025mm / Pls

Z axis 0.0015mm / Pls

Q axis 0.005degrees / Pls

[4-1] Cooling Fan Operation Check

Verify that all cooling fans are operating when the PLM starts up at power on.

[4-2] Digital Amplifier Parameter Check

Connect a digital operator to "ch3" of the amplifier being checked,

and verify that all settings are correct.

[Using the digital operator]

1) Connect the digital operator to each servo amplifier.

Either "[-.bb]" (100V) or "[run]" (200V) displays at this time.

2) Execute the following sequence to verify that the "CN-00" parameter is "00-00":

[–.bb [–.bb] à DSPL à Cn-00 à DATA

SET ENTER

3) Execute the following sequence to verify the "CN-01" parameter:

DSPL à Cn-00 à à Cn-01à DATA

SET ENTER

* Reverse the above sequence to return to the original display.

[4-3] Temporary Zero Setting

Adjust until a zero setting is possible.

Press the [START] button to end the zero setting procedure.

Note: If the zero setting cannot be ended, adjust each axis using the mechanical check mode

zero setting procedure described in section [4-2].

[4-4] Before Beginning the Axis Zero Setting Adjustments

1) If an index holder or a single nozzle holder is mounted at the head, be sure to remove the

holder to prevent interference with the table and brackets.

2) If an index head is being used, remove the nozzle changer holder's bracket. Do not remount

this bracket until just before the Proper data measurement is performed.

3) Press the Emergency Stop button to turn off the 200V power supply.

4) Execute the following on-screen command sequence to display the servo counter screen for

the module to be adjusted: [SET]->[SERVO]->[Number of module to be adjusted]->[CR]

5) Remove the X-axis timing belt, the Y-axis coupling, and the Z-axis timing belt, then adjust

each axis as described in the following sections.

[4-5] X-Axis Zero Setting Adjustment and Belt Tension Adjustment (Same Procedure for all Module Types)

1) While watching the displayed counter value, turn the X-axis motor by hand to the 4000 pulse

position (-4000 pulse position at rear part-supply machines).

2) Move the head to the mechanical stopper at the machine's right side (as viewed from the part

supply side), then attach the timing belt and adjust its tension.

Belt tension tolerance:

227HZ±10HZ

After adjusting the belt tension, move the head back to right-side mechanical stopper position

and verify that the counter reading is within 40 00±200pulses (-4000 pulse position at rear

part-supply machines).

* Flip chip modules have a coupling drive system rather than a belt drive. At these modules,

adjust the X-axis to a 4000±100 pulse position .

3) After completing the above adjustment, adjust the X-axis deceleration sensor position so that

the sensor switches on at the -5500 pulse position. Following this adjustment, use the

"CHECK, X006, X AXIS ZERO" I/O to verify that the sensor switches on at the -5500±100

pulse position (5500 pulse position at rear part-supply machines).

[4-6] Y-axis Zero Setting Adjustment

1) Adjust in the same manner as for the X-axis (see above), so that the distance from the zero

setting completion position to the mechanical stopper is 4000 ± 100 pulses (-4000 at rear

part-supply machines), and so that the deceleration sensor switches on at the

-6000 ± 100 pulse position (6000 at rear part-supply machines).

2) Verify that the coupling slides smoothly (is centered) between the ballscrew and the motor

shaft. Install the coupling so that its center is aligned with the center between axes (the

best way to do this is to secure the coupling with it pressed against the end of the ballscrew).

Be sure that there is no tensile or compressive stress acting on the coupling.

3) Use a torque wrench to tighten the coupling.

Y-axis coupling tightening torque: 34.0 kg.cm

[4-7] Z-Axis Zero Setting Adjustment and Belt Tension Adjustment (for all Module Types)

It change the way of the adjustment for Z-axis Zero setting, because it occurs a problem that a

nozzle interferes with the lighting when Zero setting on the lighting unit for Camera type 7.

[New adjustment]

1) Remove the Single holder and the Index holder.

2) Zero setting for Z-axis. (Set “PLM* Zero Offset Z” in Proper Data to 0.)

3) Put the measured jig for Mark Camera resolution (AJPJ0062) on the conveyor, and clamp it.

4) Put the following jig for each holder type on the jig, AJPJ0062.

Index Holder Z9417BHPJ0040 (It is put a carved seal “I” on the body)

Single Holder (stroke=2mm) Z9417BHPJ0050 (It is put a carved seal “S-2” on the body)

Single Holder (stroke=3.5mm)Z9417BHPJ0060 (It is put a carved seal “S3.5” on the body)

5) Turn the servo OFF.

6) Lower Z-axis manually until the holder installing face of the head touches on top of the jig.

7) Adjust the dog so that the reduced sensor turns ON at this position. (The difference between

the position of touching to jig and the position of reduced sensor ON is +/-20 pulse.)

8) Calculate the counter from the position of reduced sensor to upper mechanical end by

moving the Z-axis.

9) Remove the timing belt, and set the counter of the motor to the value which minus 5000

pulse from calibrated value on (8).

10) Raise the Z-axis to the upward end to install the timing belt.

When installing the timing belt, adjust the belt tension at the same time.

Tolerance for belt tension : 434HZ +/- 10HZ

11) Down the Z-axis, and verify that the position of the reduce sensor ON is within –5000 +/-

170 pulse

12) Set the "PLM* Escape Position Z" in Proper data to "2000".

Secure the coupling so that its center is aligned with the

center between axes. (the best way to do this is to secure

the coupling with it pressed against the end of the

ballscrew). Be sure that there is no tensile or compressive

stress acting on the coupling.
