[4-9] Proper Data Zero Offset Q-Measurement
1) Verify that the "Center_Offset_X,Y", "Final_Offset_X,Y,Q", and "Zero_Offset_Q" Proper data
items are set to "0" at all modules. At systems with MTUs, also verify that
"Zero_Offset_TY,TZ" is set to "0".
2) Following the Q-axis zero setting adjustment, perform another Q-axis zero setting.
3) Following the zero setting operation, lower the Z-axis to a position where interference will not
occur when the jig (described at the following step) is mounted.
4) Mount a Q-axis zero measurement jig at the holder mounting position (bottom of gear). The
jig's mounting orientation is indicated on the top face of the jig. The jig can only be mounted
on the gear when oriented in this direction.
5) Turn the Q-axis in the zero setting direction until the jig's measuring face is parallel to the
X-axis.
6) Set a dial gauge against the jig's measuring face and turn the Q-axis until a reading of "0" is
obtained at both ends.
7) The servo counter reading at the point where the dial gauge reading is "0" is the Q-axis zero
offset.
8) Enter the PLM1 to PLM6 "Zero Offset Q" values to the F4G, then transmit this data to the
machine.

Axis Zero Setting Adjustments in the Mechanical Check Mode
[4-11]
 
Before Beginning the Axis Zero Setting Adjustments
1) Start up the machine in the "Mechanical Check" mode.
2) If the coupling and belt are removed with the 200V power on,
the motor will vibrate. To prevent this, press the Emergency
Stop button (200V off), then connect a digital operator to
ch3 of each axis amplifier and lower the CN-04 gain to " 80" .

X-Axis Zero Setting Adjustment and Belt Tension Adjustment
1) Remove the X-axis timing belt.
2) Use the following command sequence to select module 1: [MODULE FIX]è[Number of
module to be adjusted (Ex.)]è [CR]. Next, execute a return using the [RETURN] command.
Continue by selecting the X-axis as follows: [MOVE]è[ZERO SETUP]è[NEXT AXIS].
Press [START] to begin the zero setting operation.
3) Block the X-axis deceleration sensor beam and end the zero setting operation.
4) Execute the [RETURN] è [STROKE] è [NEXT AXIS] commands to select the X-axis, then
move (by inching) the X-axis to the 4000 pulse position (-4000 at rear part-supply machines)
while watching the displayed counter reading.
5) 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 4000 ± 200 pulses (-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
6) 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).
7) After the adjustment, connect a digital operator to CN-04 again and return the gain to "500"
from "80".
[4-13] Y-Axis Zero Setting Adjustment
1) Perform the Y-axis zero setting adjustment in the same manner as that described for the X-
axis, adjusting until the values shown in section [4- 6] are obtained.
2) After the adjustment, connect a digital operator to CN-04 again and return the gain to "500"
from "80".
[4-14] Z-Axis Zero Setting Adjustment and Belt Tension Adjustment
1) Perform the Z-axis zero setting adjustment in the same manner as that described for the X-
axis, adjusting until the values shown in section [4- 7] are obtained.
2) After the adjustment, connect a digital operator to CN-04 again and return the gain to "450"
from "80".
[4-15 ] Q-Axis Zero Setting Adjustment
1) Perform the Q-axis zero setting adjustment in the same manner as that described for the X-
axis, adjusting until the values shown in section [4 - 8] are obtained.
2) After the adjustment, connect a digital operator to CN-04 again and return the gain to "300"
from "80".

[Chapter 5] Before Beginning the Proper Data
Measurements
[5-1] Attaching the Nozzle Changer Holder Bracket and Q-Cover (For Index Types Only)
1) End the Z-axis zero setting operation and lock the servo.
2) Mount the holder bracket at the head from which it was removed (see section [5-4]), partially
tightening it there with the M5 x 10 bolts and disc springs.
3) Use the M3 x 5 bolts and spring washers to mount the Q-cover for the index nozzle at the bottom of
the placing head.
[5-2] Mounting the Index Holder and Adjusting the Holder Bracket
1) Mount Index type holders on the gear in the same manner as the Q-axis zero measurement jig,
using the M5 x 15mm machine screws and spring washers. When mounting the holder, note the
positioning pin on the top face. A stepped collar (28mm thick) is installed between the holder and
the gear.
2) With the holder shaft against the bracket, turn the holder to the shaft's most contracted position.
At this position, set a dial gauge in the Y-direction and adjust until the holder's inner gap is
within a "0 to 0.05mm" range, with the holder shaft ends making contact with the bracket's
left and right sides in an even manner.
