[10-2] STU Loading
1) Cut the power to the machine.
2) After checking the STU type and module specified for loading in the specification manual, set the
STU in the MFU (D9). Also connect the STU coupler connector part request cable to the device
number 9 connector and the tray out cable to device number 8.
3) Load the MFU in the machine being careful of the cables. After the MFU is loaded, connect the
STU power cable and air tubing.
4) Once the cables are connected turn the power to the machine on and verify that the [POWER ON]
lamp on the rear of the STU is lit

Proper Data Check
After checking the following Proper data items transmit the Proper data to the machine and
then reboot the machine.
Module Proper data
* PLM? Device Type
0: Recognize IP type feeders
* PLM? STU_Type
0: Compatible with a Y-direction length of up to 250 mm (STU2)
1: Compatible with a Y-direction length of up to 330 mm (STU1)
* PLM? IPDO_X, Y, Z
Go to section [6-24& 25] and enter the measured values.
When entering the Proper data items above, if Package_Type in the Package_Edit data of the
placement part is set to “0”, the machine will recognize parts supplied from an STU.
[10-4]
 
Tray Positioning Side Plate Parallel Measurement
1) Set a dial gauge on the placement head, move in the Y-direction and measure the side steel plate.
Tolerance: Within 0.5 mm
2) Set the dial gauge in the same way, move in the X-direction and measure the front steel plate.
Tolerance: Within 0.3 mm
[10-5] Tray Position Check Sensor & Add Check Sensor Adjustment
1) After connecting the STU cable and air tubing, the STU power will come on when the machine
power is booted up.
2) Adjust the tray position check sensor and add check sensor light beams so they are aligned at the
provisional heights by loosening the sensor mount hollow bolts and moving the sensors up and
down. Check the servo amps while doing this. Temporarily adjust the sensors so that the height
of the add check sensor is higher than the tray position check sensor.
3) Load a standard 100-pin size empty tray (used when acquiring data) on the STU tray holder and
then load the device jig used for Proper data measurement next to the STU at device position
number 11.
4) When the I/O Y02D SEND PART D9 of the loaded module is turned on, the tray holder rises, the
top of the empty tray set in the previous step is detected by the tray position check sensor and the
holder then stops.

5) Move the sensor up and down to adjust it so that the height at which the holder stops is the same
height as the Proper data IPD0_Z height measured in section 7.22. Use the adjacent jig and a
scale to check the height as it is adjusted.
6) After the height of the tray position check sensor is adjusted, load a 2 mm thick board on the top
of the empty tray. Adjust the sensor height so that this board is detected by the add check sensor
but so that the Fuji standard 1.6 mm thick board is not detected.
 
[10-6] Tray Existence Check Sensor Adjustment
1) Lower the empty tray that was loaded in the previous section and then load a 2 mm thick board
on the tray holder.
2) Loosen the tray check sensor dog attached to the bottom of the STU and then move the dog to a
position where the sensor will not come on even if raised when there is no tray.
3) Turn the I/O Y02D SEND PART D9 on and raise until the top of the 2 mm board is detected by
the tray position check sensor.
4) At the position where the top of the board is detected, use the dog that was loosened earlier to
adjust the tray check sensor so that it comes on at the same time.
5) After adjustment is completed, remove the board, set the I/O SEND PART D9 on with no tray on
the holder and then raise the holder.
- After the tray holder rises to the tray position check sensor, if the sensor determines that no tray
exists and then descends this completes adjustment of the sensor.
- If the tray holder does not descend but stops at the tray position check sensor position then the
tray check sensor must be adjusted again.

Tray Holder Lower Limit Sensor Adjustment
The tray holder position at which adjustment in the previous section finished should be the lower
limit. Mark the position of the top of the tray holder. Then go to the I/O and just as was done in the
previous section raise the holder with no board loaded. Verify that the distance from the marked
position to the top of the tray holder when it stops at the tray position check sensor is greater than
the maximum tray stacking height of 50 mm.
If the distance is less than 50 mm then lower the mounting bracket to adjust the distance to more
than 50 mm.
[10-8]
 
Tray Holder Parallel Measurement
Use a dial gauge to measure the parallelism of the top of the tray holder at the upper limit and lower
limit.
[10-9]
 
Tray Remover Forward and Retract Limit Adjustment
When at both the forward limit and retract limit mechanical stopper positions, loosen the dog and
move it until the sensor goes off. Then move the dog back to find the position at which the sensor
comes on. From this position move the dog back another 1 mm and secure it in place.
