[SERVO_LIMIT] and set [T_MinusLimit] and [U_MinusLimit] to “0”.
9. Finally shutdown and then restart the machine.
9.8 Setting the plus limit
1. Remove the tray catch stopper from the U axis plus limit side.
2. Move the T and the U axes to their plus mechanical stoppers and select [Maintenance C]
– [Proper Data Editor] – [SERVO_LIMIT] – [T_PlusLimit] and [U_PlusLimit] – [Direct
Servo Input] to save the current counter value to proper data.
9.9 U-Axis belt slippage adjustment
1. Use a feeler gage and adjust the roller guide so that the distance between the roller and
the belt becomes 0.1mm.

2. Verify that the roller rotates with the belt when the belt is pulled manually.
3. Remove the jumper and replace the “35BKT1-CN2” cable in the side 1 electric box and
confirm the brake is on even when the servo power is OFF.
9.10 T-Tray origin (magazine adjustment and measurement)
1. Jog the T-axis until the right hand side of slot [41,42] is level with the U axis conveyor rail.
Use the dial gages and jig (Z9731ADEPJ8131):
2. With the T-axis in the same position measure the height difference between the left side
of slot [41, 42] and the U axis conveyor rail. The height of the magazine slot should be
0.03mm higher than that of the U axis conveyor rail. The reason for this is that the MTU
magazine is fixed at the right hand side (when viewed from the machine rear) but not at
the left-hand side. When trays and tray parts are loaded on the left-hand side it is
weighed down and lowers slightly in relation to the right hand side.
3. If necessary adjust the height of the left hand side of slot [41,42] using the bolt on top of
the magazine, see diagram below:
4. Jog the T axis so that slot [01,02] is roughly level with the U axis conveyor rail.
5. Use the dial gage and jig to find the position where the right hand side of slot [01,02] is
0.04mm above the U axis conveyor rail.

6. Select [Maintenance C] – [Proper Data Editor] – [TRAY] – [T_TrayOrg] – [Direct Servo
Input] to save the current T axis position as “T_TrayOrg” in proper data.
9.11 Guide rail adjustment
1. Place an empty tray pallet in slot [01,02] and bring it to the “T_TrayOrg” position.
2. Adjust the upper guide rails so that they are 9mm above the tray pallet surface.
3. Adjust the lower guide rails so that they are 19mm beneath the upper guide rails.
9.12 U axis clamper parallelism check and adjustment
1. Use an extension bar to attach a dial gage to the placing head and adjust the parallelism
of the U axis shuttle so that it is parallel to the X-axis. Tolerance is 0.03mm. Refer to the
diagram and photo below:
9.13 Shuttle rail position adjustment
1. Use a dial gage to measure the width of all the slots. Find the average slot to use as a
reference, refer to the photo below:

To adjust the parallelism loosen these
two bolts
Use a dial gage to measure the width
of all the slots, and use the slot with
an average width as the reference.
