properly.

*1: If started up correctly and the 200 V power is on this should be in the "O" status but if
the 200 V power is cut this will remain in the "X" status even after the 200 V power is
rebooted. In this case operate the TY-axis and TZ-axis individually and then check.
[8-8] Proper Data Transmission
1) After confirming that all of the cables are properly connected to the machine, turn on the power to
the machine.
2) Enter the following Proper data items and then transmit the Proper data to the machine.
Device Type = 2
Zero offset TY, TZ = 0
Original Position TY, TZ = 0
Max, Min Limit Position TY, TZ = enter the provisional values
(Measurement of Zero offset TY, TZ, Original Position TY, and TZ is finished but the values here
are merely for reference so enter as zero. Also enter the values that have already been measured for
Max, Min Limit Position TY and TZ as temporary values.
These Proper data items will be re-measured later.)
3) Once transmission of the Proper data has been completed be sure to cut the power to the machine
and reboot.

Zero Set Check
Remove the TZ-axis zero set sensor dog.
Once machine zero set has finished, MTU zero set begins. Trip the TY-axis negative side sensor (machine interior side)
prior to entering MTU zero set. If [START] is then pressed and zero set begins, the MTU will determine that the shuttle
is on the negative side thereby initiating TZ-axis zero set.
(If the TY negative side sensor is not tripped in time or if the positive side sensor is tripped, it is
determined that the shuttle is not in the retract position and the TY-axis moves first until it reaches the
negative side sensor before the TZ-axis moves. Once the TY-axis reaches the retract position, zero set of
the TZ-axis and TY-axis begins in that order.)
Use a scale to trip the TZ-axis zero set sensor and complete TZ-axis zero set. TY-axis zero set then
commences. Complete zero set of this axis in the same manner. Zero set is complete once both axes are
zero set. Maintain the 200 V power until adjustment is finished.
1) TZ-axis adjustment
Slowly raise the three TZ-axis ball screws and insert a 10 mm thick jig plate between
the stopper and each respective ball screw. Set the TZ-axis timing belt in this
position.
Note: There are three TZ-axis ball screws. Carefully attach the belt so that the height of
each of the ball screws is the same.
Belt tension: 46.90 Hz ± 10 Hz
Raise the axis 5 mm (+ 500 pulses, 15 mm from the mechanical stopper) from this
position and attach the dog that was removed previously. Adjust the dog up or
down so that the zero set sensor comes on.
2) TY-axis adjustment
Attach the timing belt with the shuttle in a position 3 mm (40 pulses) from the negative
side mechanical stopper.
Belt tension: 40.69 Hz ± 10 Hz
Move the sensor bracket to adjust the zero set sensor so that it comes on in a position
+ 65 pulses (105 pulses from the negative side mechanical stopper) from the position at
which the timing belt was installed.

[8-10] Shuttle Parallel Measurement
From the operation display screen carry out the following command operation to
move the shuttle to the advance limit; [POSITION], [MTU], [SHUTTLE],
[ADVANCE], and then press START. In this position measure the parallelism of
both ends of the shuttle jaw. If the difference between the ends is greater than 0.2
mm, use the mounting screw clearance holes to adjust.
[8-11] Shuttle Slope Levelness Measurement
Attach a dial gauge to the machine placing head and measure the levelness of the
plastic surface attached to the top surface of the shuttle surface. Adjust by inserting
shims so that the variation from (1) to (4) is within 0.1mm and such that the variation
from (5) to (8) is within 0 to -0.1 mm of the respective slopes.
[8-12] MTU Descent Speed Adjustment
Raise the MTU to the maximum stroke using the hydraulic jack and use the speed
controller on the side of the jack to adjust the time from the opening of the hydraulic
jack valve to the end of descent, to between 6 and 10 seconds.
