Perform Zero Set Again
After the Proper data items Zero_Offset_TZ and TY are input perform zero set again.
Note: Normally after zero set is completed the TZ and TY axes move by the amount of
Zero_Offset. Once this movement is finished, reset the servo count value of that position to
zero. If the Proper data is not input and zero set is not carried out again, the TZ and TY
axes Proper data items that are measured next will change.
Always input the Proper data and carry out zero set again before proceeding.

Max,Min Limit Position
Select [PROPER], [Max/Min], and [TY] [TZ] and then carry out [Max Limit] and
[Min Limit] measurement of each axis. For the shuttle, the camera side mechanical stopper
position is the [Min Limit] and the MTU side mechanical stopper position is the [Max Limit].
For the MTU the bottom mechanical stopper position is the [Min Limit] and the top
mechanical stopper position is the[Max Limit]. In the position where the axis is pressed up
against the stopper, press [SET] and the counter value will be automatically entered.

[8-20 ] Shuttle Jaw Adjustment
The following two figures show the shuttle at the retract limit as viewed from the top and the
side respectively. Use these figures as a reference.
 1) Original_Position_TY measurement & shuttle tray holder clamper adjustment
a) Zero set the machine.
b) Remove the cam follower bracket. Move the stopper bolt to a position where the end of the
bolt will not hit the shuttle plate even if the shuttle moves to the retract limit. (If it is
screwed in as far as possible there will be no interference.)
c) With the shuttle at the advance limit or any position other than the retract limit (some
intermediate position is okay), change the set position to adjust the retract limit cushion
dimension A so that it is 13 mm as shown in the figure.

d) Likewise, with the shuttle at the advance limit or some position other than the retract
limit and the tray holder in the set status, adjust shaft clamper dimension B so that it is
18 mm as shown in the figure.
e) Move the shuttle to the advance limit using the following command operation;
[POSITION], [MTU], [SHUTTLE], [ADVANCE] and press START.
f) Set the tray holder and then retract the shuttle via inching.
g) As shown in the figure, from the position where the front of the MTU tray holder stopper
and the rear of the tray holder are on the same plane, retract the shuttle a further 2.2 to
2.3 mm (about 27 pulses) and record the servo count value of that position.
h) Install the cam follower bracket as shown in figure B. (Secure in place temporarily)
i) Adjust the cam follower position using the cam follower bracket such that side C of the
cam and the shuttle plate are approximately parallel and so that there is a gap of about 4
mm between the tray holder and the shaft clamper as shown in figure A.
