1.2.4. Common XY Calibration
A process to coincide the coordinates of two Gantries. If it is not done correctly,
there will be an offset between Gantry 1 and Gantry2, which will not only affect
placement precision but also cause collision of gantries.
Figure 1-2.”Gantry-to-Gantry Common XY’ dialogbox
<Automatic Next> checkbox
Select this check box and click the <Next> button. Then the process that
matches the coordinate systems between gantries is performed automatically.
<Manual> checkbox
Move the gantry to the designated position by using the teaching box and
perform the process that matches the coordinate systems between gantries
manually.
<Test only> check box
When calibration is done after selecting this, the result is displayed but not
saved. Consequently, it is possible to check the changes made in the current
machine compare to the previous data.
<Device> combo box
Select the Fiducial camera to be moved.
<Move> button
Move the fiducial camera of the selected gantry.
Warning
Operation error caused by unauthorized or untrained
personnel or insufficient checking before calibration could
severely damage the machine
or the set up data, or it could cause personal injury of the
operator or the worker near the machine.
Before carrying out calibration, check the item to be
calibrated and check if there is any worker near the
machine.
And calibration must be carried out by an authorized and
trained user only.

Inner
Adjusts the inner lighting for the Down Camera of the selected Gantry.
Outer
Adjusts the outer lighting for the Down Camera of the selected Gantry.
1.2.4.1. Procedure
1. Click the <Move> button to move the fiducial camera to the designated
position.
2. Adjust the position of the fiducial camera by using the teaching box so that the
center of the cross hair displayed in the SMVision window matches with the
center of the fiducial mark that was already set on the conveyor. At this time,
all gantry cameras have to be movable to this position.
3. Click the <Get> button to reflect the current coordinate.
4. If the <Next> button is clicked after selecting the <Automatic Next> check box,
the same movement is performed automatically.
5. If finished properly, click the <Update> button.
The manual setup method is as follows.
1. Move the fiducial camera of the corresponding gantry to the position of the
fiducial mark selected from the Grid group.
2. Adjust the position of the fiducial camera by using the teaching box so that the
center of the cross hair displayed in the SMVision window matches with the
center of the fiducial mark that was already set on the conveyor
3. Click <Get> button to reflect the current coordinate.
4. move the other gantries to the position designated in step 1.
5. Click <Get> button to reflect the current coordinate.
6. Wait until the Gantry moves to Home, automatically detects Collision sensor,
and returns to Home again.
Caution
Be sure to perform the “Gantry to Gantry Common XY”
calibration before performing the ‘Gantry Mapping’
(Disable Condition). If ‘Gantry Mapping’ is already
enabled, perform the ‘Gantry to Gantry Common XY”
calibration after disabling the ‘Gantry Mapping’.
1.2.5. Conveyor Calibration
Calibration is made upon initial installation of the machine. The recalibration of
transport rail should be performed when mechanical adjustments to the transport
rail occur.

<Station> combo box
Select the Station.
<Positon> Group
Input the position of the fiducial mark of the selected station. First click the
<Home All> button to enable this edit box and find the home position for all
axes related to the conveyor.
Ref #1: the first fiducial mark of the selected station

<Home> Group
<Home All> button: Finds the homes of all axes.
<Home Shuttle> button: Makes the shuttle return to origin when the
shuttle is at the selected station. (F1, F3)
<Home Rail> button: Makes the Conveyor rail of the selected station
return to origin.
<Teach> Group
<Move> button
Move the fiducial camera of the corresponding gantry to the position of the
fiducial mark selected from the Grid group.
<Get> button
Apply the coordinate value of the current position as the selected fiducial
mark position.
