7.5.3.5 Option “Test fiducial”
NOTE
The option “Test fiducial” is only activated if
— you have already entered a fiducial number and
— a definition already exists for the number selected.
Fig. 7.5.10
The dimensions of the pattern structure and search area are stored in the station computer. These variables
are required for the calculation of the traverse paths for the corner test. The centering offsets of a centering
operation which may have been carried out previously is also taken into account in the calculation of the
traverse paths. After this
–
the test sequence is displayed via the video image,
–
the header line is displayed with the option, the fiducial number and the quality factor.
–
in the footer line the control panels and command sequences are displayed and a test procedure initiated
which determines the quality factor of the fiducial.
●
By pressing the “RETURN” key you can repeat the test procedure.
●
With the arrow keys you can change the gantry position. By entering the numbers 1 ... 6 you can change
the increment.

The PCB camera travels to the 4 corners of the search area and executes in each case a measurement com-
mand. For each executed measurement command the machine controller receives the fiducial quality from the
vision evaluation unit (MVS). The worst value (worst case) of the tests is shown on the monitor in the header
line. The quality level ranges from
–
0 = bad to
–
100 = very good
and should not fall below value of 40 for the fiducial and the ink dot. Otherwise we recommend you select
another fiducial.
NOTE
Here compare also the relationship between uniqueness and fiducial quality as described in Section 7.5.3.2
Option “New fiducial”.

7.5.3.6 Option “Move x / y axes”
When you select this option in the menu “Teach fiducial”, the station computer initiates the following actions:
–
The screen switches off the menu “Teach fiducial” and displays the video image. Here the current camera
position is displayed and the control panel option shown.
–
If there is a risk of crashing, the axis controllers are blocked.

●
After having selected the increment, selectable using the numbers 1 to 6, you can vary the camera position
of the gantry 2 using the arrow keys.
NOTE
Gantry 2 is always used as the default teach gantry. Gantry 1 can be selected using the Option “Choose
gantry” (see Section 7.5.3.9).
●
With “ESC” you can quit the option. The menu “Teach fiducial” is displayed once more.
