Positional
Information
When selecting a Video Model, if the image shapes have edges all in the X
direction or all in the Y direction, not enough positional information exists for the
camera system. An image with good X and Y information is necessary for
accurate positioning:
Preparing the
Vision System
The vision system learns the fiducial during a board setup. The fiducial
coordinates are entered into the product file during the editing of a default file.
Initially this enables the camera to find the fiducials. The setup needs to be run
in step mode from the status page.
The following procedure is typical for all fiducial shapes, although in this
instance a circle fiducial shape is referred to throughout.
1. Select Mode (F1) until Step is indicated in the mode option on the monitor.
2. Select Exit (F8).
3. Place the board onto the conveyor.

Video Model
The procedure for creating a Video Model is very similar to that for creating a
Fiducial, throughout the following fiducial procedure, boxes like this contain
alternative procedure steps, to allow the setup of a Video Model.

The board fiducial/select mark should now be visible on the vision data
window.
If selective print/pass through is enabled, the image on the left hand side of
the monitor is the board select mark. The right hand side of the monitor
shows the corresponding position on the stencil, which is a mirror image of
the board without the select mark. While the select mark is being setup and
the menu bar is as Step 8, the message ‘The form of this fiducial will
select Print / Pass through’. is displayed.
If the fiducial is in the field of view go to Step 10. If the fiducial is not in the
field of view, continue with Step 8.

For each press of Search Step the camera conducts an increasing spiral
search to enable the operator to locate the fiducial. If this search is not
