Min/Max Parameters - Glossary:
In order to understand the purpose and function of the Min/Max width parameters, it is necessary
to define the various parts of standard Line and Edge patterns:
Line Patterns
Line patterns are defined by three regions. The
Left
region is the area located to the left of the
registration line, the
Center
region is the registration line itself, and the
Right
region is the area
located to the right of the registration line. By defining the size of these regions using the Min/Max
Left, Min/Max Center, and Min/Max Right parameters, the sensor can be configured to track the
center of the registration line and ignore any other printing within its field of view.
Edge Patterns
Edge patterns are defined by two regions. The
Left
region is the area located to the left of the
edge to be tracked, and the
Right
region is the area located to the right of edge to be tracked.
[ Note: Edge patterns do not have a
Center
region.] By defining the size of these regions using
the Min/Max Left and Min/Max Right parameters, the sensor can be configured to track the edge
of the registration stripe and ignore any other printing within its field of view.
