WinMark Pro tracking setup
Figure 5 -23 illustrates Sensor Distance when the part sensor is positioned downstream. Even though
the leading edge of the part has traveled past the center of the mark field, the area where the part is to
be marked must still be upstream of the centerline.

Maximum tracking speeds are obtained when mark objects are positioned near the upstream edge of
WinMark Pro’s Drawing Canvas and the Motion Vector is set to 90° or 270°, which takes advantage of
Flyer’s rectangular marking field.
When positioning objects on the Drawing Canvas, remember that each marking object has an Object
Reference Point, which is the object’s top left corner (in the direction of part motion). The specified Sen-
sor Distance must be greater than or equal to the absolute value of the X-position or Y-position reference
point coordinate. When the tracking Motion Vector is 90° or 270°, Sensor Distance must be greater than
or equal to the absolute value of the Y-position Object Reference Point. When the Motion Vector is 0° or
180°, Sensor Distance must be greater than or equal to the absolute value of the X-position coordinate.
If Sensor Distance minus the X- or Y-position Object Reference Point is less than zero, this means that the
desired mark location is past the position of the Mark on the Drawing Canvas at the moment of part sense.
To correct this “Invalid Sensor Distance” error, move the physical part sensor further upstream to increase
Sensor Distance. If line speed (cycle time) is not an issue, you can instead move the object’s location on
the Drawing Canvas. In Figure 5 -24, the text object’s top left coordinate value is X = –0.5, Y = 2.0 (inch-
es). If the Motion Vector is 270°, then Sensor Distance must be 2.0 inches or greater.
