6.9.6 Teaching Fiducials
Depending on the options you have selected for vision use, you may be prompted to teach the workpiece
and two vision targets.
If your programming options are set to have two global fiducials, then FmXP will prompt you to teach
two target points on the workpiece. Choose images that are identical from part to part and in the same
location. With the Vision System Teach Screen you can specify a search window size. This helps when
there are multiple identical images within the field of view. You then teach the actual fiducial image and
size using the on-screen controls. The slider bars for lighting control can be adjusted as necessary to
provide optimum lighting and contrast. A found score is available if there is any question about the
quality of the vision target.
Once the vision targets are defined, the program sequence is ready to be inserted.
