Perform the vision test.
Press the [Test] button and check to see if the pattern is correctly recognized. Repeat this test several
times. When no error occurs, the pattern data is appropriate.
If an error occurs, check whether "Search Area" of the Vision parameters is appropriate. If the search
area is too large so that other marks are located within the search area, then reduce the search area.
Conversely, if the search area is too small, then enlarge the search area.

Pattern matching can be used in the same way as the fiducial marks. In this case, enter the mark No. registered

"Mark 1" and Mark 2" columns.
