6 Decide on the pattern size.
Following the message “Please teach template size and position. (Step 1)”
displayed on the operation monitor, enclose the pattern with a square
window by using the [TAB] key and arrow keys. Adjust and determine the
window size and position as explained below, then press the [ENTER] key.
The area enclosed with the window is registered as a template.
[TAB] key
Each time you press the [TAB] key, the start point (stationary point) of
the window changes to “lower right corner” → “upper left corner” →
“center”. Select the starting point with which you can enclose the
pattern easily.
Lower right corner start (stationary) point:
The window can be enlarged or reduced with the arrow keys, using
the lower right corner of the window as a start point. However, the
window cannot be expanded further right or downwards of the start
point.

key while holding down the [SHIFT] key, the entire window moves to
larger distance.

7 Teach the center of the pattern.
1. Following the message “Please teach the template center. (Step 2)”,
align the center of the window (template) with the center of the pattern
and then press the [ENTER] key. If they are already aligned, just press
the [ENTER] key.
2. The message “Do you want to save this template?” then appears. Press
the [ENTER] again to save the pattern. If you do not want to save it,
press the [ESC] key.
Reference
If the pattern size is too large, a “template size error” may occur. In this case, redo the
procedure from Step 6.
8 Check the image.
Execute the DISP. PATTERN command when registration is complete. The
image of the pattern enclosed by the window is displayed on the upper left
of the vision monitor. If an acceptable image cannot be obtained, redo the
procedure from Step 6.
