Items to be set Set value
Explanation
Comp. Tolerance
Specifies the tolerance of the shape
as a percentage.
Search Area (mm) Sets the range of the detection.
Body Size X (mm) Sets the size of the outer edge.
Body Size Y (mm) Sets the size of the outer edge.
Body Size Z (mm) Sets the size of the outer edge.
Cntr. Offset X (mm)
Sets the offset amount in the X
direction from the center position.
Cntr. Offset Y (mm)
Sets the offset amount in the Y
direction from the center position.
Cntr. Offset R (mm)
Sets the offset amount of the angle of
rotation.

Designates the detection direction
0: Auto, 1: left side/upper side only,
2: right side/lower side only, 3: both
sides
(With Auto detection, the direction in
which the component extends beyond
the search frame is not detected.)

Specifies the priority to perform “Cut

Table 92
Note:
The parameters other than those shown in
Table 92
are not used, and should be set to 0.
Note:
*1. This option parameter consists of one byte of data, and each bit has different meaning.
(Please refer to P.142, Note*3 for the details.)
*2. Set the Offset 1 in
Figure 109.
*3. Set the Offset 2 in
Figure 109.

Note:
*4. It is possible to specify execution of the position detection on the detection lines from L5
through L8 by using the value in the field of Vision Option 1. If the value is set to 0,
position detection is normally performed in both the left and right (or upper and lower)
directions, but if the contour extends beyond the search frame for the detection direction

of the component, detection is not performed in that direction. In the example in Figure
110, as the search range does not encompass the right side of the component,
recognition is performed only on the left side. In this case, the search range serves as the
reference for the offset on the right side. Also, the center position of P7 and P8 that have
been determined at this point are averaged, and the result is offset by the amount of the
component size to determine the component center.
If the value is set to 1, detection is performed only on the left (upper) side, regardless of
whether the contour is entirely within the search range or not. (This is the same as the
example in Figure 110, except for the point that the component extends beyond the
search range.)
Figure 110
Note:
*4. If the value is set to 2, detection is performed only on the right (lower) side, regardless of
whether the contour is entirely within the search range or not. In this case as well, the
center position of the obtained edge positions are averaged, and the result is offset by
the amount of the component size to determine the component center. For instance, in
the example in
Figure 111
, P5 and P6 positions that have been determined are averaged,
and the resulting position is offset by the component size and determined to be the
component center. It is also possible to perform recognition on the components vertically
placed. In this case, the direction would be set to N-S, not to E-W.
