6.6.3 Setting Procedure
1. Set a checker area following "Basic Settings of Checker". (See page 66.)
Notes on area shapes
Shape Description
Line Scan
Detects edges using a line. This feature allows the
AX40 to detect the edges faster than plane scan.
Use the Line Scan function mainly for detecting a
horizontal plane edge. Note that if there is a
foreign object in the lines, the device may detect
the object.
Plane Scan
Detects edges in the multiple lines by setting the areas of rectangles. The detecting
time of an edge is longer than that of Line Scan. If a foreign object is detected in the
rectangle areas, the AX40 will ignore the object and detect the edges stably. Use the
"Plane Scan" function especially for detecting the tips of a circle or a sharp image.
2. Select "Direction" to press the ENTER key.
Select "Horizontal "/ "Vertical" from the submenu.
"Horizontal"
Scans from the start point toward the end point
scanning
in horizontal direction. (Horizontal direction
scans on the monitor screen)
"Vertical"
Scans from the start point toward the end point
scanning
in the vertical direction to detect an edge
(vertical direction scans on the monitor screen)
