Purpose
Example
Measure the position coordinates of a workpiece with the same extracted color as
the reference color.
Application Positioning workpieces or parts. Positional deviation inspection.
* Even if the workpiece which has
had the color extracted moves its
position, the controller can
measure the positional coordinate
of this workpiece.
