Compensating For Position Offset (Position Compensation Items) - Omron FQ2-S/CH Series User Manual

Compensating for Position Offset (Position Compensation Items)

Use position compensation items if the position or orientation of the measurement object is not consistent.
When you use a position compensation item, the offset between the reference position and the position of the
object is calculated and the position of the measurement region is corrected before measurements are
performed.
Applicable Position Compensation Items
There are three position compensation items as indicated below. These items vary by detection method.

Adjusting the Images That Were Taken
A search is made for a characteristic pattern to detect and correct the
position.
• Shape Sear III.pos.comp (Shape Search Position Compensation III)
• Shape Sear. pos. comp. (Shape Search Position Compensation)
• Search position comp. (Search Position Compensation)
The color distribution or density changes in the object are used to detect
and correct the position.
• Edge position comp. (Edge Position Compensation)
• 2Edge position comp. (Two-edge Position Compensation)
• 2Edge midpoint comp. (Two-edge Midpoint Compensation)
• Edge rot. pos. comp. (Edge Rotation Position Compensation)
Position is corrected based on entered value and image.
