Rotation Correction
Use the rotation correction to distinguish the shape of a work by correcting
its rotating angle even if a work rotates during detection.
■Registration of the Color and Pattern for the Rotation Correction
In order to execute the rotation correction, you must register a color
different from the color for the position & magnification correction.
Register the color and pattern for the rotation correction from the teaching
menu in the following procedures.
Here explained is the method to register the quadrangle at the lower right
in the screen as the color and pattern for the rotation correction.
Always register a color of the same size out of the colors not
included in the background for the rotation correction just as
done with the color for the position & magnification correction.
Registering a color other than white, gray, and black, will
make the recognition more stable even when the brightness
changes. Stabilize even when brightness changes.
However, select a color at a position apart as much as
possible since the error at the rotation correction is greater
when the color for the position & magnification correction is
close to the center position.

Before registering the color for the
rotation correction, register the
color and pattern for the position &
magnification correction, referring
to "Position & Magnification
Correction". (
