target color is displayed. If not, increase the set value of COLOR% P
or COLOR% R (Color margin) or adjust TEMPCOMP (Temperature
compensation level).
The center of the color for the position correction may be close to
the center of the color for the rotation correction.
• The error will be greater when their positions are close. Select a color
at the farthest position.
A part of the color for the position correction may be outside the
imaging area.
• If it is, the number of the pixels for the color varies. In such a case,
specify other color and do not make the position correction.
Rotation correction shifts.
The color also existing at the side may be selected.
• The center coordinates of the color change by the rotation angle. Select
a color in the rotation surface.
Position correction, Magnification correction, or Rotation
correction is not done.
The set value of MAGNIFY% (Magnification correction allowable
ratio), POSIT%X (Horizontal position correction allowable ratio),
POSIT%Y (Vertical position correction tolerance), and ROTATE%
(Rotation correction tolerance) may be small.
• If the set value is small, the correction area is limited. Increase the set
value and confirm the correction result again.
Position & magnification correction or rotation correction
is done.
Cancel the registered color for the correction.
• So as not to make any correction, set the color display at the right of
STD TEACH and ROTATION on the teaching menu to [XX].Select
an intended item to display it in yellow, and then press
