Set the search conditions.
The Controller searches using a model that rotates in skipping angle (*2)
increments within the rotation range (*1).
The settings are used for all measurement regions.

Accuracy
Select the range for
model rotation.
Select the skipping
angle for the model.
The smaller the
angle, the more pre-
cise the search. Pro-
cessing time,
however, will be
longer.
Finds the measurement value in decimal point units. However, the processing
time is longer.
Position X and position Y: Subpixel units
•
Angle: 0.01 units.
Finds the measurement value in integers.
Position X and position Y: Pixel units
•
Angle: 1 units.
Coordinates and Rotation Angle Direction
Depending on whether a right-hand or left-hand coordinate system has
been set, the rotation angle direction changes. Check the rotation angle di-
rection before making rotation search settings.
• When Rotation positioning/Coordinate mode/Calibration is set to OFF, the
coordinate system becomes a left-hand system.
• When Rotation positioning/Coordinate mode/Calibration is set to ON, the
coordinate system is determined by the Calibration setting.
