MARK SIZE D1 (mm), D2 (mm), D3 (mm)
• “D3 (mm)” is reserved data.
Set the outer and inner diameters of a fiducial mark.(Unit: mm)
Refer to “(1) Type and Size” in “2.3.4 P.E.C. Fiducial Marks
of Section 2” for details.
WINDOW SIZE
Set the window size (recognition area) for the P.E.C. recogni-
tion function. (Unit: mm)
Set a preferably small value to avoid false recognition and
shorten recognition time.
MARK DATA
The mark data (code) corresponds to the code No. of the fidu-
cial mark used in the P.E.C. recognition function.
• 10 types of mark codes can be registered for each program
data.
MARK TYPE
Shown is the selected type of fiducial mark.
• Marks are categorized according to the following three types
- “P.E.C. Mark”, “Through Hole”, and “Pad Mark”.

MARK IMAGE
Select one of the following options for a fiducial mark image
(mark pattern) taken by the camera.
“BRIGHT”
“DARK”
BRIGHT : Bright Fiducial/Dark Background
DARK : Dark Fiducial/Bright Background
• Select either mode according to the difference in contrast
between the fiducial and its surroundings.
• Select better mode to get a clear fiducial image.
Note: Wrong mode selection causes malfunction of fiducial
mark recognition.
MARK LEVEL
Select one of the following options as a level to detect a fidu-
cial mark shape.
“HIGH”
“MIDDLE”
“LOW”
HIGH : Both identity and similarity between the shape
of a fiducial mark and the real image are de-
tected on a high level.
MIDDLE : Either identity or similarity between the shape
of a fiducial mark and the real image is de-
tected on a high level.
LOW : Both identity and similarity between the shape
of a fiducial mark and the real image are de-
tected on a low level.
Identity:
Identity between the shape of the specified mark and the real
image (including the size)
Similarity:
Similarity between the shape of the specified mark and the
real image
