(7) PCB Cut Offset
When the P.C.B. has a cutout at its edge and must be posi-
tioned against the P.C.B. stopper, enter the depth of the cutout
in the text box.
Unit : mm
1.2.4 P.E.C. Recognition
(1) P.E.C. Recog. Function
Only "2-Point Recognition" is performed.
(2) Center Recognition
It can be selected whether or not the machine should perform
the center recognition.
ON : The machine performs the center recognition.
OFF : The machine does not perform the center recognition.
When the center recognition function is used, a fiducial mark is
recognized once and the camera is moved to the position
where the recognized fiducial mark is located at the center of
the visual field. After that, the fiducial mark is re-recognized.
The positional accuracy is improved because the mark is
recognized at the center of the visual field (the spot of the lens
with less distortion).

(3) Fiducial Mark #1
X [horizontal] and Y [vertical]
Set the coordinates of the first fiducial mark.
Unit : mm
Recog. Mode
Select the recognition mode.
Mark :
This recognition mode uses fiducial marks.
Model :
The image taken with the recognition camera is regis-
tered as "Model".
This mode uses the "Model" in place of fiducial marks.
Model + Mark :
This mode recognizes the image in the center of the
model as in the mark mode, after rough positioning with
the model mode.
Code
Set the code No. of the first fiducial mark.
Auto Gain Adj.
Select whether or not the automatic gain is adjusted when the
PEC recognition is tested.
ON : The automatic gain adjustment is performed.
OFF : No automatic gain adjustment is performed.
Gain, Level
This sets the amplification rate, when the signal of the image
(taken by the PCB recognition camera) is converted to image
data showing brightness.
• When the gain is decreased, the contrast becomes
greater.
• When the level is decreased, all of the brightness be-
comes greater.
Calib. Lamp
Normal : Selected when the contrast between fiducial mark
and PCB surface is adequate.
Ring : Selected when the gold-plated mark is used for
fiducial marks.
Both : Selected when the silver-plated mark is used on the
ceramic PCB and there is slight contrast between
the colour of the PCB surface and the fiducial
marks.

(4) Fiducial Mark #2
X [horizontal] and Y [vertical]
Set the coordinates of the second fiducial mark.
Unit : mm
Recog. Mode
Select the recognition mode.
Mark :
This recognition mode uses fiducial marks.
Model :
The image taken with the recognition camera is regis-
tered as "Model" using the "Position Teaching" tab. This
mode uses the "Model" in place of fiducial marks.
Model + Mark :
This mode recognizes the image in the center of the
model as in the mark mode, after rough positioning with
the model mode.
Code
Set the code No. of the second fiducial mark.
