Z (Angle) [deg]
Set the parameters representing the angular deviations in the scanning
coordinates of the component recognition cameras based on the
machine reference X/Y coordinates (Xm-Ym).
When the camera scanning coordinates are shifted counterclockwise
to the machine reference X/Y coordinate system, a plus sign must be
affixed to each offset data.

Magnification X (Horizontal) and Y (Vertical) [0.01 mm/pixel]
Set how many micrometers should be equivalent to one pixel to specify
the magnifi
cation of the component recognition camera.
The parameters are automatically calculated through teaching
operations performed using the magnification measurement jig.

Contrast and Brightness
The brightness of the image captured by the component recognition
camera can be adjusted.
•
Default
Contrast :
102
Brightness
: 128
Note
(a) The larger the value for "Contrast" is, the stronger the chromaticness
becomes.
(b) The larger the value for "Brightness" is, the brighter the whole view
becomes.

[3] Fly Recognition XY
X (Horizontal) and Y (Vertical) [mm]
Obtain the deflections (caused mainly due to the delay time of the
servoamplifier and the strobe) of the images captured by the stopped
component recognition camera (still image capture) and the flying
component recognition camera (fly image capture) and set the obtained
values to adjust the deviations in timing for image capture.
The set parameters are used to prevent a component from getting
af
fected by the delay and staying out of camera field of view.
