AKFEDT-ID
Magnifi cation 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 PEC recognition camera.
The parameters are automatically calculated through teaching
operations performed using the magnifi cation measurement jig.

Default:
2500
Contrast and Brightness
The brightness of the image captured by the PEC recognition camera
can be adjusted.
•
Defaults
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.

The set parameters are used to adjust the positional deviations based on
the design dimensions between the machine reference coordinate origin
and the center of the component recognition cameras.
