Chapter 5: Configuration with ACE Software
NOTE:
ACE 3.7.3.150 or later is required for support of all four AnyFeeder models.
You can position the AnyFeeder within the ACE 3-D visualizaion, so that it matches how your
AnyFeeder is actually installed.
You also have the opportunity to test the backlight, if your AnyFeeder has one.
Teach Pick for Arm- or Fixed-Mount Camera
This step includes creating a camera object, setting the camera properties, performing a grid
calibration, teaching a Locator Model and picture position. It will then step you through loc-
ating an instance of the object, teaching the pick position, and performing an automatic cal-
ibration. It ends with a calibration summary and teaching a vision histogram tool.
l
Make sure your part is well lit. It is better to have more light and a lower exposure.
l
In the Virtual Camera, under Acquisition Settings, edit the current settings. Under Video
Format, ensure that the exposure is set to a low value to reduce blur.
l
Adjust the lens aperture and focus of your camera until you obtain a good image.
l
When focusing the lens, using a sheet of printed text at the height of the part is often the
best way to get the focus correct.
l
You may also need to edit the Acquisition Settings to get the best image.
Using the Calibration Grid
A pdf of the dot grid, used for camera calibration, is located in your Omron folder under Pro-
gram Files. Use the file DotPitch10_CalibrationTarget.pdf in the ACE folder.
l
Calibration establishes the mm/pixel ratio of the field of view of the camera and com-
pensates for lens distortion.
l
Make sure your calibration grid is printed to scale. The actual pitch between the dots
must match the nominal pitch in both directions. Specifically, in the printer settings,
you must make sure the grid is printed at actual size and not to fit or shrunk. For the
AnyFeeder SXM100 and SXM140 you will have to trim some of the paper off after print-
ing for it to fit inside the feed surface. This will not affect calibration.
l
When you place it under the camera, it should fill the entire field of view. It must also
be flat over its entire surface.
l
Ensure that the height of the dot-grid matches the height of the parts being picked in the
field of view. The closer the lens is to the part and the tighter the tolerances, the more
critical this becomes.
l
Do not change the lens settings, either the focus or aperture, after calibration.
l
Calibration can be performed in the virtual camera object or during the addition of a
camera to a workspace.
