Part detection can be performed when Source in the Trigger panel is set to Time or Encoder. To use
the Time trigger source, the travel speed must be calibrated. To use the Encoder trigger source, the
encoder resolution must be calibrated. See Aligning Sensors on page 126 for more information.
Multiple parts can pass through the laser at the same time and will be individually tracked. Parts can be
separated along the laser line (X axis), in the direction of travel (Y axis), or by gated external input.
The following settings can be tuned to improve the accuracy and reliability of part detection.
Setting Description
Height Threshold
Determines the profile height threshold for part detection. The setting for Threshold
Direction determines if parts should be detected above or below the threshold. Above is
typically used to prevent the belt surface from being detected as a part when scanning
objects on a conveyor.
In an Opposite layout, the threshold is applied to the difference between the top and the
bottom profile.A target thinner than the threshold value is ignored, including places
