8.6 Focus Change (Initial Focus Position)
When the thickness of the Workpiece is changed after Alignment has been
taught (for example, change in the tape thickness), instead of reteaching
Alignment, there is a simpler and faster process of updating the Initial
Focus Shift parameter (Align category). This parameter specifies a
position of the Z-Axis that provides an acceptable default focus.
To Teach the Initial Focus Shift:
1 Click to display the Programming Workspace.
2 Expand the Recipe assigned to the Workpiece in the Programming tree
and select the Align parameter category of that Recipe. The parameter
table for the Recipe is displayed on the right.
3 In the General tab of the parameter table, scroll to the Align category,
in the Programming tree, and click the cell containing the value
defined for the Initial Focus Shift parameter. The Teach Parameter
button becomes enabled.
4 Click Teach Parameter.
5 In the Wizard area of the Video Workspace, click Next.
6 Using the Z/T Axis Controls, set the optimal focus for the Camera.
Click Finish. The Focus Position is now taught.
7 Click Yes to save the parameter to the Recipe.
Note: This effect all the Z-Axis focus values, such as focus for models, etc.
