Chapter 8 Home an Axis
Saving an ACD File Versus Upload of a Project
The following is an example of a sequence of events that can generate an APR
fault.
1. Make an online change to an axis attribute that generates an APR fault.
2. Rehome the axis.
This is normally done so APR will restore axes positions after a download.
3. Save your project.
4. Download your project.
You still get an APR fault because saving the project only uploads the tags,
not the changed attributes.
IMPORTANT
You must upload the project for the changed attributes to be
saved and to prevent an APR fault on a subsequent download.
