Changes made for Pathfinder 5226 controllers.

All axes that have some kind of feedback will have error checking for if the target is further out from the maximum position parameter or if it is less than the minimum position parameter. So once the axis is setup with its feedback matching up to the physical world the axis should be safe and not crash into anything. One problem though is if there is a failure to the feedback device. In this case the axis might act in a non-normal way.

The fix for this was to have each axis have a set in stone travel range that gives some leeway for the axis saying its outside the minimum and maximum positions, but will error out if beyond this range. This check happens before an axis is about to make a move.
