"@" taught position symbol

This is not really a big deal, more of an annoyance than anything. But I noticed when I reach a position and drop motor power the "@" position symbol will turn off. Watching the position screen you can see the numbers slightly change, but I am wondering which variable is it that controls this and is there a way to up the tolerance? These are brand new fanuc's.

Factory default is 30.000. I bumped it up some to see if there would be a possible change. Restarted the robot and nothing changed as far as the "@" symbol staying on.
