Obviously safety must be considered; you don't want people entering the field believing that your machine has come to a resting position when it is about to lift or actuate any mechanism.

That being said, we have discussed options of using pneumatic valves that will switch when powered off to trigger any number of mechanical operations. Given that everything else should come to a static position with a second or two it is probably best if any continuing activity would be obvious in this time frame and not have any considerable delays.
