Well, in that case you probably want to use "comp" as you already are. That's unidirectional. But you are saying that you want to have the trip threshold proportional to speed. The way to do that is probably to pass spindle speed feedback into sum2 (noting that sum2 has gain and offset, so you can play games like sum2 spindle-speed and spindle speed * -0.1 to have 90% of spindle speed on the output. ) -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ LogMeIn Rescue: Anywhere, Anytime Remote support for IT.
