There are two ways to achieve this that I have seen. The first is a limit on P + I. So, if P is high then I is limited, and for very high errors I is limited to 0. Another thing I have seen (generally configurable as it is often decidedly _not_ the thing you want) is an option to zero the I term when the error crosses zero. -- 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.
