Thanks! Actually, I'm trying to figure out the actual variables on the 
UT550 - we need to use it to control a motor field current; the input will 
be the output motor speed. For this application, there will be long periods 
of steady-state, and then a BIG change in load, so the second question is 
how will each variable tune the process. I know a lot of that is 
system-related, but it would be nice to have a handle on the starting points.

         Thanks!

PS - This is one of our current projects, .. if there would be any time 
involved.
