Yes, but probably no :-) It's a closed-loop constant current supply, with current feedback. And I suspect that there are significant issues with accurately measuring current into an inductive system with electrical and mechanical resonances. Peter Wallace and Jon Elson sell drives of their own manufacture, they might be able to add more technical insight than any sane man needs :-) ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
