The VFD probably won't do any harm but won't tell you much about the encoder/resolver. If you can get your hands on an STMBL drive then you can test properly as it accepts most of the common feedback types (quadrature encoder, resolver and a range of serial data formats) The VFD test won't tell you very much more than you can determine by shorting the power wires in pairs in all combinations and turning the shaft by hand. (tells you if the magnets work and if the coils are open-circuit) -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
