Hi Andy,
Well it is a bigIF for one STMBL ;) Do you have one to spare?
These are fitted with resolvers so STMBL would be nice.
I have 7 motors to be checked.
VFD test might reveal if there is some mechanical issues such as bearings.
Cheers
Bengt

What do you want to test?
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)
