    Does anyone know where to find the early Motion Link version for mid 1990's VFS5 drives? A DOS application, apparently.

    Right... progress! I managed to set the axis modulus correct.

    Done some more fiddling;

    Display shows 1.3 degrees per motor revolution, so the resolver seem to work. The ratio might be off, though.

    Hi meckardt55!

    It's the other way around in my case; the servomotor has an encoder installed, so I must get hold of a suitable resolver to replace the encoder.
