Thanks for responding.
It is belt-driven. We have a MARS 48v, with 2:1 pulley reduction with dual belts from the big pulley to the small pulley on the motor shaft.
Unless the Sevcon PMAC is set up differently for forward vs. reverse, I don't see why the motor would care which way it's spinning. I just want to be sure i'm not going to damage anything.
