The feedback board is used to receive feedback from the resolvers on the
1326 motors and from external encoders. The full 9/440 resolver--based
control can support up to six feedback devices (any combination that does
not exceed a maximum of four resolvers or a maximum of three encoders).
For example 3 resolvers and 3 encoders or 4 resolvers and 2 encoders.
