RDE
Most closed-loop motors controllers require the incremental quadrature feedback that
encoders provide. Empire Magnetics' RDE resolver-to-digital converter module closes the
loop betwen rugged feedback resolvers and motor controllers that require encoder feedback.
RDE converters connect easily to Empire Magnetics resolvers, providing complementary
TTL compatible two phase quadrature and outputs with index (Channels A, B, and Z).
For a more detailed look
at the specifications, consult the RDE
Manual.
