Zettlex encoders have uncommon SSI data formats with leading zeroes or status bits while GraniteCore drives assumes SSI data to begin with position information. Use {{param|FBMT}} to skip those non-position info bits if necessary, and in such case keep {{param|HAP}} disabled. However, if possible, choose Zettlex's SSI3, SSI5 or SSI8 formats which output position data bits first.

If you have tested another kind of encoder, please help us to inform the community by letting us know your encoder model and result by dropping a message into [[Granite Devices support]].
