Resolver interface using C2000 micro controller for position and speed measurement.

Other Parts Discussed in Thread: TIDM-02014, CONTROLSUITE, C2000WARE

Hi there, I'm using the Tamagawa 5X resolver, TS2620N1095E161 for position and speed measurement. Can you suggest a way to interface this with any C2000 microcontrollers? any reference circuit/schematic to extract the angle from the resolver output (Sine and Cosine) will also be helpful. The resolver output will be a combination of high-frequency excitation and rotor sine angle wave, how to I extract the envelope from there and get angle details?

Thank you.

Hello,

For resolver:

There is a resolver as part of TIDM-02014 (https://www.ti.com/tool/TIDM-02014) - I suggest taking a look at the schematics of this design for an example analog front-end.
TMDSRSLVR SW can serve as a code example (C:\ti\controlSUITE\development_kits\TMDSRSLVR_v1.0\Resolver_f28335).
Unfortunately this hardware (TMDSRSLVR) has been discontinued. But you may find some of the documentation on the product page helpful: https://www.ti.com/tool/TMDSRSLVR

For sin/cos we have this application note:

There is some sample code in ControlSUITE for the F2837xD family. Unfortunately it hasn't been migrated to C2000Ware.

Regards,

Lori
