I have tried adapting the "Sensorless FOC Motor Control" project of CY8CKIT-037 for the RoboDrive ILM25x04 and it is not working. An error occurs when the speed loop begins. I have followed the Kit Guide and the AN93637 document. I haven't found enough information about PI parameters tuning, but I have tried different values with no positive results.
The motor works fine with the "Sensorless BLDC Motor Control" project, and it has been used in other FOC applications.
I assume the only parameters that should be changed are M_RS, M_LS, M_POLES, M_RATED_SPEED, and M_BASEFREQUENCY. I would like to have more information about the PI controllers so I could change those parameters too. As stated in AN93637, the motor base frequency is Rated_Speed*Poles/(60*2).
The objective of this project is to replace the position estimation with an encoder, but the FOC should work on its own before introducing new components.
Thanks,
Andrés

Hello Andres,
Can you please try step 5. Tune the SMO module if the motor does not rotate [page 40] http://www.cypress.com/file/157806/download
and let us know your observation.
Thanks
