Parameter settings for ADA4571 amr encoder

Post by Adrianbb »

Hello, I searched a lot, but I didn't find any clear answer to my question. I´m running sine OI firmware and have ada4571 amr encoder. I'm not sure how to set correct parameters.

It have two sine waves per 360° revolution. Output amplitude is 0,875V - 2,545V, so mid point is 1,71V and sincos offset is set to 2122. I think that is ok.
Encoder set to sincos, but what about resolver pole pairs? If here are two sinewaves per revolution, then correct setting is 2?
Thank you.
