Still having MOTOR _ERROR _UNKNOWN _PHASE_ESTIMATE error on restart, even after working fine before restart

So I am still struggling with getting these RW170 motors to work with Odrive.

I have an Odrive 3.6 on a 24 volt supply.

It is set to start on closed loop control, and I’ve added an index. I can calibrate and run perfectly, but when I save the configuration it always comes up not working, with this error.


I had thought before the problem was because I had no index, just AB on the encoder, but I added one and while it does find it during calibration and runs great, it will not continue working after restart.

You have to do an index search every time you restart the odrive by setting the state to ENCODER_INDEX_SEARCH
