So I am running my ODrive in sensorless mode and I seem to have hit an RPM cap. If I run the motor at 28000 RPM everything works fine. When I try to run the motor at 30000 RPM it hit about 28300 RPM and will not go any further. At the same time the Iq_setpoint will start to ramp up. At 28000 RPM it will be at 2A. At 30000 RPM it will go up over the course of about a second to 20A. At the same time the measured current wont get above 4A.
I know this motor can go faster than this. The manufacturer runs it at 18V and can hit 30000 RPM no problem. I am hoping the issue is that I need to tune the motor settings. I have no idea how to do this though.
Here is a CSV with data I logged:
