I'm using the BLDC motor dev kit (F302R8 + IHM07M1 + BR2804 motor). When I run the Motor Pilot with the SimpleAppMCPV2 to tell the motor to go to a commanded speed, I keep getting a speed feedback fault. Similar thing happens with the MC_FOC UI. The motor starts turning, and runs up to 0.6 amps, then the fault happens and the motor stops turning. I see the feedback speed is in the thousands of RPM instead of the 150RPM I commanded.
I've read that the speed feedback fault might be due to needing to lower the cutoff frequency, so I lowered it from 6000 to 2000 rad/s. But I still get the speed feedback fault.
I'm not sure if there's something wrong with my current feedback config or speed feedback config? This dev kit should be running in sensorless mode (no hall sensors for speed feedback), with FOC.
Here's some of my settings. I'm still new to this, so I don't have a good hunch on what I should be showing. I'm guessing something is the issue with my speed feedback or current feedback config?
