Posted on July 15, 2018 at 21:29I have the NUCLEO-IHM07M1 motor dev board along with the NUCLEO-F302R8 mcu dev board. I've tried to get the demo software working with the ST Motor Control Workbench but am getting a Speed Feedback fault each time I try and start the motor. I'm able to connect to the dev board in the workbench, see the correct bus voltage, etc. But as soon as I start the motor, the rpm gauge goes all over the place for a bit before reporting the fault. Almost as if there are floating inputs to hall sensors or something. I've read through as much documentation as I can find and I am reasonably confident I have the sw and jumpers configured correctly for FOC control. Any ideas what could be causing this fault?
Thanks
