Hello,
I am running a BLDC motor in sensorless mode using Nucleo-F101RE with the X-Nucleo-IHM16M1 board. The motor starts successfully when I press the Start button from the Motor Pilot GUI.
However, I am facing the following issues:
When I suddenly increase the speed to high RPM, I get a speed feedback fault.
When I suddenly decrease the speed, I also get a speed feedback fault.
Sometimes I also encounter an overvoltage fault during these speed changes.
Any guidance on how to resolve or tune the parameters properly would be very helpful.
Thank you
Best Regards
Rahul

Hello @Bablu,
For speed feedback fault, review 2.10. Why do I have a Speed feedback fault message chapter in Frequently Asked Questions link.
