Hi Dylan, We still face two problems in driving the motor. https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1459067/mspm0g3507-when-the-motor-operates-the-voltage-current-speed-information-is-incorrect https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1456880/mspm0g3507-full_scale_current_base-does-not-work-as-calculated/5599623#5599623 So we are still only running in open loop and not working normally in closeloop. In this state, if I do it the way you suggested above, I can see the function definition and the motor runs in the openloop. Please let me know if there are any differences with sensorless in the motor drive algorithm. Until then, I'll be using this code. B.R. Donguk
