Posted on May 18, 2018 at 08:46I would like to run the Sensorless FOC firmware with a PWM frequency greater than 65kHz.My hardware configuration:Nucleo-F446RE -> X-Nucleo-IHM09M1 -> Custom power-stage with ICS current sensors and bus voltage measure...

Posted on July 09, 2018 at 22:00Giuseppe,I have made the changes, and tested with my hardware.The motor starts and runs with PWM_FREQUENCY = 167kHz and REGULATION_EXECUTION_RATE = 3. However, if I increase the PWM_FREQUENCY above this, I get an FOC_...

Posted on June 24, 2018 at 03:25Giuseppe,I will give this a try. However, while this will allow the PWM_FREQUENCY to be >65kHz, the the TF_REGULATION_RATE will still need to be <65kHz because it is still cast as uint16_t.For my application, where I ...

Posted on June 15, 2018 at 01:52Cedric,My target hardware configuration is an STM32F446RE running at 180MHz. The power stage uses three LMG3410-HB-EVM modules, with a target PWM frequency of 175kHz and 50ns dead time. Phase current measurements are ...

Posted on June 13, 2018 at 04:10Hi PBo,I'm reluctant to move away from the SDK4.3, as I have the configure-build-upload chain working comfortably. However, one of the first things I did was check whether SpeedNPosFdbkClass.h and VirtualSpeedSensor_S...

Posted on April 14, 2018 at 12:56I had a very similar problem, but using a STM32F302R8 NUCLEO board. However, when I used a STM32F303RE NUCLEO board with the same IHM08M1 power stage, I was able to run the motor-profiler. Because the F303 and F302 m...
