I have created ioc project using MCSDK 6.1 for steval-spin3201 board to control a BLDC motor in sensorless PLL mode and/or HALL sensor mode. I have used ST Cube MX to generate Cube IDE project files , build them and downloaded executable files to the board. I have used ST Pilot program to communicate with the board . I was able to start and stop the motor but I could not make the motor run at the speed that I have set. Motor actual speed oscillates in a very wide range around the value that I have specified. It seems to me , speed regulation ( closed loop operation) does not work .
