Hi

I'm working with the STM3240G-EVAL Board and trying to drive a BLDC Motor from Maxon EC-max 30 type 339923 (maxon.com) On the motor side I have Hall sensors and an encoder with 500impulses / turn, 2 channels A+B and the Z channel. I used the ST Motor control workbench to set the parameters and IO PINs. Target Lib is SDK v3.4. I'm wondering why I don't need the HALL sensor signals to detect the correct angle of the motor. My problem is now, that I have not a sine current on the motor phases and i can't change the speed of the motor... How can I tune the PID parameters from the speed controller and the PID parameters of the clarke and park transformation? I really need help as soon as possible because I need to getting run with this motor as soon as possible. I hope that anyone can help me. The Plot from the oscilloscope is from the turning motor, the yellow CH1 is the Hall sensor signal from the phase U of the Motor, CH2 = U, CH3 = V, CH4 = W. Best regards, Dominik
