Hello,We have a 5 pole pair magnet rotor and we have been using STEVAL-CTM009V1 development kit along with NUCLEO-G474RE development board.First, we did a preliminary testing with a sensorless control (observer+PLL) and after understanding the aspect...

Hello @GMA ,Any updates on how to resolve this? It's been a while since I heard from you.Please let us know if you have anything in mind that we could try.

Hello @GMA ,As suggested we set our H1, H2, H3 as per the first trial and interchanged U & V. By doing so the motor spun in opposite direction and both 'STO_EL_Angle' and 'Hall_EL_Angle' followed the same pattern but weren't aligned. The Placement el...

Hello @GMA ,Yes, Precisely. That's the setting I used.As I had mentioned earlier we did all the necessary steps as provided in the Launch Workbench 6.1.2 -> About -> Documentations -> User Manual -> Hall sensor feedback processing.

Hello @GMA ,Sure, Below are the snaps of the oscilloscope for the Hall Feedbacks. Img1: Main: STO-PLL, Aux: Hall. This is while the motor is spinning Img2: Main: Hall. (motor isn't spinning, hence no change in the Hall states. H1-1, H2-0, H3-1). Plea...

Hello @GMA ,Yes, I anticipated that would be the outcome if my HALL sensors are misaligned. So I did observe if there are any changes in the "Mechanical Speed" and yes, I do get to see the speed changes in the mechanical speed without any Speed Feedb...
