It not clear for me, here :
In my case Hall sensor are physically spaced by 60 deg, I am not sure how to setup these 2 parameters.
Any help appreciated.
The displacement is the Hall spacing, and the electrical angle is the equivalent electrical position of the Hall sensor H1 rising edge.
The zero of the electrical angle is the peak of phase A BEMF (OUT1). In your case, I think should be zero, but you should check the motor datasheet.
