Why does the motor turn left and right twice at the beginning when I call the closed loop program? #310

Hello, why is it that when I call a closed-loop program, the motor rotates two times from side to side at the beginning? Is it calibration? Can you cancel it?

This is the calibration required to find the electrical zero point.

After you have run it once, you can re-use the values found by remembering them and passing them to motor.initFOC(). Please see our documentation for further details.

Thank you for your reply and I wish you all the best.
