3.2.2.2 Double align

Double align can be selected as the startup method when the motor does not have sufficient saliency to detect position using IPD. Also, in applications where the acoustic noise (“chirp”) generated by IPD is not acceptable during startup, it is recommended to select double align as the startup method.
