SPINDLE PHASEDELAY
SD3-0 set the phase delay from BEMF zero crossing to the next commutation.The 30 theoreticaldegree
value can be changedto compensate for switching and other delays that are always present.The delay
adjustmentrange is from1.875 throughto 30 electricaldegreesin 1.875degree increments.
