SPINDLE PHASE DELAY
SD3-0 set the phase delay from BEMF zero crossing to the next commutation. The 30 theoretical degree
value can be changed to compensate for switching and other delays that are always present. The delay
adjustment range is from 1.875 through to 30 electrical degrees in 1.875 degree increments.
