Note
For synchronous spindles, the field angle should be determined via the
code number, since this is a more exact determination.
Danger
 An encoder with absolute values or an encoder with a Z1 track must be
used when determining the field angles for hanging axes (or braked axes
that could move on their own).
 If the speed encoder is exchanged, the Field Orientation function must
be rerun.
