The Feedback n Length attribute is the specified length of a linear absolute
feedback device. Typical linear absolute feedback devices specify length in Meters.
This attribute can be used by the control system to determine the maximum travel
range of absolute feedback device in Feedback Counts, this being the combination
of the feedback cycle resolution, interpolation, and length.
