Note: There is no upper speed limit for the absolute outputs. With increasing speed, the distance between two samples increases. The trav-
elling distance between two subsequent samples can be calculated as:
v
fs
where:
sampling_distance = travelling distance between samples in mm
v = travelling speed in mm/sec
fs = sampling rate in Hz
Pole crossings need to be tracked to calculate absolute position beyond one pole pair. The ability to differentiate pole crossings may be
a speed limiting factor in such cases.
