8.7 Connection to the evaluation unit
The maximum sampling frequency f
A,max
, at which a new
current value is available with each sampling, can be found
in the following graphic:
Fig. 8-1: Maximum sampling rate depending on the nominal length
(for position output) The maximum sampling rate for velocity
output is limited to 3.3kHz.
The maximum SSI clock frequency f
