Accuracy
Maximum Output Frequency
Shaft encoders have three defined types of accuracy. In each case the
accuracy is given asa%ofthepulse length, which consists of a pulse
and a pause.
The partition error is defined as the deviation of any pulse edge from its
exact geometric position and as standard is a max 12%.
The pulse/pause ratio describes the ratio of the pulse/pause deviation
from the pulse length.The accuracy value has been given for each
encoder and as standard amounts to a max ± 7.5%.
The phase displacement describes the accuracy of two successive
edges. The accuracy is given for each encoder and as standard
amounts to a max. 7.5% of a pulse length.
The maximum output frequency is given for the various encoders. For
limiting factors such as cable lengths and diameters, please see the
section on cable lengths. When designing the electronic evaluation
circuitry for maximum frequencies and noise suppression, tolerances
should be taken into account in order to provide a safety margin so as to
handle maximum output frequencies which may occur in the specific
application.
The maximum occurring frequency f can be calculated using the
following formula :
f(max) in Hz = ( max shaft speed in RPM) x (pulses per revolution PPR)
