Encoder systems that can be evaluated

Incremental
Incremental systems with two 90-degree offset sinusoidal voltages signals A, B
measuring and a reference mark R.
E.g. ERN 1387 (motor measuring system)
systems
Transfer:
Amplitude A – A
Amplitude B – B
Amplitude R – R
Power supply:
Maximum supply current:
Max. encoder signal frequency
that can be evaluated:
Note
For the above frequency, the signal amplitude must be  60 % of the typical
amplitude and the deviation of the phase offset from the ideal 90
track A and B must be   30
Pay attention to the frequency characteristic of the encoder signals.
