Incremental systems with two sinusoidal voltage signals A, B offset by
90 degrees (several, for distance–coded systems) reference mark(s) R.
Transfer:
Amplitude A – *A
Amplitude B – *B
Amplitude R – *R
Power supply:
Max. power supply current:
Max. processable enc. signal frequency:
Note
For the above specified max. encoder signal frequency, the signal amplitude
must be
from the ideal 90
Observe the frequency characteristic of the encoder signals.
