8.1.1 Data Transmission

8.1.1.1 Sine and Cosine Signals
A; /A = Cosine; B; /B = Sine
Each of the signals A, /A, B, /B has an amplitude of 0.5 V
with an offset of +2.5 V against GND.
The analog signals must be measured differentially, i.e. A
minus /A gives Cosine, B minus /B gives Sine. Measured dif-
ferentially, the sine and cosine signals have an amplitude of
1 V , with a phase position of 90°.

8.1.1.2 Recommended Line Termination and
Shielding
A 120 Ω terminating resistor must be connected to the Sine
data line and to the Cosine data line at the input of the
encoder evaluation device.
Otherwise, the characteristic values of the transmission will
change.
In order to ensure independence from manufacturers, we
give the following recommendations for the dimensioning of
the interface:
