Commutation signals for sinusoidal commutation

The commutation signals C and D are

taken from the Z1 track and form one sine

or cosine period per revolution. They have a

signal amplitude of typically 1 V

at 1 k.

The input circuitry of the subsequent elec-

tronics is the same as for the  1 V

interface. The required terminating resistor

of Z

, however, is 1 k instead of 120 .

The ERN 1387 is a rotary encoder with

output signals for sinusoidal commutation.
