An example of a single-ended device is a single-ended encoder.
A single-ended encoder has phase A, phase B, and index signals.
Use the phase A signal to meas
u
re rotational speed. Use the
phase B signal to meas
u
re direction. Use the index signal to
meas
u
re the n
u
mber of rotations.
Connect each of the signals of the encoder (phase A, phase B,
and index) to a DI pin. Fig
u
re 5 shows the connections for
one single-ended encoder.
