2.1.4.6 Functional Description

Typically, incremental encoders supply two output signals of the encoder
track, both 90° offset. These signals are designated A and B. The difference of
the input signals is evaluated in the incremental encoder I/O module.
Usually, incremental encoders have an index track in addition to the two track
signals. This index track only produces one pulse per one full encoder revolu-
tion. This pulse and the counter reading can be used to determine the absolute
encoder position during rotation. The index pulse has a duration of a track po-
sition pulse. We recommend to always have the latch process performed in the
same rotational direction.
