Fig. 6.2: Channel Ch1 encoder configuration (interface X7) screen
This screen is used to select the encoder for channel Ch1. This channel uses the
encoder’s “main interface” to measure position changes periodically and add them
up cyclically – this is referred to as “cyclical evaluation”.
Encoders with a main interface that only makes it possible to measure the cyclical
position incrementally often feature an additional absolute value interface referred to
as an “auxiliary interface”. For this interface, the absolute position is measured once
during the initialization phase and is then used for absolute value initialization
purposes.
