4.2.2 Sensors for speed and/or position detection
4.2.2.1 General safety related structure of the sensor interface for position and/or
speed
The expansion modules of the SMX100 series can be optionally equipped with one (SMX111,
SMX112, SMX121, SMX122) or two encoder interfaces (SMX111-2, SMX112-2, SMX121-2,
SMX122-2) per axis.
Depending on encoder type and combination, different safety levels can be reached. The
following system reflection results for the corresponding partial system:
