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 basic modules of the PSCBR series can be optionally equipped with one (PSCBR-C-10-
SDM1/12) or two encoder interfaces (PSCBR-C-10-SDM1-12/12-2) per axis.
Depending on encoder type and combination, different safety levels can be reached. The
following system reflection results for the corresponding partial system:
