4.2.2.1 General safety-related layout of sensor interface for position and/or speed

Different safety levels can be achieved depending on the encoder type and encoder combination. The
safety assessment for the related sub-system is as follows:
Sensor
Sensor
Sensor
Dual-channel sensor system with separate signal processing in two channels, diagnostics by means of cross comparison in the
PES
Sensor system with single and dual-channel sub-system (example incremental encoder). Diagnostics by means of separate
signal processing in two channels and cross comparison in the PES as well as further specific diagnostics.
