Safety-related architecture

To calculate the safety function you will need the following data for the "sensor" subsystem
and the subsystem "PSSu K F EI":

9.1.5 Safety-related characteristic data for operation with non-safety-related
encoder with diagnostics via the drive controller
The detection of sensor errors (diagnostics for the sensor subsystem via the evaluation
device) can be supplemented with a drive controller.
