The reaction function that takes place (e.g. shutting down the drive, activating a mechanical
brake) when exceeded limit values are detected during the normal operation of the safety
function must be defined and implemented by the machine/plant developer and does not
form part of the PNOZ s30.
The monitoring function of the PNOZ s30 can be used to implement safety functions de-
fined in the standard EN 61800-5-2 for Adjustable speed electrical power drive systems.

Safety-related architecture
To calculate the safety function you will need the following data for the "sensor" subsystem
and "PNOZ s30" subsystem:
Sensor PNOZ s30 subsystem
Category MTTFd DC Operating mode PFH (1/h)
1* Manufactur-
er-specific
0 % Monitoring
1 encoder
2,34-08
*In accordance with EN ISO 13849-1, Category 1 is only met if the sensor is a "well-tried
component".
