Safety position, standstill, direction and speed detection
https://support.industry.siemens.com/cs/document/49221879/

Operators must be protected from hazardous machine movements. In many cases, this requires reliable standstill detection. A safe speed limit may be required for service and setup operations. However, dangers can also arise from approaching a prohibited position. How can the safety detection of machine movements be carried out reliably?

SIEMENS offers drives with integrated safety functions (e.g. SINAMICS S210) for safe detection of machine movements for a wide range of applications.

Another possibility is the use of safe position encoders (also referred to as F-position encoders). In conjunction with a SIMATIC F-CPU, safely acquired values of the F-position encoder can be processed further and corresponding reactions initiated.

This application example describes the use of such an encoder.

F-CPU and F-position encoder communicate with each other via PROFINET. The safety-relevant data is exchanged via the PROFIsafe bus profile via the same bus cable as the standard data.

The application example shows you how to easily integrate an F-position encoder on PROFINET. With the F-CPU, you can then implement a number of safety-related topics. The following topics are presented in this example:
Safe standstill detection
Safe velocity sensing
Safe direction sensing
Safe position detection
Safe preset adjustment of the safe position
Providers of failsafe position encoders are, for example:

TR Electronic GmbH www.tr-electronic.com
TWK-ELEKTRONIK GmbH www.twk.de/en
This example was implemented with the safety-related position encoder CDV582M from TR-Electronic (SILCL 3 / PL e / Cat 4).
These described applications comply with a safety integrity level up to SIL 3 according to IEC 62061 bzw. PL e according to ISO 13849-1.
