Overview of the Hardware Configuration (Minimum Configuration)
The following hardware components are used:
SIMOTION/SINAMICS drive system
■ sin/cos encoder
■ SMx20 encoder module (the figure shows both - SMI20
and SMC20)
■ Fail-safe Distributed Safety System
These components have to be connected using the appropriate
signal cables (see following figure).
Hardware components
1. The SIMOTION drive system and the fail-safe Simatic CPU
must be connected via a bus cable.
2. The SH in the drive system is controlled by the F-CPU via
terminals.
3. According to enumeration item 2, a fail-safe output module
of the fail-safe Distributed Safety System has to be
used.
4. At least one fail-safe input module of the fail-safe
Distributed Safety System must be provided for signals
such as protective doors, acknowledgement buttons, etc.

5. In addition to this, the SH checkback signal transferred
within the drive system has to be connected to a digital
output which must then be connected to a digital SIMATIC
I/O input. This input can be implemented as a fail-safe input
or standard input since the checkback signal output by the
safe stop has been implemented as a standard function
rather than a safety function.
This document describes the example of a IM151-7 F-CPU
equipped with fail-safe ET 200S I/O components. These components
can be replaced by Distributed Safety System components
with identical functions.
