System features
4.1 System requirements
● The state of a deleted/clear safety-related input or output (i.e. the state logical "0" of an
SGE/SGA and electrical "low" of an associated I/O terminal) or the state of a drive where
the pulses are cancelled that can be achieved by the user as well by the fault response of
the "SINUMERIK Safety Integrated" system, is defined in what is called the "failsafe state".
This is the reason that the system is only suitable for applications where this state
corresponds to the safe state of the process controlled by SINUMERIK Safety Integrated.
● Drives with slip cannot be used for SE and SN.
● The SINUMERIK Safety Integrated Functions can be used in conjunction with the
SINAMICS booksize and chassis units.
● For the Safety Integrated function, only the explicitly released encoder systems may be
used. A list of the Siemens encoders and motors permissible for Safety Integrated Functions
can be obtained from your local Siemens contact partner.
The following applies specifically for safety functions integrated in the drive:
● A software option is not required when using the SINAMICS Safety Integrated Basic
Functions.
The following specifically applies for failsafe SIMATIC modules:
● STEP7 F-configuration tool (F-Configuration Pack) as supplement to STEP7
This F-configuration tool is required so that ET 200 F-modules or the DP/AS-i F-Link can
be integrated into the HW configuration.
The F-configuration tool can be downloaded from the A&D Service&Support pages under
the topic F-Configuration Pack. Which F-configuration tool can be used for which STEP7
version is also specified there.
http://support.automation.siemens.com/WW/view/en/15208817
When using ET 200 F-modules or DP/AS-i F-Link it should be noted that a version of the
F-configuration tool should be used that the module already supports.
Which modules can be configured with which versions that can be downloaded are also
specified in the download area.
Note
Only the F-Configuration Pack is necessary to connect failsafe SIMATIC modules to
SINUMERIK. Neither SIMATIC S7 Distributed Safety nor SIMATIC S7 F-systems are required.
The following specifically applies for coupled axes:
● In a gantry group, the leading as well as the following axes must be enabled in SINUMERIK
Safety Integrated.
● Also for a master/slave group, SINUMERIK Safety Integrated must be configured on both
axes, assuming that there is no fixed mechanical coupling.
If there is a fixed mechanical coupling, then SINUMERIK Safety Integrated must only be
configured in the master axis.
Based on a risk assessment, the machine manufacturer must evaluate as to whether the
fixed mechanical coupling is adequately stable; if this is the case, then SINUMERIK Safety
Integrated only has to be configured in the master axis.
