Control of "STO" and "SS1" for SINAMICS S150

Description
The safety functions contained in the standard ("Safe Torque Off" and "Safe Stop 1") can
also be used without option K82.
Note
Refer to the circuit diagrams enclosed for the interconnections of your device.
Note
The Safety functions must be activated prior to use via parameter assignment. An
acceptance test must be performed and an acceptance log must be created.
The following Safety Integrated Basic Functions (terms according to DIN EN 61800-5-2) can
be activated:
● Safe Torque Off (STO)
● Safe Stop 1 (SS1) (time-controlled)
Note
The integrated safety functions, starting from the Safety Integrated (SI) input terminals of the
SINAMICS components (Control Unit, Motor Module), satisfy the requirements of
EN 61800-5-2, EN 60204-1 and DIN EN ISO 13849-1 category 3 (formerly EN 954-1), as
well as the requirements for Performance Level (PL) d and IEC 61508 SIL2.
In addition, most of the SINAMICS safety functions have been certified by independent
institutes. A list of currently certified components is available on request from your local
Siemens office.
Recommended application
This variant is used when:
● Activation will be executed optically isolated with a voltage of 24 VDC.
● Working with control lines that are shorter than 30 m.
● Devices are deployed in plants with low spatial elongation (observe the drop in voltage at
24 VDC!).
