Supported functions

All of the Safety Integrated functions available under SINAMICS are listed in this section.
SINAMICS makes a distinction between Safety Integrated Basic Functions and Safety
Integrated Extended Functions.
The safety functions listed here are in conformance with:
● Safety Integrity Level (SIL) 2 according to IEC 61508
● Category 3 according to DIN EN ISO 13849-1
● Performance Level (PL) d according to DIN EN ISO 13849-1
The safety functions correspond to the functions according to DIN EN 61800-5-2 (under the
assumption that they are defined there).
The following Safety Integrated functions (SI functions) are available:
● Safety Integrated Basic Functions
These functions are part of the standard scope of the drive and can be used without
requiring an additional license. These functions are always available, and do not require
an encoder and/or do not place any special requirements on the encoder used.
– Safe Torque Off (STO)
– Safe Stop 1 (SS1, time-controlled)
– Safe Brake Control (SBC)

Function Manual, 07/2016, A5E03264275A
Safe Torque Off is a safety function to avoid unexpected startup in accordance with
EN 60204-1. STO prevents the supply of energy to the motor which can generate a
torque and corresponds to Stop Category 0.
Safe Stop 1 is based on the "Safe Torque Off" function. This means that a Category 1
stop according to EN 60204-1 can be implemented.
Safe Brake Control safely controls a holding brake.
