General information about SINAMICS Safety Integrated
3.1 Supported functions
● Safety Integrated Extended Functions
These functions require an additional safety license. Extended Functions with encoder
require an encoder with safety capability.
– Safe Torque Off (STO)
– Safe Stop 1 (SS1, time- and acceleration-controlled)
– Safe Brake Control (SBC)
– Safe Operating Stop (SOS)
– Safe Stop 2 (SS2)
– Safely-Limited Speed (SLS)
– Safe Speed Monitor (SSM)
– Safe Direction (SDI)
– Safely-Limited Position (SLP)
– Transferring safe position values (SP)
– Safe gearbox stage switchover
– Safe Brake Test (SBT)
Note on Power/Motor Modules with chassis format:
1)
For chassis format, SBC is only supported by Power/Motor Modules with article number
...3 or higher. A Safe Brake Adapter is also required for this design.

Safe Torque Off is a safety function that prevents the drive from restarting
unexpectedly according to EN- 60204-1.
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.
Safe Operating Stop protects against unintentional movement. The drive is in closed-
loop control mode and is not disconnected from the power supply.
Safe Stop 2 safely brakes the motor with a subsequent transition into the "Safe
Operating Stop" state (SOS). This means that a Category 2 stop according to EN
60204-1 can be implemented.
Safely Limited Speed monitors that the drive does not exceed a preset speed/velocity
limit.
Safe Speed Monitor safely identifies when a speed limit is undershot in both directions
of motion, e.g. to identify zero speed. A fail-safe output signal is available for further
processing.
Safe Direction is used to safely monitor the direction of motion.
Safely-Limited Position ensures that a freely definable traversing range is not left.
The "Transfer safe position values (SP)" function enables you to transfer a safe
position to a higher-level controller via PROFIsafe.
The "Safe gearbox stage switchover" function facilitates reliable switching between
different gearbox stages. The switchover is only possible via PROFIsafe.
The diagnostic function "Safe Brake Test" function (SBT) checks the required holding
torque of a brake (operating or holding brake).
