These functions require an additional safety license. Extended Functions with encoder
require an encoder with safety capability.
– Safe Torque Off (STO)
Safe Torque Off is a safety function that prevents the drive from restarting
unexpectedly according to EN- 60204-1.
– Safe Stop 1 (SS1, time- and acceleration-controlled)
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 (SBC)
Safe Brake Control safely controls a holding brake.

– Safe Operating Stop (SOS)
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 (SS2)
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 (SLS)
Safely Limited Speed monitors that the drive does not exceed a preset speed/velocity
limit.
– Safe Speed Monitor (SSM)
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 (SDI)
Safe Direction is used to safely monitor the direction of motion.
– Safely-Limited Position (SLP)
Safely-Limited Position ensures that a freely definable traversing range is not left.
– Transferring safe position values (SP)
The "Transfer safe position values (SP)" function enables you to transfer a safe
position to a higher-level controller via PROFIsafe.
– Safe gearbox stage switchover
The "Safe gearbox stage switchover" function facilitates reliable switching between
different gearbox stages. The switchover is only possible via PROFIsafe.
– Safe Brake Test (SBT)
The diagnostic function "Safe Brake Test" function (SBT) checks the required holding
torque of a brake (operating or holding brake).

Note on Power/Motor Modules with chassis format:
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.
