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 (safety-relevant).
– 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)
– Safe gearbox stage switchover
– Safely-Limited Acceleration (SLA)
– Safe Brake Test (SBT)

Safe Torque Off is a safety function to avoid unexpected starting in accordance with
IEC 60204-1.
Safe Stop 1 is based on the "Safe Torque Off" function. This allows a Category 1 stop in
accordance with IEC 60204-1 to 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 allows a Category 2 stop in accordance with
IEC 60204-1 to 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.
The "Safe gearbox stage switchover" function facilitates reliable switching between
different gearbox stages. The switchover is only possible via PROFIsafe.
Safely-Limited Acceleration monitors (the same as SLS) the acceleration, and
intervenes when a limit value is violated. SLA cannot prevent that the acceleration
threshold is briefly exceeded.
The diagnostic function "Safe Brake Test" (SBT) checks the required holding torque of a
brake (operating or holding brake).
