General information about SINAMICS Safety Integrated
1.1 Supported functions
● Safety Integrated Extended Functions
Note regarding Power/Motor Modules in chassis format:
1)
For the chassis format, SBC is only supported by Power/Motor Modules with order number
...3 or higher. A Safe Brake Adapter is needed in addition for this design.
Note regarding Power/Motor Modules in blocksize format:
2)
blocksize Power Modules additionally require a Safe Brake Relay for this function.

These functions require an additional Safety license: Extended Functions with encoder
require an encoder with Safety capability (see section "Reliable actual value acquisition
with encoder system").
– Safe Torque Off (STO)
Safe Torque Off is a safety function that prevents the drive from restarting
unexpectedly in accordance with 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 in accordance with EN 60204-1 can be implemented.
– Safe Brake Control (SBC)
Safe Brake Control is used to safely control a holding brake.
– Safe Stop 2 (SS2)
Safe Stop 2 is used to safely brake the motor with a subsequent transition into the
"Safe Operating Stop" state (SOS). This means that a Category 2 stop in accordance
with EN 60204-1 can be implemented.
– Safe Operating Stop (SOS)
Safe Operating Stop is used to protect against unintentional movements. The drive is
in closed-loop control mode and is not disconnected from the power supply.
– Safely Limited Speed (SLS)
Safely Limited Speed ensures that the drive does not exceed a preset speed
limit/velocity.
– Safe Speed Monitor (SSM)
Safe Speed Monitor is used for safely identifying when a speed limit is fallen below in
both directions of motion, e.g. to identify zero speed. A fail-safe output signal is
available for further processing.
– Safe Acceleration Monitor (SAM)
Safe Acceleration Monitor (SAM) is used to safely monitor drive acceleration.
– Safe Direction (SDI):
Safe Direction is used to safely monitor the direction of motion.
