Safety Integrated
Comparison between conventional and integrated safety systems
The safety functions integrated into the drive can greatly reduce
the effort required to implement safety concepts.
The integrated safety functions provide support when setting up
tailored safety concepts. Configurations of safety concepts are
given below based on the example of the SINAMICS G120.
Safe Torque Off (STO)
Conventional wiring
Integrated safety via fail-safe inputs
Integrated safety via PROFIsafe
Safe Stop 1 (SS1)
Conventional wiring
Integrated safety via fail-safe inputs
Integrated safety via PROFIsafe
