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

Safely Limited Speed (SLS)

Conventional wiring

Integrated safety via fail-safe inputs

Integrated safety via PROFIsafe
