Fail-Safe Digital Input - Siemens SINAMICS G120 CU240B-2 Operating Instructions Manual

5.2

Fail-safe digital input

This manual describes "Basic Safety", i.e. the STO safety function with control via a fail-safe
input. Additional safety functions and additional fail-safe digital inputs of the inverter
("Extended Safety") are described in the Safety Integrated Function Manual. You will find the
link to the Safety Integrated Function Manual in Section Overview of documentation
(Page 13).
Assignment of the fail-safe digital input
If you activated the inverter safety functions, the inverter combines digital inputs DI4 and DI5
to form a fail-safe digital input.
