Siemens SINAMICS G120C Function Manual

3. Remove the interconnection of the digital input that you use as feedback signal input for
the fail-safe digital output:
– SINAMICS G120 with CU250S-2 Control Unit: Digital input DI 6 (see diagram).
– SINAMICS G120D: Digital input DI 5.
4. If you use the CDS data set switchover, remove the interconnection of the feedback signal
input for all CDS.
