NCU properties
The Safety Integrated mode of the NCU affects not only the configuration of the integrated
PLC, but rather also that of the integrated drives.
SINAMICS Integrated and NX modules always use automatically the same Safety Integrated
mode as the associated NCU.
Therefore, set this mode in the NCU properties and not in the PLC properties:
Figure 9-5
With the activation of a Safety Integrated mode, the F-capability of the PLC is set appropriate
for the Safety Integrated mode of the NCU.
