Safety Integrated Functions

8.5 Safety Integrated Extended Functions

For the SINAMICS S110 drive system, to perform a self test, a POWER OFF/POWER ON
must be performed for the Control Unit at least once a year. This also applies, if the forced
checking procedure of the safety functions takes place more frequently than once per year.
For SINAMICS S110, the Control Unit can also be supplied from the line connection of the
1)
Power Module. For SINAMICS S110, a POWER OFF/POWER ON means line supply off/on
for the Power Module and – if one is being used – also for the 24V power supply.

Note
You can ask your local sales office regarding the PFH values of the individual safety
functions (also refer to the Section "Probability of failure of safety functions").

Safety functions "with encoder" / "without encoder"

For activation of the Safety Integrated functions "with encoder" and "without encoder", set
the parameters p9306 and p9506 (factory setting = 0). You can also make this setting by
selecting "with encoder" or "without encoder" on the Safety Integrated STARTER screen.
This STARTER screen can be found for each drive under "Functions" → "Safety Integrated".
● Operation with encoder
● Operation without encoder
"Park" mode for Safety Integrated Extended Functions "with encoder"
Note
When a drive object for which Safety Integrated Extended Functions with encoder are
enabled is switched to "Park" mode, the Safety Integrated software responds by selecting
STO without generating a separate message. This internal STO selection is displayed in
parameter r9772.19.
