Commissioning The "Sto", "Sbc" And "Ss1" Functions - Siemens Sinamics S120 Function Manual

Safety Integrated basic functions

9.9 Commissioning the "STO", "SBC" and "SS1" functions

Note
If the test pulses lead to unintended triggering of the Safety Integrated functions, a filtering
(p9651/p9851 SI STO/SBC/SS1 debounce time) of the terminal inputs must be
parameterized.
Overview of important parameters (see the SINAMICS S120/S150 List Manual)

Commissioning notes
NOTICE
For safety-relevant reasons, using the STARTER commissioning tool (or SCOUT) you can
only set the safety-relevant parameters of the Control Unit offline. In order to set the safety-
relevant parameters of the Motor Module, establish an online connection to SINAMICS
S120 and copy the parameters using the "Copy parameter" button on the start screen of
the safety configuration into the Motor Module.
Note
• The "STO", "SBC" and "SS1" functions are drive specific. This means that the functions
• If the version in the Motor Module is incompatible, the Control Unit responds as follows

must be commissioned individually for each drive.
during the switchover to safety commissioning mode (p0010 = 95):
– Fault F01655 (SI CU: Align the monitoring functions) is output. The fault initiates stop
response OFF2.
The fault cannot be acknowledged until safety commissioning mode (p0010 ≠ 95) is
exited.
– The Control Unit triggers a safe pulse suppression via its own safety switch-off signal
path.
– If parameterized (p1215), the motor holding brake is applied.
– The Safety functions cannot be enabled (p9601/p9801 and p9602/p9802).
