General information about commissioning safety functions

Commissioning notes
Note
Duplicating safety parameters
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 the SINAMICS
S120 and copy the parameters using the "Copy parameter" button on the start screen of the
safety configuration into the Motor Module.
Note
Drive-specific functions
The "STO", "SBC" and "SS1" functions are drive specific. This means that the functions must
be commissioned individually for each drive.
Note
Incompatible version in the Motor Module
If the version in the Motor Module is incompatible, the Control Unit responds as follows
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 Control Unit triggers a safe pulse suppression via its own safety switch-off signal
path.
• If parameterized (p1215, p9602), the motor holding brake is applied.
• The fault can only be acknowledged after the safety functions were inhibited (p9601).
Requirements for commissioning the safety functions
● Commissioning of the drives must be complete.
● Non-safe pulse suppression must be present (e.g. via
OFF1 = "0" or OFF2 = "0")
If the motor holding brake is connected and parameterized, the holding brake is applied.
● The terminals for "Safe Torque Off" must be wired.
● For operation with SBC, the following applies:
A motor with motor holding brake must be connected to the appropriate Motor Module
connection.
