Motor holding brake for servo 2 and servo 3 (parameterizable in the expert list)
● Settings in the Expert list
– Servo2-p1215=3 and Servo3-p1215=3
(3: Motor holding brake as for the sequence control, connection via BICO, no SBC
possible)
● BiCo connections from the sequence control to digital outputs on the Control Unit
– BICO interconnection to "open servo holding brake"
• BiCo in CU_I-p0744: Servo2-r0899.12
• BiCo in CU_I-p0745: Servo3-r0899.12
– Output definition in CU_I
• CU_I-p0728.14 =1
• CU_I-p0728.15 =1

Meaning of the LEDs on the S120 Combi
The SINAMICS S120 Combi has 2 LEDs to display the status. The LED statuses for the
S120 Combi are described in the table below. The status display refers to the internal infeed,
the spindle and the servo drives and the TTL encoder evaluation of the S120 Combi Power
Module

Green Off The component is ready for operation. Cyclic DRIVE-CLiQ
communication is taking place.
-
Orange The component is ready for operation. Cyclic DRIVE-CLiQ
communication is taking place.
The DC-link voltage is present.
-
Red The component is ready for operation. Cyclic DRIVE-CLiQ
communication is taking place.
The DC-link voltage is too high.
Check the line supply volt-
age.
DRIVE-CLiQ communication is being established.
Red - This component has at least one fault.
The LED is activated irrespective of whether the correspond-
ing messages have been reconfigured.
