SI MM: Sign–of–life error in safety data
OFF2
IMMEDIATELY (POWER ON)
The "Safety Integrated" function integrated in the drive on the Motor
Module (MM) has detected an error in the sign–of–life of the safety
data between the Control Unit (CU) and MM and initiated a STOP A.
– There is either a DRIVE–CLiQ communications error or communica-
tions have failed.
– A time slice overflow of the safety software has occurred.
Fault value (r0949, decimal):
Only for internal Siemens troubleshooting.
Select safe standstill and then deselect again.
– Carry out a POWER ON (power off/on) for all components.
– Check whether there is a DRIVE–CLiQ communications error
between the Control Unit and the Motor Module involved and if
required, carry out a diagnostics routine for the faults identified.
– Deselect all drive functions that are not absolutely necessary.
– Reduce the number of drives.
– Check the electrical cabinet design and cable routing for EMC com-
pliance.

OFF2
IMMEDIATELY (POWER ON)
The "Safety Integrated" function integrated in the drive on the Motor
Module ((MM) has detected a brake control fault and initiated a STOP A.
– No motor holding brake connected.
– The motor holding brake control on the Motor Module or the Control
Unit is faulty.
– A DRIVE–CLiQ communications error has occurred between the
Control Unit and the Motor Module.
Fault value (r0949, decimal):
10: No brake connected or fault in the Motor Module brake control circuit
("open brake" operation).
30: Short–circuit in the brake winding or fault in the Motor Module brake
control circuit ("close brake" operation).
40: Defect in the brake control circuit of the Motor Module ("brake closed"
