<location>SI CU: Sign-of-life error in safety data
Reaction:
OFF2
Acknowledge:
IMMEDIATELY (POWER ON)
Cause:
The drive-based "Safety Integrated" function in the control unit (CU) has detected an error
in the sign-of-life of the safety data between the CU and motor module (MM) and initiated
a STOP A.
- there is either a DRIVE-CLIQ communications error or communications have failed.
- a time slice overflow of the safety software has occurred.
Note:
This fault results in the following safety stop response dependent on p9501:
- Motion monitoring not enabled (p9501 = 0) --> STOP A that can be acknowledged.
- Motion monitoring not enabled (p9501 = 0) --> STOP A that cannot be acknowledged
(POWER ON).
Fault value (r0949, decimal):
Only for internal Siemens troubleshooting.
Remedy:
Motion monitoring not enabled (p9501 = 0):
- select safe standstill and then de-select again.
Motion monitoring enabled (p9501 > 0):
- carry-out a POWER ON.
Independent of the motion monitoring enable:
- 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.
- de-select all drive functions that are not absolutely necessary.
- reduce the number of drives.
- check the electrical cabinet design and cable routing for EMC compliance
