4 Faults and alarms
4.2 List of faults and alarms
SINAMICS G120 Control Units CU240B-2/CU240E-2
796 List Manual (LH11), 01/2016, A5E33839529
Remedy: - save all parameters (p0977 = 1 or p0971 = 1 or "copy RAM to ROM").
- acknowledge fault (e.g. BI: p2103).

F01649 SI P1 (CU): Internal software error
Message class: Hardware/software error (1)
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: An internal error in the Safety Integrated software on processor 1 has occurred.
Note:
This fault results in a STOP A that cannot be acknowledged.
Fault value (r0949, interpret hexadecimal):
Only for internal Siemens troubleshooting.
Remedy: - carry out a POWER ON (switch-off/switch-on).
- re-commission the "Safety Integrated" function and carry out a POWER ON.
- contact Technical Support.
- replace Control Unit.
F01650 SI P1 (CU): Acceptance test required
Message class: Safety monitoring channel has identified an error (10)
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The drive-integrated "Safety Integrated" function on processor 1 requires an acceptance test.
Note:
This fault results in a STOP A that can be acknowledged.
Fault value (r0949, interpret decimal):
130: Safety parameters for processor 2 not available.
Note:
This fault value is always output when Safety Integrated is commissioned for the first time.
1000: Reference and actual checksum on processor 1 are not identical (booting).
- at least one checksum-checked piece of data is defective.
- safety parameters set offline and loaded into the Control Unit.
2000: Reference and actual checksum on processor 1 are not identical (commissioning mode).
- reference checksum incorrectly entered on processor 1 (p9799 not equal to r9798).
- when de-activating the safety functions, p9501 was not deleted.
2001: Reference and actual checksum on processor 2 are not identical (commissioning mode).
- reference checksum incorrectly entered on processor 2 (p9899 not equal to r9898).
- when de-activating the safety functions, p9501 was not deleted.
2002: Enable of safety-related functions between the processor 1 and processor 2 differ (p9601 not equal to p9801).
2003: Acceptance test is required as a safety parameter has been changed.
2004: An acceptance test is required because a project with enabled safety-functions has been downloaded.
2005: The Safety logbook has identified that a functional safety checksum has changed. An acceptance test is
required.
2010: Enable of safety-related brake control between the two monitoring channels differ (p9602 not equal to p9802).
2020: Error when saving the safety parameters for the processor 2.
9999: Subsequent response of another safety-related fault that occurred when booting that requires an acceptance
test.
Remedy: For fault value = 130:
- carry out safety commissioning routine.
For fault value = 1000:
- again carry out safety commissioning routine.
- replace the memory card or Control Unit.
- Using STARTER, activate the safety parameters for the drive involved (change settings, copy parameters, activate
settings).
For fault value = 2000:
- check the safety parameters on processor 1 and adapt the reference checksum (p9799).
