4.2 List of faults and alarms
SINAMICS G130/G150
1384 List Manual (LH2), 07/2016, A5E03263479A
F01054 CU: System limit exceeded
Message value: %1
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: All objects
Component: Control Unit (CU) Propagation: GLOBAL
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: At least one system overload has been identified.
Fault value (r0949, interpret decimal):
1: Computing time load too high (r9976[1]).
5: Peak load too high (r9976[5]).
Note:
As long as this fault is present, it is not possible to save the parameters (p0971, p0977).
See also: r9976 (System utilization)
Remedy: For fault value = 1, 5:
- reduce the computing time load of the drive unit (r9976[1] and r9976[5]) to under 100 %.
- check the sampling times and adjust if necessary (p0115, p0799, p4099).
- deactivate function modules.
- deactivate drive objects.
- remove drive objects from the target topology.
- note the DRIVE-CLiQ topology rules and if required, change the DRIVE-CLiQ topology.
When using the Drive Control Chart (DCC) or free function blocks (FBLOCKS), the following applies:
- the computing time load of the individual run-time groups on a drive object can be read out in r21005 (DCC) or
r20005 (FBLOCKS).
- if necessary, the assignment of the run-time group (p21000, p20000) can be changed in order to increase the
sampling time (r21001, r20001).
- if necessary, reduce the number of cyclically calculated blocks (DCC) and/or function blocks (FBLOCKS).
F01055 CU: Internal error (SYNO of port and application not identical)
Message value: %1
Message class: Hardware/software error (1)
Drive object: B_INF, TM150, VECTOR_G
Component: Control Unit (CU) Propagation: DRIVE
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: All applications that operate with slaves at one port must be derived from the same SYNO clock cycle.
The first application whose registration (log-on) connects a slave to a port defines the SYNO clock cycle that will be
used as basis for the port.
Fault value (r0949, interpret hexadecimal):
Method ID.
Note:
Only for internal Siemens troubleshooting.
Remedy: Contact Technical Support.
F01056 CU: Internal error (clock cycle of parameter group already assigned differently)
Message value: %1
Message class: Hardware/software error (1)
Drive object: B_INF, TM150, VECTOR_G
Component: Control Unit (CU) Propagation: DRIVE
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The requested parameter group (IREG, NREG, ...) is already being used in a different clock cycle.
Fault value (r0949, interpret hexadecimal):
Method ID.
