4 Faults and alarms
4.2 List of faults and alarms
Remedy:
- check the parameters displayed in r9406 up to r9408, and correct these if required.
- Restore the factory setting using (p0970 = 1) and re-load the project into the drive unit.
Then save the parameterization in STARTER using the function "Copy RAM to ROM" or with p0971 = 1. This
overwrites the incorrect parameter files in the non-volatile memory – and the alarm is withdrawn.

transferred), r9408 (PS file fault code parameter not transferred)
A01049
It is not possible to write to file
Message class:
Hardware/software error (1)
Reaction:
NONE
Acknowledge:
NONE
Cause:
It is not possible to write into a write-protected file (PSxxxxxx.acx). The write request was interrupted.
Alarm value (r2124, interpret decimal):
Drive object number.
Remedy:
Check whether the "write protected" attribute has been set for the files in the non-volatile memory under
.../USER/SINAMICS/DATA/... When required, remove write protection and save again (e.g. set p0971 to 1).
F01054
CU: System limit exceeded
Message class:
Error in the parameterization / configuration / commissioning procedure (18)
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).
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).
- de-activate function modules.
- de-activate 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).
A01064 (F)
CU: Internal error (CRC)
Message class:
Hardware/software error (1)
Reaction:
NONE
Acknowledge:
NONE
Cause:
A checksum error (CRC error) has occurred in the Control Unit program memory
Remedy:
- carry out a POWER ON (switch-off/switch-on) for all components.
- upgrade firmware to later version.
- contact Technical Support.
