4 Faults and alarms
4.2 List of faults and alarms
A01045 CU: Configuring data invalid
Message value: %1
Message class: Hardware / software error (1)
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: An error was detected when evaluating the parameter files PSxxxyyy.ACX, PTxxxyyy.ACX, CAxxxyyy.ACX, or
CCxxxyyy.ACX saved in the non-volatile memory. Because of this, under certain circumstances, several of the saved
parameter values were not able to be accepted. Also see r9406 up to r9408.
Alarm value (r2124, interpret hexadecimal):
Only for internal Siemens troubleshooting.
Remedy: - Check the parameters displayed in r9406 up to r9408, and correct these if required.
- Restore the factory setting using (p0976 = 1) and re-load the project into the drive unit.
Then save the parameterization in STARTER using the "Copy RAM to ROM" function or with p0977 = 1. This
overwrites the incorrect parameter files in the non-volatile memory – and the alarm is withdrawn.
A01049 CU: It is not possible to write to file
Message value: %1
Message class: Hardware / software error (1)
Drive object: All objects
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 p0977 to 1).
F01050 Memory card and device incompatible
Message value: -
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: All objects
Reaction: Vector: OFF2 (NONE, OFF1, OFF3)
Infeed: OFF2 (NONE, OFF1)
Acknowledge: IMMEDIATELY
Cause: The memory card and the device type do not match (e.g. a memory card for SINAMICS S is inserted in SINAMICS
G).
Remedy: - insert the matching memory card.
- use the matching Control Unit or power unit.
F01054 CU: System limit exceeded
Message value: %1
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: All objects
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).
