4 Faults and alarms
4.2 List of faults and alarms
Additional values:
Only for internal Siemens troubleshooting.
Byte 4, 3:
Only for internal Siemens troubleshooting.
Remedy: - if you have saved the project data using the commissioning software, download the project again. Save using the
function "Copy RAM to ROM" or with p0971 = 1. This means that the parameter files are again completely written to
the non-volatile memory.
- replace the memory card or Control Unit.
F01039 (A) ACX: Writing to the parameter back-up file was unsuccessful
Message class: Hardware/software error (1)
Reaction: NONE (OFF1, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: Writing to at least one parameter back-up file PSxxxyyy.*** in the non-volatile memory was unsuccessful.
- in the directory /USER/SINAMICS/DATA/ at least one parameter back-up file PSxxxyyy.*** has the "read only" file
attribute and cannot be overwritten.
- there is not sufficient free memory space available.
- the non-volatile memory is defective and cannot be written to.
Fault value (r0949, interpret hexadecimal):
dcba hex
a = yyy in the file names PSxxxyyy.***
a = 000 --> consistency back-up file
a = 001 ... 062 --> drive object number
a = 099 --> PROFIBUS parameter back-up file
b = xxx in the file names PSxxxyyy.***
b = 000 --> data save started with p0971 = 1
b = 010 --> data save started with p0971 = 10
b = 011 --> data save started with p0971 = 11
b = 012 --> data save started with p0971 = 12
d, c:
Only for internal Siemens troubleshooting.
Remedy: - check the file attribute of the files (PSxxxyyy.***, CAxxxyyy.***, CCxxxyyy.***) and, if required, change from "read
only" to "writeable".
- check the free memory space in the non-volatile memory. Approx. 80 kbyte of free memory space is required for
every drive object in the system.
- replace the memory card or Control Unit.
F01040 Save parameter settings and carry out a POWER ON
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: OFF2
Acknowledge: POWER ON
Cause: A parameter has been changed that requires the parameters to be backed up and the Control Unit to be switched
OFF and ON again.
Remedy: - Save parameters (p0971).
- carry out a POWER ON (switch-off/switch-on) for the Control Unit.
F01042 Parameter error during project download
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: OFF2 (NONE, OFF1, OFF3)
Acknowledge: IMMEDIATELY
Cause: An error was detected when downloading a project using the commissioning software (e.g. incorrect parameter
value).
For the specified parameter, it was detected that dynamic limits were exceeded that may possibly depend on other
parameters.
