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 p0977 = 1 so that all of the parameter files are again completely written to the
non-volatile memory.
- replace the memory card or Control Unit.
Re byte 2 = 255:
- Correct the drive object type (see p0107).
F01039 (A) ACX: Writing to the parameter back-up file was unsuccessful
Drive object: All objects
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 = 070 --> FEPROM.BIN
a = 080 --> DEL4BOOT.TXT
a = 099 --> PROFIBUS parameter back-up file
b = xxx in the file names PSxxxyyy.***
b = 000 --> data save started with p0977 = 1 or p0971 = 1
b = 010 --> data save started with p0977 = 10
b = 011 --> data save started with p0977 = 11
b = 012 --> data save started with p0977 = 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
Drive object: All objects
Cause: A parameter was changed in the drive system which means that it is necessary to save the parameters and re-boot.
Remedy: - save parameters (p0971, p0977).
- carry out a POWER ON (power off/on) for all components.
Then:
- upload the drive unit (commissioning software).
F01041 Parameter save necessary
Drive object: All objects
Cause: Defective or missing files were detected on the memory card when booting.
Fault value (r0949, interpret decimal):
1: Source file cannot be opened.
2: Source file cannot be read.
3: Target directory cannot be set up.
4. Target file cannot be set up/opened.
5. Target file cannot be written to.
