03/2009
Cause: An error occurred when loading PSxxxyyy.ACX or PTxxxyyy.ACX files from the CompactFlash card
or from the volatile memory of the Control Unit.
Fault value (r0949, interpret hexadecimal):
Byte 1: yyy in the file name PSxxxyyy.ACX
yyy = 000 --> consistency back-up file
yyy = 001 ... 062 --> drive object number
yyy = 099 --> PROFIBUS parameter back-up file
Byte 4, 3, 2:
Only for internal Siemens troubleshooting.
Remedy: - If you have saved the project data using the commissioning software, carry out a new download for
your project. Save using the function "Copy RAM to ROM" or with p0977 = 1 so that all of the param-
eter files are again completely written to the CompactFlash card.
- replace the CompactFlash card.
201039 <location>ACX: Writing to the parameter back-up file was unsuccessful
Message %1
value:
Drive object: All objects
Reaction: A_INFEED: NONE (OFF2)
SERVO: NONE (OFF1, OFF2, OFF3)
VECTOR: NONE (OFF1, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: Writing to at least one parameter back-up file PSxxxyyy.*** on the CompactFlash card was unsuc-
cessful.
- on the CompactFlash card 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 on the CompactFlash card.
- the CompactFlash card 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 p0977 = 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 on the CompactFlash card. Approx. 40 kbyte of free memory space is
required for every drive object in the system.
- replace the CompactFlash card.
201040 <location>Save parameter settings and carry out a POWER ON
Message -
value:
Drive object: All objects
Reaction: OFF2
Acknowledge: POWER ON
Cause: A parameter was changed in the drive system which means that it is necessary to save the parameters
and re-boot (e.g. p0110).
Remedy: - save the parameters (p0971/p0977).
- carry out a POWER ON (power off/on) for all components.
