820 List Manual (LH11), 01/2016, A5E33839529
F02152 (A) OA: Insufficient memory
Message class: Hardware/software error (1)
Reaction: OFF1
Acknowledge: IMMEDIATELY (POWER ON)
Cause: Too many functions have been configured on this Control Unit (e.g. too many drives, function modules, data sets, OA
applications, blocks, etc).
Fault value (r0949, interpret decimal):
Only for internal Siemens troubleshooting.
Remedy: - change the configuration on this Control Unit (e.g. fewer drives, function modules, data sets, OA applications,
blocks, etc).
- use an additional Control Unit.
Note:
OA: Open Architecture
F03000 NVRAM fault on action
Message class: Hardware/software error (1)
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: A fault occurred during execution of action p7770 = 1 or 2 for the NVRAM data.
Fault value (r0949, interpret hexadecimal):
yyxx hex: yy = fault cause, xx = application ID
yy = 1:
The action p7770 = 1 is not supported by this version if Drive Control Chart (DCC) is activated for the drive object
concerned.
yy = 2:
The data length of the specified application is not the same in the NVRAM and the backup.
yy = 3:
The data checksum in p7774 is not correct.
yy = 4:
No data available to load.
Remedy: - Perform the remedy according to the results of the troubleshooting.
- if necessary, start the action again.
F03001 NVRAM checksum incorrect
Message class: Hardware/software error (1)
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: A checksum error occurred when evaluating the non-volatile data (NVRAM) on the Control Unit.
The NVRAM data affected was deleted.
Remedy: Carry out a POWER ON (switch-off/switch-on) for all components.
F03505 (N, A) Analog input wire breakage
Message class: External measured value / signal state outside the permissible range (16)
Reaction: OFF1 (NONE, OFF2)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The wire-break monitoring for an analog input has responded.
The input value of the analog input has undershot the threshold value parameterized in p0761[0...3].
p0756[0]: analog input 0 (only CU240D-2)
p0756[1]: analog input 1 (only CU240D-2)
Fault value (r0949, interpret decimal):
yxxx dec
y = analog input (0 = analog input 0 (AI 0), 1 = analog input 1 (AI 1))
xxx = component number (p0151)
