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
Drive object: All objects
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.
See also: p7770 (NVRAM action)
Remedy: - Perform the remedy according to the results of the troubleshooting.
- If necessary, start the action again.
F03001 NVRAM checksum incorrect
Drive object: All objects
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 (power off/on) for all components.
F03500 (A) TM: Initialization
Drive object: CU_DCP, TM150, TM15DI_DO, TM31
Cause: When initializing the Terminal Modules, the terminals of the Control Unit or the Terminal Board 30, an internal
software error has occurred.
Fault value (r0949, interpret decimal):
yxxx dex
y = Only for internal Siemens troubleshooting
xxx = component number (p0151)
Remedy: - power down/power up the power supply for the Control Unit.
- check the DRIVE-CLiQ connection.
- if required, replace the Terminal Module.
The Terminal Module should be directly connected to a DRIVE-CLiQ socket of the Control Unit.
If the fault occurs again, replace the Terminal Module.
A03501 TM: Sampling time change
Drive object: CU_DCP, TM150, TM15DI_DO, TM31
Cause: The sampling times of the inputs/outputs were changed.
This change only becomes valid after the next boot.
Remedy: Carry out a POWER ON.
F03505 (N, A) TM: Analog input wire breakage
Drive object: TM15DI_DO, TM31
Cause: The wire-break monitoring for an analog input has responded.
The input current of the analog input has exceeded the threshold value parameterized in p4061[x].
Index x = 0: Analog input 0 (X521.1/X521.2)
Index x = 1: Analog input 1 (X521.3/X521.4)
