SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 06/2011

F01044 CU: Descriptive data error

Reaction: OFF2

Acknowledge: POWER ON

Cause: An error was detected when loading the descriptive data saved in the non-volatile memory.

Remedy: Replace the memory card or Control Unit.

A01045 Configuring data invalid

Reaction: NONE

Acknowledge: NONE

Cause: An error was detected when evaluating the parameter files PSxxxyyy.ACX, PTxxxyyy.ACX, CAxxxyyy.ACX, or

CCxxxyyy.ACX saved in the non-volatile memory.

Alarm value (r2124, interpret hexadecimal):

Only for internal Siemens troubleshooting.

Remedy: Restore the factory setting using (p0970 = 1) and re-load the project to the drive unit. Operation without any

restrictions is then possible.

After downloading the project, save the parameters in STARTER using "Copy RAM to ROM" or with p0971 = 1. This

overwrites the incorrect parameter files in the non-volatile memory.

A01049 It is not possible to write to file

Reaction: NONE

Acknowledge: NONE

Cause: It is not possible to write into a write-protected file (PSxxxxxx.acx). The write request was interrupted.

Alarm value (r2124, interpret decimal):

Drive object number.

Remedy: Check whether the "write protected" attribute has been set for the files in the non-volatile memory under

.../USER/SINAMICS/DATA/... When required, remove write protection and save again (e.g. set p0971 to 1).

A01064 (F) CU: Internal error (CRC)

Reaction: NONE

Acknowledge: NONE

Cause: CRC error in the Control Unit program memory

Remedy: - carry out a POWER ON (power off/on) for all components.

- upgrade firmware to later version.

- contact the Hotline.

A01066 Buffer memory: 70% fill level reached or exceeded

Reaction: NONE

Acknowledge: NONE

Cause: The non-volatile buffer memory for parameter changes is filled to at least 70%.

This can also occur if the buffer memory is active (p0014 = 1) and parameters are continually changed via a fieldbus

system.

Remedy: If required, de-activate and clear the buffer memory (p0014 = 0).

If required, clear the buffer memory (p0014 = 2).

In the following cases, the entries in the buffer memory are transferred into the ROM and then the buffer memory is

cleared:

- p0971 = 1

- power down/power up the Control Unit
