Backing up / restoring / deleting SINAMICS NVRAM data

Requirement
SIMOTION D410-2 as of SIMOTION V4.3
SINAMICS S120 CU310-2/CU320-2 as of SINAMICS V4.5
For other supported SINAMICS Control Units, refer to the SINAMICS manuals.
Saving the NVRAM data
The backup of the SINAMICS NVRAM data is performed by setting parameter p7775 to 1.
Where:
● Parameter p7775 can also be set to 1 during pulse enable.
● A warm restart is not required.
Note
The consistent backup of the NVRAM data must be ensured by the application.
Make sure that there is no change of the NVRAM contents during the data backup. The greatest
possible consistency is achieved when
● Backup is performed during pulse disable or
● The drives are run down to 0 Hz.
The data for the S120 Control Units and the SINAMICS Integrated is stored in the backup file
"PMEMORY.ACX" in the folder " ... \USER\SINAMICS\NVRAM" on the CompactFlash card.
For the S120 Control Units, the data is stored on the CompactFlash card of the S120 Control
Unit.
Similar to the non-volatile SIMOTION data, an already existing PMEMORY.ACX file is first
renamed as PMEMORY.BAK and then the PMEMORY.ACX file is generated when you save
the SINAMICS data.
If an error occurs during backup, the BAK file can be used to restore the data.
Parameter p7775 is set to 0 at the end of the backup.
