Backing Up / Restoring / Deleting Sinamics Nvram Data - Siemens SIMOTION D4 5-2 Series Commissioning And Hardware Installation Manual

6.5.4

Backing up / restoring / deleting SINAMICS NVRAM data

Requirement
● SIMOTION D: SIMOTION D4xx-2/CX32-2 as of SIMOTION V4.3 / SINAMICS V4.5
● SINAMICS S120 CU310-2/CU320-2: SINAMICS V4.5
● Other supported SINAMICS CUs: See the SINAMICS manuals
Saving the NVRAM data
The backup of the SINAMICS NVRAM data is performed by setting parameter p7775 to 1.
The following applies:
● 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 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 is stored on the CompactFlash card:
● "....\USER\SINAMICS\NVRAM" for S120 CUs and SINAMICS Integrated
● "....\USER\SINAMICS\\NVRAM\xx" for CX32-2 (xx corresponds to the DRIVE-CLiQ port)
The data itself is stored in the PMEMORY.ACX backup file.
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.
