11.8 Configuring SIMATIC Drive Controller backup and restore
Backing up NVRAM data
p7775 = 1 stores the NVRAM data of the SINAMICS Integrated in the subdirectory
"SINAMICS.S7S\USER\SINAMICS\NVRAM\PMEMORY.ACX" on the memory card.
The storage operation backs up all data from the NVRAM.
Note
Backing up NVRAM data
NVRAM data backup to the memory card is also possible during pulse enable. If the drive is
moved during NVRAM data transfer, the data backup may not be consistent with the
NVRAM data.
Restoring NVRAM data
There are two situations that require NVRAM data to be restored.
● Replacement of the SIMATIC Drive Controller.
● Targeted NVRAM data restore due to suspected data errors.
Replacement of the SIMATIC Drive Controller:
The SINAMICS Integrated detects a replacement based on the serial number of the
SIMATIC Drive Controller. Following POWER ON, the NVRAM of the SINAMICS Integrated
is cleared and the NVRAM data is then loaded from the SIMATIC memory card.
NVRAM restore:
A targeted restore process of the saved NVRAM data is triggered by setting p7775 = 2. The
original file is first deleted in NVRAM. If the file "PMEMORY.ACX" is available and has a
valid checksum, it is loaded to the NVRAM.
The following data is not restored:
● Operating hours counter
● Temperature
● Safety logbook
● Crash diagnostics data
Deleting NVRAM data
p7775 = 3 deletes the NVRAM data.
The following data is not deleted in the process:
● Operating hours counter
● Temperature
● Safety logbook
● Crash diagnostics data
