The Siemens 6SL30543EH001BA0 is a memory and storage module from the SINAMICS G130 drive family, classified under Computer Accessories in the Data Communications category. This is the component that holds the firmware and parameter sets for the drive controller — if you're rebuilding a G130 cabinet or swapping a CU, this is the part that carries the configuration.
What the Category Tells You
Classified under Computer Accessories > Memory & Storage, this module is the non-volatile memory card or CFast card that stores the SINAMICS G130 firmware, parameters, and language packs. It plugs into the Control Unit slot and is what makes the drive boot with your specific application profile. If you're sourcing a replacement, match the firmware version on the existing card — the hardware order code alone doesn't guarantee identical parameter content.
