The Siemens 6SL3254-0BM00-0AA0 is a first-generation SINAMICS G MMC (Memory Card) carrying 32 MB of parameter memory, designed as a spare part for the CU240E, CU240S, CU240D control units and for the ET 200S FC and ET 200pro FC drive interfaces. It stores drive parameters, firmware, and application data for SINAMICS G-series converters in a compact, plug-in format.
This part is classified at a mature lifecycle stage, meaning it is no longer in active volume production but remains available through independent distribution channels. For a BOM line that depends on this exact memory card, sourcing is via RFQ — availability and current pricing are confirmed at quote time. No official Siemens successor order code is listed for this first-generation MMC; if a replacement is needed, the integrator should verify compatibility with the specific CU240 variant in the field.
The 32 MB capacity is sufficient for parameter sets and firmware for single-axis SINAMICS G applications. It is not cross-compatible with the SINAMICS S-series or later G120 control units that use a different memory card format. The part number on the label reads 6SL3-254-0BM00-0AA0.
