Siemens 6AU1400-2QA20-0AA0 SIMOTION D 2GB CF Card for D4x5-2 Memory Card

The Siemens 6AU1400-2QA20-0AA0 is a 2 GB Compact Flash card for SIMOTION D4x5-2 drive-based controllers, preloaded with the SINAMICS drive software V5.x and the matching SIMOTION kernel at the current software version. It is not compatible with the SIMOTION D410, D4x5, or D410-2 controller variants, so the exact controller generation must be confirmed before ordering it as a spare or replacement part.

Technical Specifications

Selection Notes

The D4x5-2 compatibility note is the detail that matters when ordering: this 2 GB card is built for the second-generation D4x5-2 controllers and is explicitly ruled out for the original D410, D4x5, and D410-2 models, so confirm the controller generation before ordering a replacement or spare card. Siemens lists it as compatible alongside the smaller-capacity 1 GB CF card 6AU1400-2PA23-0AA0 for the same controller family, so capacity choice comes down to project size and firmware/data storage headroom rather than compatibility.
