Siemens 6SN1123-1AA00-0DA2 Power Module

Siemens 6SN1123-1AA00-0DA2 Power Module is the SIMODRIVE 611 one‑axis drive power unit rated for 80 A with internal cooling, designed to power a single servo axis in Siemens’ legacy SIMODRIVE 611 systems. The module places the motor terminals A1 and A2 on the power module itself, delivering a compact power stage for Axis 1. Verified motor current ratings specify 28 A for the feed motor and 30 A for the main spindle motor, aligning with typical 1FT5/1FT6 servo motors within the SIMODRIVE 611 family. With internal cooling, the unit is built for continuous operation in industrial panels where heat management is essential. Weighing approximately 8.3 kg, the 6SN1123-1AA00-0DA2 is a robust power module suitable for legacy installations that require an 80 A variant of the 6SN1123-1AA00 family. This power module is commonly referenced as a spare part and is used to replace earlier 6SN1123-1AA00-0DA1 variants in SIMODRIVE 611 configurations, with documentation in the SIMODRIVE 611 Configuration Manual (PJU) confirming its role within Axis 1 power delivery. Designed for Siemens automation ecosystems, this module supports the 611 drive converters’ architecture and is compatible with the 80 A power‑section standard of its lineage, making it a precise fit for customers maintaining or upgrading aging SIMODRIVE 611 installations.
