Siemens 6SN1123-1AA00-0KA1 Simodrive 611 Power Module

The Siemens 6SN1123-1AA00-0KA1 SIMODRIVE 611 Power Module is a high-current, single-axis power converter designed to supply a servo motor from Siemens' SIMODRIVE 611 drive family; the unit is rated for 400 A on the axis and includes dedicated motor terminals A1 and A2 at the power module for direct motor connections. Configured with internal cooling, this module relies on an external cooling solution—such as an add-on fan or cooling unit—to safely dissipate heat under typical operating loads encountered in industrial automation environments. As a spare part in the SIMODRIVE 611 lineup, it supports one axis of motion with robust, compact power electronics that integrate with the drive's control and protection features. In practice, it is used in automation and manufacturing applications where a single servo axis requires reliable, high-current drive performance, and it adheres to Siemens' part-numbering scheme 6SN1123-1AA00-0KA1 for tracing and compatibility within the SIMODRIVE 611 ecosystem. It is intended as a spare part for service and maintenance workflows, supporting quick replacement within existing SIMODRIVE 611 installations.
