Siemens 6SN1123-1AA00-0LA1 Programmable Logic Controller Module

Siemens 6SN1123-1AA00-0LA1 is a SIMODRIVE 611 power module — the single‑axis power stage used in Siemens’ SIMODRIVE 611 servo drive systems for CNC and industrial automation. As part of the SIMODRIVE 611 family, this module provides the high‑power electronics that drive one servo motor axis. The MLFB designation 6SN1123-1AA00-0LA1 lists continuous motor current options of 45 A, 60 A, and 76 A, depending on configuration, with the specific rating selected to match the connected servo motor and load. Typical applications include precise servo control in CNC machines and other equipment that requires reliable, axis‑level drive power within a compact module.
