Siemens 6SN1123-1AA01-0FA0 LT Module Interface

Siemens 6SN1123-1AA01-0FA0 LT Module Interface is the internal-cooled LT module designed for the SIMODRIVE 611 digital servo drive family. Identified as LT-MODUL INT, it carries a 200 A rating and serves as the power interface between the drive’s main power module and the motor connections, benefiting from Siemens’ integrated cooling within the drive rack. As part of the SIMODRIVE 611U system, this LT module works alongside other modules in the rack to deliver precise torque and speed control for servo motors used in automated equipment. The 6SN1123-1AA01-0FA0 designation is documented in Siemens literature for the SIMODRIVE 611 family and is commonly referenced in spare-parts catalogs and retrofit listings for legacy Siemens drive installations. Installation and maintenance should be performed by qualified personnel familiar with SIMODRIVE hardware to ensure proper thermal management and reliable operation in industrial environments.
