Siemens 6SN1123-1AA00-0EA INT Module Simodrive LT

Siemens 6SN1123-1AA00-0EA INT Module Simodrive LT is the LT-Modul power stage for a single-axis SIMODRIVE 611 drive, designed to deliver robust servo performance in automation and CNC environments. The INT.160A variant provides 160 A of continuous current for axis 1 and uses internal cooling to manage thermal load in demanding motor applications. This digital power module operates within a SIMODRIVE 611 digital drive system, serving as the primary power path for axis 1 motors and forming part of Siemens’ legacy LT-series components. Siemens documentation lists axis-1 current ratings including 1FT5 up to 80 A, 1FT6 up to 56 A, and 1PH and asynchronous currents near 60 A, information vital for motor selection and drive tuning. Availability notes from Siemens Industry Mall indicate this part is a spare in the SIMODRIVE 611 ecosystem and is listed as no longer available, reflecting its status in older installations while still compatible with retrofits or repairs where applicable. Suitable for machine tools, robotics, and automation lines that rely on the SIMODRIVE 611 architecture, this 6SN1123-1AA00-0EA INT LT module enables reliable, high-current axis 1 control when paired with an appropriate 611 servo amplifier and motor set.
