DRIVE-CLiQ cable.","salesMarkdown":"The Siemens 6SL3120-1TE21-8AA3 is a SINAMICS S120 Single Motor Module designated as a spare part, meaning it is intended for replacement in existing S120 drives rather than new system builds. It accepts a 600 V DC input and delivers 400 V three-phase AC output at 18 A, in the booksize form factor with internal air cooling. The module supports optimized pulse patterns and includes extended Safety Integrated functions, with a DRIVE-CLiQ cable for communication. The 18 A rating governs motor current for a single axis — sized for a 3-phase induction motor in that current class, typical for small conveyors, spindle drives, or feed axes in machine tools. ## Integration Notes The booksize format mounts in the SINAMICS S120 cabinet lineup. Internal air cooling draws cooling air through the module — verify clearance above and below for the airflow path. The 600 V DC input comes from the S120 DC link, fed by the line module. The 400 V three-phase output at 18 A drives a single motor; the extended Safety Integrated functions (STO, SS1, SBC) are enabled via the control unit and require a safety-rated controller or F-CPU. Optimized pulse patterns reduce motor losses and audible noise at low speeds — relevant for precision feed axes.","metaTitle":"Siemens 6SL3120-1TE21-8AA3 SINAMICS S120 Single Motor Module","metaDescription":"Siemens SINAMICS S120 Single Motor Module 6SL3120-1TE21-8AA3, 600 V DC input, 400 V 3 AC output, 18 A, booksize.
