DRIVE-CLiQ cable.","salesMarkdown":"The Siemens 6SL3120-1TE21-0AA4 is a SINAMICS S120 Single Motor Module designated as a spare part — it's the motor-side inverter stage in a booksize drive system, taking 600 V DC from the shared DC link and outputting 400 V three-phase AC at 9 A to one servo or induction motor. Rated for 9 A output, this module pairs with a motor roughly in the 3–4 kW range on 400 VAC, depending on duty cycle and thermal load. The booksize format stacks tightly on the mounting rail alongside the line module and control unit, so plan your cabinet fill factor around the 50 mm width typical for this frame. For BOM planning: this is an active, orderable spare part, not a phase-out. No immediate LTB window is in effect. ## Integration notes for the field Internal air cooling means the module relies on the cabinet's ambient airflow — no external fan or coolant loop. Keep the surrounding free space per Siemens mounting guidelines to avoid derating. The DRIVE-CLiQ cable is included, so you only need to run the motor power cable and DC-link busbars. Optimized pulse patterns reduce motor losses and audible noise at higher switching frequencies. Extended Safety Integrated functions (STO, SS1, SBC, etc.) are supported without an external safety relay — wiring goes through the safe torque-off terminals on the Control Unit, not this module directly.","metaTitle":"Siemens 6SL3120-1TE21-0AA4 SINAMICS S120 Single Motor Module","metaDescription":"Siemens 6SL3120-1TE21-0AA4 SINAMICS S120 Single Motor Module, 600V DC input, 400V 3AC output, 9A, booksize.
