It accepts a 600 V DC input and delivers 400 V 3-phase AC at 5 A, with external air cooling. This is a spare part for existing S120 cabinet builds, not a standalone drive — it relies on a Smart Line Module or Active Line Module upstream for the DC link. The 5 A output current at 400 V 3AC sets the motor size this module can handle — roughly a 2.2 kW to 3 kW servo depending on duty cycle and peak current demand. The 600 V DC input means it connects directly to the S120 DC bus, not to a 400 V AC supply; the upstream line module handles the AC-to-DC conversion and regenerative braking. Booksize construction with external air cooling dictates the cabinet layout: the module needs clear airflow through its heatsink fins, so it cannot be sandwiched between two other modules without a cooling gap. The optimized pulse patterns and extended Safety Integrated functions (STO, SBC, SS1) are enabled via the Motor Module's firmware and the CU320-2 or CU310-2 control unit. If your application requires safe torque off without a separate contactor, this module supports it natively — but the safety function must be commissioned through STARTER or Startdrive, and the DRIVE-CLiQ cabling must be intact for the safety handshake.","metaTitle":"Siemens 6SL3121-1TE15-0AA3 SINAMICS S120 Single Motor Module","metaDescription":"Siemens 6SL3121-1TE15-0AA3 SINAMICS S120 Single Motor Module. 600 V DC input, 400 V 3AC output, 5 A.
