Siemens 6SL3120-1TE21-8AD0 SINAMICS S120 Single Motor Module 18A 9.7kW D-Type Drive Module

The Siemens SINAMICS S120 Single Motor Module (6SL3120-1TE21-8AD0) is a D-type booksize power module that converts a 510...720 V DC link into a 400 V 3 AC output rated for 18.0 A (IH 15.3 A, Imax 54.0 A), delivering 9.7 kW based on rated current. It includes a DRIVE-CLiQ cable and supports the extended Safety Integrated functions at a 4.00 kHz pulse frequency.

Technical Specifications

Selection Notes

At 18.0 A rated / 54.0 A peak, this sits in the middle of this D-type Single Motor Module range - it shares the same 510-720 V DC link window as the lower- and higher-current versions but adds headroom for motors whose base load current exceeds roughly 9 A. The 220 µF DC-link capacitance and 100 A busbar rating are matched to this current class; check the busbar's total current budget before combining it with a higher-power line module or additional motor modules on the same DC link.

Applications

Drives a single servo or induction motor axis from a SINAMICS S120 DC link in machine tools, packaging, and material-handling equipment, using the extended Safety Integrated functions built into this module for integrated safe torque off and safe motion.
