About the 6SL3120-1TE28-5AA3
About the 6SL3120-1TE28-5AA3
The Siemens 6SL3120-1TE28-5AA3 is a SINAMICS S120 Single Motor Module in the booksize frame, converting a 510-720 V DC link into a 3AC 400 V output rated at 85.0 A (IN), with a base-load current of 68.0 A and a peak of 141.0 A. It ships with a DRIVE-CLiQ cable, supports Extended Safety Integrated functions, and weighs 14.6 kg.
Selection Notes
This is the mid-current member of the booksize Single Motor Module range covered here, with an 85.0 A rated (IN) / 68.0 A base-load (IH) / 141.0 A peak (Imax) output, roughly triple the current of the smallest 30 A module and less than half of the 200 A module. Pick it for motors in the 37-46 kW class rather than running the smaller module continuously near its peak. Extended Safety Integrated support allows integrated safety functions (e.g. STO) without an external safety relay, and the 4.00 kHz pulse frequency with servo control up to 650 Hz output frequency suits dynamic servo axes.
Applications
Used as a single-axis power stage in SINAMICS S120 modular multi-axis drive systems — machine tools, printing and converting lines, and material-handling axes — sharing a DC link with an Active or Smart Line Module and other Motor Modules on the same bus.
