Siemens 6SL3120-2TE21-0AD0 SINAMICS S120 Double Motor Module 2x9A Booksize

The Siemens 6SL3120-2TE21-0AD0 is a SINAMICS S120 double motor module in Booksize D-type format, converting a 510-720 V DC link to two independent 3-phase 400 V outputs rated 9.0 A each, for driving two motors from a single shared infeed. It includes an integrated DRIVE-CLiQ cable and supports the Extended Safety Integrated functions.

Selection Notes

The double-axis layout is the reason to choose this module over a single motor module: two 9 A outputs share one DC-link connection and one DRIVE-CLiQ topology slot, which cuts Book Size rack width on machines with two similarly sized axes. The Extended Safety Integrated support lets both axes implement STO/SS1-type safety functions without an external safety relay. Because Imax is limited to 27 A per axis against a 9 A rated current, this module suits intermittent-duty axes rather than continuous full-load running near the overload ceiling.

Applications

Drives two coordinated low-power axes, such as gantry or pick-and-place servo pairs, from a single SINAMICS S120 Booksize line module in machine tool and packaging applications.
