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

The Original New Siemens 6SL3120-2TE21-0AD0 SINAMICS S120 Double Motor Module is a high-performance dual-axis motor module designed for demanding multi-axis motion control applications in industrial automation systems. Part of the SINAMICS S120 modular drive system, this Booksize D-Type module converts a DC 600V input to dual 3AC 400V outputs at 9A per channel, enabling independent control of two synchronous or asynchronous motors in a compact footprint. Featuring internal air cooling, optimized pulse patterns, and support for extended Safety Integrated functions (SIL 2 / PL d), it delivers robust performance for high-dynamic motion control applications including machine tools, robotics, and packaging machinery.

Core Engineering Highlights:
DC 600V input (510–720V DC link) | 3AC 400V output | 2 x 9.0A rated output current | 2 x 4.8kW rated output power | Booksize D-Type form factor | Internal air cooling | Optimized pulse patterns | Extended Safety Integrated functions (SIL 2 / PL d) | DRIVE-CLiQ interface | IP20 protection | Up to 650 Hz output frequency (servo control)
