The Siemens 6SL3210-1KE12-3UB0 is a SINAMICS G120C compact drive rated for 0.75 kW output power with a 150% overload capability for 3 seconds, making it suitable for short-duration peak torque demands on pumps, fans, or conveyors. It runs on a 3-phase 380-480 VAC supply at 47-63 Hz and is unfiltered, so plan for external EMC filtering if the installation requires it. The I/O interface includes 6 digital inputs, 2 digital outputs, 1 analog input, and 1 analog output — enough for basic speed control and feedback without an expansion module. Safe Torque Off (STO) is integrated, which simplifies safety circuit wiring for applications needing a controlled stop.
The integrated fieldbus is USS / Modbus RTU, so it drops into existing Modbus RTU networks without a gateway. If your line uses PROFINET or EtherNet/IP, you will need a communication module — the G120C family supports those via optional cards, but this base variant does not include them.
