Drive selection memo
The Siemens 6SL3210-1KE15-8UC0 is a SINAMICS G120C compact drive rated for 2.2 kW output with a 150% overload capability for 3 seconds — enough headroom to handle short-duration load spikes on a conveyor or pump start. It runs on a 380-480 VAC three-phase supply, 47-63 Hz, unfiltered. The integrated CANopen fieldbus and Safe Torque Off (STO) mean this unit can drop into a CAN-based line without an extra option card, and the STO satisfies SIL 3 / PL e safety requirements for guarding zones without an external safety relay.
I/O and integration
The onboard I/O interface provides 6 digital inputs, 2 digital outputs, 1 analog input, and 1 analog output — enough for basic speed reference and run/stop control without an additional I/O module. The IP20 / UL Open Type enclosure is suited for a clean, dry cabinet; mount it on the DIN rail or backplate in the standard FSA footprint (196 x 73 x 203 mm HxWxD).
