The Siemens 6SL3210-1KE23-8UC1 is a SINAMICS G120C compact drive rated for 18.5 kW output with a 150% overload capability for 3 seconds — that extra headroom matters for starting a loaded conveyor or a pump that sees short-duration peak torque. It runs on a 380-480 VAC three-phase supply, 47-63 Hz, unfiltered. The IP20 / UL Open Type enclosure means it lives inside a panel, not on the wall.
I/O and fieldbus
Onboard I/O gives you 6 digital inputs, 2 digital outputs, 1 analog input, and 1 analog output — enough for basic speed reference and run/stop control without an add-on module. CANopen is integrated on the board, so no option card needed for that network. Safe Torque Off is built in as well, which keeps the safety circuit wiring clean: no separate safety relay if your machine category stops at STO.
Mechanical fit
It ships in Frame Size FSC — 295 x 140 x 203 mm (HxWxD). That footprint fits a standard 400 mm deep enclosure with room for a line reactor above or below. The external 24 V supply requirement means you'll need a separate 24 VDC power supply in the panel; the drive doesn't derive its control voltage from the DC bus.
