The Siemens 6SL3210-1KE23-8UC0 is a SINAMICS G120C variable frequency drive rated for 18.5 kW output with a 150% overload capability for 3 seconds — enough headroom to start a loaded conveyor or pump without oversizing the drive. It runs on 380-480 VAC three-phase, 47-63 Hz, unfiltered, so it expects a clean mains or an external line reactor if the supply is noisy. The IP20 / UL Open Type enclosure means it lives inside a panel, not on the wall.
I/O and Safety
The I/O interface gives you 6 digital inputs, 2 digital outputs, 1 analog input, and 1 analog output — enough for basic speed setpoint, run/stop, and a fault relay without an add-on module. Safe Torque Off is integrated on the drive, so you can wire a safety relay or light curtain directly to the STO terminals and skip an external contactor for the safety circuit.
