Drive selection memo — 15 kW SINAMICS G120C
The Siemens 6SL3210-1KE23-2AB0 is a SINAMICS G120C variable frequency drive rated at 15.0 kW output with a 150% overload capability for 3 seconds — enough headroom to start a loaded conveyor or pump across the 380-480 V 3AC range without oversizing the frame. Input frequency covers 47-63 Hz, and the integrated Class A EMC filter means it meets conducted emission limits for most industrial environments without an external add-on — saves a DIN-rail slot and a wiring step. The I/O complement — 6 digital inputs, 2 digital outputs, 1 analog input, 1 analog output — handles basic machine control and feedback without an expansion module. Safe Torque-Off is integrated, so you can wire the safety circuit directly to the drive and skip an external safety relay for the stop function. Fieldbus is USS/MODBUS RTU onboard; no option card needed for those protocols. The IP20 / UL Open Type enclosure (FSC, 295 x 140 x 203 mm) is sized for a standard cabinet.
