Drive selection memo
The Siemens 6SL3210-1KE23-2AC0 is a SINAMICS G120C compact drive rated for 15.0 kW output power on a 380-480 V 3AC supply, with a 150% overload capability for 3 seconds — sized for a 15 kW 4-pole induction motor driving a pump or conveyor on 400 V three-phase. The integrated Class A EMC filter covers conducted emissions for most industrial environments without an external filter. Safe Torque Off (STO) is onboard, so the drive can be wired into a safety circuit that removes torque at the shaft without a separate safety relay.
I/O and fieldbus
The onboard I/O interface gives you 6 digital inputs, 2 digital outputs, 1 analog input, and 1 analog output — enough for basic speed reference and run/stop control from a PLC or local panel. CANopen is integrated as the fieldbus interface; no optional communication module is required for CANopen networks. The IP20 / UL Open Type rating means it mounts inside a panel or cabinet; the 295 x 140 x 203 mm FSC footprint fits the standard G120C frame size C.
