The Siemens 6SL3210-1KE14-3UB0 is a SINAMICS G120C compact drive rated for 1.5 kW output with a 150% overload capability for 3 seconds — enough headroom to handle short-duration load spikes on a conveyor or pump start without oversizing the drive. It accepts 380-480 VAC three-phase input at 47-63 Hz and comes unfiltered, so plan for an external line filter if the installation must meet conducted emission limits for the residential or light-industrial mains.
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 control, run/stop, and fault feedback without an expansion module. Fieldbus is integrated as USS or MODBUS RTU on the same physical port; set the protocol via parameter before commissioning. If the line uses PROFINET or EtherNet/IP, you will need a separate communication module.
Safety and integration
Safe-Torque-Off (STO) is integrated, so the drive can be wired into a safety circuit that removes torque without disconnecting the mains — standard for guarding applications. The FSA frame measures 196 x 73 x 203 mm (HxWxD) and carries an IP20 / UL Open Type rating, meaning it is intended for installation inside a clean, dry enclosure, not for washdown or outdoor placement. Mount it on a DIN rail or backplate with adequate clearance above and below for airflow.
