Spare part drive for a running line
The Siemens 6SL3210-1KE12-3UP1 is a SINAMICS G120C spare part drive rated at 0.75 kW with 150% overload for 3 seconds on 380-480V 3AC (+10/-20%), 47-63 Hz, unfiltered. It integrates PROFIBUS DP fieldbus and Safe Torque Off as standard, with an I/O interface of 6 digital inputs, 2 digital outputs, 1 analog input, and 1 analog output. The IP20 / UL Open Type protection suits panel-mount installations; the FSA form factor (196 x 73 x 203 mm) fits the standard G120C footprint.
The 0.75 kW rating at 150% overload for 3 seconds means it handles short-duration peak loads — useful for starting a small pump or conveyor motor without oversizing the drive. The 380-480V 3AC input range covers standard European and North American industrial supplies. PROFIBUS DP integration means it drops directly into a Siemens S7-300/400 or third-party PROFIBUS master network without an external gateway. Safe Torque Off (STO) is built in, so you can wire a safety relay directly to the drive terminals for emergency-stop circuits — no separate safety module needed. The IP20 / UL Open Type rating means it is designed for enclosure mounting, not washdown or outdoor use. The FSA size (196 x 73 x 203 mm) is the smallest G120C frame, so it fits tight panel layouts. External 24 V control supply is required.
Deployment context
This drive is sized for a 0.75 kW induction motor on a conveyor, fan, or pump in a control panel. The PROFIBUS DP interface connects to a PLC for speed reference and status monitoring. The integrated Safe Torque Off simplifies safety circuit wiring — wire a safety relay or light curtain to the STO terminals and the drive disables torque without a contactor.
