6SL3210-1KE31-1UF1 SINAMICS G120C Compact Inverter

The 6SL3210‑1KE31‑1UF1 is an all‑in‑one compact drive of Siemens SINAMICS G120C series. It integrates power unit, control board and I/O terminals into a single unit, designed to regulate speed and torque for 3‑phase asynchronous motors with rated power 55kW. Built‑in RS485 USS / Modbus RTU communication interface, it can connect with PLC, HMI and upper‑level automation systems for remote monitoring and parameter adjustment. Featuring sensorless vector control, outstanding overload capacity and comprehensive protection functions, this compact frequency converter is suitable for fan, pump, conveyor and general‑purpose machinery, supporting quick commissioning for medium‑high power automation projects.

• All‑in‑one Compact Integrated Design Power module and control unit integrated as one piece, no extra control unit required, saves cabinet installation space and reduces wiring workload.
• RS485 USS & Modbus RTU On‑board Interface Standard RS485 port, supports USS and Modbus‑RTU protocols, convenient for multi‑inverter networking and centralized group control.
• Powerful Sensorless Vector Control Stable torque output at low speed, supports V/F and SLVC sensorless vector control, built‑in PID function for closed‑loop process regulation.
• Strong Overload Capability 200% overload for 3s, 150% overload for 57s within 300‑second cycle, meets heavy‑duty startup requirements.
• Complete Built‑in Protection Over‑voltage, under‑voltage, over‑current, over‑temperature, motor overload, short‑circuit and stall protection, effectively safeguards motor and drive.
