That overload headroom means it can handle short-duration peak loads — a conveyor start or a pump breakaway torque — without tripping or needing a larger frame. The drive integrates Safe Torque Off (STO) as standard, eliminating the need for a separate safety relay in many guarding circuits. The I/O complement is 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 USS/MODBUS RTU onboard; for PROFINET or EtherNet/IP you would add a communication board in the slot.","metaTitle":"Siemens 6SL3210-1KE21-7UB0 SINAMICS G120C, 7.5kW, 380-480V,","metaDescription":"Siemens SINAMICS G120C drive, 7.5kW, 380-480V 3AC, 150% overload, Safe Torque Off, USS/MODBUS RTU.
