The Siemens 6SL3210-1KE18-8UP0 is a SINAMICS G120C variable frequency drive rated for 4.0 kW continuous power on a 380-480 VAC three-phase supply (47-63 Hz). It delivers 150% overload for 3 seconds — enough to handle short-duration load spikes on conveyors or pumps without oversizing the drive. The drive integrates Safe-Torque-Off (STO) as standard, removing the need for a separate safety contactor in many guarding circuits. Fieldbus is PROFIBUS DP onboard, so it drops into existing Siemens DP networks without an option card. I/O complement is 6 digital inputs, 2 digital outputs, 1 analog input, and 1 analog output — enough for basic speed reference and feedback without an expansion module.
