Drive selection memo: SINAMICS G120C, 1.5 kW
The Siemens 6SL3210-1KE14-3UF1 is a SINAMICS G120C compact drive rated for 1.5 kW output with a 150% overload capability for 3 seconds, sized for a standard 380-480 VAC three-phase supply at 47-63 Hz. It integrates PROFINET PN fieldbus and Safe-Torque-Off as standard, so it drops into a safety-rated motion chain without a separate safety relay for the stop function. The I/O complement — 6 digital inputs, 2 digital outputs, 1 analog input, 1 analog output — covers basic conveyor or pump control without an expansion module. Housed in an IP20 / UL Open Type enclosure at FSA frame size (196 x 73 x 225.4 mm), it mounts inside a control cabinet; the external 24 V supply powers the control logic separately from the DC link.
Sourcing and lifecycle posture
For BOM planning, the 6SL3210-1KE14-3UF1 is a fast mover in the G120C line; keep one on the shelf if your line runs multiple 1.5 kW motors on 400 VAC.
Integration notes
The unfiltered variant means it expects a line reactor or external EMC filter if the installation must meet EN 61800-3 Category C2 or C3 conducted emissions limits — check the cabinet-level filter spec before commissioning. PROFINET PN is onboard, so no option card is required for the fieldbus connection; the Safe-Torque-Off input is a dedicated terminal pair, separate from the digital I/O.
