Drive selection memo — 2.2 kW compact VFD for 380-480 VAC lines
The Siemens 6SL3210-1KE15-8AC1 is a SINAMICS G120C variable-speed drive rated for 2.2 kW output on a 380-480 VAC three-phase supply, with 150% overload capability sustained for 3 seconds — enough headroom to start a loaded conveyor or pump without oversizing the drive frame. The integrated Class A EMC filter means this unit meets conducted-emission limits for industrial mains without an external filter, saving panel space and reducing BOM count. Safe Torque Off (STO) is built in, eliminating the need for a separate safety contactor on the motor branch when the safety circuit demands a stop category 0. Fieldbus is CANopen onboard — no optional card required for CANopen networks; the I/O complement (6 DI, 2 DQ, 1 AI, 1 AQ) covers basic speed/start commands and feedback without an expansion module.
Panel integration — FSA footprint and IP20
The FSA frame size (196 x 73 x 203 mm HxWxD) fits a standard 400 mm deep enclosure with room for a line reactor or output choke above it; IP20 / UL Open Type means it is intended for installation inside a cabinet, not in washdown or outdoor locations. External 24 V control supply is required — the drive does not derive its control voltage from the DC bus, so a separate 24 VDC power supply must be provisioned in the panel.
