The Siemens 6SL3210-1KE17-5EF1 is a SINAMICS G120C drive rated at 3.0 kW with 150% overload capability for 3 seconds, running on 380-480 VAC three-phase at 47-63 Hz. It integrates a Class A EMC filter and PROFINET PN fieldbus, plus Safe Torque Off as a standard safety feature. The FSA frame size (196 x 73 x 225.4 mm, HxWxD) keeps it compact for DIN-rail mounting in a control panel. IP20 / UL Open Type protection means it lives in a clean, dry enclosure — no washdown here.
What the ratings mean for fit
The 3.0 kW power rating at 150% overload for 3 seconds tells you this drive handles short-duration peak loads — think a conveyor start or a pump breakaway torque — without tripping. The 150% figure is the duty-cycle headroom, not the continuous rating; continuous motor load should stay at or under 3.0 kW. The integrated Class A filter means it meets EN 55011 Class A conducted emissions limits out of the box, so no external filter needed for most industrial environments — saves panel space and wiring. Safe Torque Off (STO) is integrated per IEC 61800-5-2, so you can remove motor torque without disconnecting power, simplifying safety circuit design.
Integration notes
The drive comes with 6 digital inputs, 2 digital outputs, 1 analog input, and 1 analog output — enough for basic speed control, start/stop, and fault feedback without an extra I/O module. PROFINET PN is the integrated fieldbus, so it drops into a Siemens S7-1500 or S7-1200 network with a standard GSDML file. External 24 VDC supply is required for control logic; the drive draws from that, not the main DC link, so keep the 24 V supply sized for the I/O and STO loads. Motor cable length is rated for 150 m — fine for most motor runs in a plant; longer runs need an output reactor.
