The Siemens 6SL3210-1KE12-3AC0 is a SINAMICS G120C compact drive rated for 0.75 kW output power on a 3-phase 380-480 VAC supply, with a 150% overload capability for 3 seconds. It integrates a Class A EMC filter, a CANopen fieldbus interface, and Safe Torque Off (STO) as standard. The FSA frame size (196x73x203 mm) and IP20 / UL Open Type protection suit it for enclosure mounting in control panels where space is tight.
Ratings and what they mean for fit
The 150% overload for 3 seconds is the key duty-cycle spec: it means the drive can deliver 1.125 kW momentarily for starting or heavy-breakaway loads (conveyors, mixers) without tripping, but continuous rating remains 0.75 kW. The 380-480 VAC +10/-20% input range covers standard European and North American industrial mains (400 V, 460 V, 480 V nominal) with tolerance for weak grids. The integrated Class A filter meets EN 61800-3 for conducted emissions in an industrial environment — no external filter needed for most installations, but a Class B filter would be required for residential or public low-voltage networks.
I/O and safety integration
The I/O interface provides 6 digital inputs, 2 digital outputs, 1 analog input, and 1 analog output — enough for basic speed/start/stop control and feedback without an add-on module. Safe Torque Off (STO) is integrated per IEC 61800-5-2, so you can wire an emergency-stop circuit directly to the drive terminals without a separate safety relay, reducing panel wiring and component count. The CANopen interface uses the standard DS402 drive profile, making it drop-in replaceable for any CANopen master.
