The Siemens 6SL3210-1KE14-3AP0 is a SINAMICS G120C compact drive rated for 1.5 kW output power on a 380-480 VAC three-phase supply, with a 150% overload capability sustained for 3 seconds. That overload headroom matters for short-duration peak loads like a conveyor start or a quick acceleration ramp — the drive doesn't trip on a momentary current spike, but it's not a continuous rating.
I/O and fieldbus integration
The onboard I/O includes 6 digital inputs, 2 digital outputs, 1 analog input, and 1 analog output — enough for basic speed control and status feedback without an expansion module. PROFIBUS DP is integrated on the unit, so a separate communication module isn't needed; the drive connects directly to a PROFIBUS DP master via the standard 9-pin D-sub connector. Safe-Torque-Off (STO) is also integrated, which eliminates the need for an external safety relay in many guarding applications — the drive itself can remove torque from the motor shaft on a safety demand.
