Drive selection memo — 15 kW, 380-480 VAC, PROFIBUS DP
The Siemens 6SL3210-1KE23-2UP0 is a SINAMICS G120C compact drive rated for 15.0 kW output with a 150% overload capability for 3 seconds — enough headroom for short-duration peak loads like conveyor starts or pump breakaway torque. It operates on a 380-480 VAC three-phase supply at 47-63 Hz, unfiltered, so it suits standard European and North American line voltages without an external line reactor for basic installations. Fieldbus integration is PROFIBUS DP, the mature deterministic network still common in automotive and process lines. Safe-Torque-Off (STO) is integrated, eliminating the need for a separate safety relay in many guarding circuits — the drive itself can safely remove torque from the motor shaft when the safety signal drops.
I/O and integration
The I/O interface provides 6 digital inputs, 2 digital outputs, 1 analog input, and 1 analog output — enough for basic speed reference, start/stop, and fault feedback without an expansion module.
