Drive selection memo — 2.2 kW on 400 VAC
The Siemens 6SL3210-1KE15-8UP0 is a SINAMICS G120C frequency converter rated for 2.2 kW output power with a 150% overload capability sustained for 3 seconds. Input accepts 380-480 VAC three-phase, +10%/-20%, 47-63 Hz, unfiltered. This overload profile suits applications like conveyors or pumps where short-duration torque spikes occur during start-up or load changes — the 150% figure is the peak torque margin, not continuous duty. The I/O complement is six digital inputs, two digital outputs, one analog input, and one analog output. Safe Torque-Off is integrated, eliminating the need for a separate safety relay on the motor branch for controlled stop functions. Fieldbus is PROFIBUS DP, so this unit drops into a DP network without an external gateway module.
