Drive spec and fit
The Siemens 6SL3211-0KB11-2UB1 is a SINAMICS G110-CPM110 AC Drive — a compact, unfiltered drive rated 0.12 kW constant torque and 0.12 kW variable torque, fed from a 200-240 V single-phase supply (47-63 Hz). The RS-485 interface runs the USS protocol, so it integrates into a simple serial network without an extra fieldbus coupler. At 0.12 kW it is sized for a fractional-horsepower motor — a small pump, fan, or conveyor drive — not a main line spindle.
