The Siemens 6SL3211-0AB21-1UA1 is a SINAMICS G110-CPM110 AC drive sized for a 1.1 kW motor on a 200-240 V single-phase supply. It's an unfiltered unit — expect to add an external line filter if the installation requires conducted-emission limits per EN 61800-3 Category C2 or C1. The IP20 enclosure means it belongs in a clean, dry cabinet, not on the machine frame exposed to washdown or dust.
The 1.1 kW rating applies to both constant-torque (CT) and variable-torque (VT) loads at the stated input voltage. CT overload capability is 150% for 60 seconds — enough for a conveyor start or a small extruder breakaway, but not for a high-inertia centrifuge that needs 180% for 30 s. The input accepts 200-240 V 1 AC at 47-63 Hz, so it runs on standard North American 208/240 V single-phase shop power or European 230 V single-phase mains. The analog input is the only control interface; there's no built-in RS-485 or BOP (Basic Operator Panel), so parameterization requires the optional BOP or a PC connection via the SINAMICS G110 commissioning tool.
Ambient temperature range is -10 to +50 °C — derate output current above 40 °C per the thermal curve in the operating instructions. The unfiltered input stage draws peak inrush at power-up; size the upstream protective device accordingly (typically a 16 A Type C MCB for a 1.1 kW drive on 230 V single-phase).
