The Siemens 6SL3211-0AB11-2UB0 is a SINAMICS G110 CPM110 AC drive rated for constant torque (CT) and variable torque (VT) at 0.12 kW. It runs on single-phase 200-240 VAC input, 47-63 Hz, without an integrated line filter. The RS-485 interface uses the USS protocol, so it talks to a Siemens PLC or HMI over a simple two-wire bus — no PROFIBUS or PROFINET on this unit. Overload capability is 150% for 60 seconds, which covers short-duration load spikes on a conveyor or pump without tripping.
Dimensions are 150 x 90 x 116 mm (HxWxD), which fits a small DIN-rail footprint. No BOP (Basic Operator Panel) is included, so parameterization is done through the RS-485 link or a PC adapter. Ambient temperature range is -10 to +50 °C, so it handles a warm cabinet but not a hot one without derating.
Lifecycle stage is marked as mature. That means Siemens still supports it, but it's not a new-design-in part. For a line-down replacement or a BOM that already specifies this order code, it's a straightforward swap.
