The 6SL3211-0KB12-5UB0 is a Siemens SINAMICS G110 CPM110 AC drive rated for 0.25 kW in both constant-torque (CT) and variable-torque (VT) applications, fed from a single-phase 200-240 VAC supply. It's the no-filter variant, so on a line with dirty power or tight EMC emissions limits you'll want to add an external line filter — the drive itself handles 47-63 Hz input. The RS485 interface speaks USS protocol, which is Siemens' Modbus-like serial for simple point-to-point or multi-drop control without a fieldbus gateway.
What the ratings mean for your panel
The 150% overload for 60 seconds (CT rating) means this drive can handle a 0.25 kW motor pulling 1.5x rated current during startup or a jam — enough for a small conveyor or pump, not for a high-inertia fan that needs a longer ramp. The IP20 enclosure and no-integral-heatsink design means it's meant for a clean, ventilated cabinet; mount it with the 150 x 90 x 101 mm (HxWxD) footprint on a DIN rail or backplate, and keep ambient between -10 and +50 °C. Without the BOP (Basic Operator Panel), you'll commission it via the USS serial link or a simple I/O terminal block.
