Drive fit and ratings
The Siemens 6SL3211-0AB21-1UA0 is a SINAMICS G110 CPM110 AC drive rated for 1.1 kW constant torque and 1.1 kW variable torque on a single-phase 200-240 VAC supply (+10%/-10%, 47-63 Hz). The CT-overload capability is 150% for 60 seconds, which means it can handle brief overloads on pump, fan, or conveyor loads without tripping — sized for a 1.1 kW motor, not a derated larger one. The drive accepts an analog input for speed reference and is protected to IP20, so it mounts inside a control cabinet or enclosure — not in a washdown or outdoor location. Ambient temperature range is -10 to +50 °C. No built-in BOP (Basic Operator Panel) or RS-485 interface is included; commissioning requires an external operator panel or PC connection.
