Drive selection memo
The Siemens 6SL3211-2AB17-5UA2 is a SINAMICS G110-CPM110 AC Drive, unfiltered, rated 0.75 kW for both constant torque (CT) and variable torque (VT) loads on a 200-240 V 1 AC supply. It delivers 150% overload for 60 seconds, which is enough to handle short-duration peak demands from a small conveyor or pump without tripping. The IP20 enclosure means it belongs in a clean, dry control cabinet — not on the machine frame where washdown or dust is present. No BOP (Basic Operator Panel) and no RS-485 interface are included, so commissioning and parameter access require a separate BOP or PC connection via the USS/MODBUS port if the drive supports it.
Lifecycle and sourcing reality
Mature status is acceptable for a BOM freeze or line-down spare. Confirm availability at quote time since allocation can tighten.
What the ratings mean for fit
The 0.75 kW CT rating governs motor starting torque — sized for a standard 1 HP (0.75 kW) induction motor on a constant-torque load like a positive-displacement pump or a small conveyor. The VT rating matches the same 0.75 kW for variable-torque loads (centrifugal fans, pumps) where the torque demand rises with speed squared. Ambient temperature range of -10 to +40 °C is typical for indoor panel environments; derate above 40 °C per the thermal curve in the manual. Dimensions 150 x 90 x 131 mm (HxWxD) — fits a standard 200 mm deep enclosure with room for a disconnect upstream.
