The Siemens 6SL3211-0AB12-5BB0 is a SINAMICS G110 CPM110 AC drive sized for a 0.25 kW motor on single-phase 200-240 VAC input, with both constant-torque (CT) and variable-torque (VT) ratings at that same power level. The CT overload capability is 150% for 60 seconds, which covers the typical starting and short-duration peak demands of a small conveyor or pump — not a high-inertia fan where the VT curve would govern. The built-in Class B EMC filter means it meets conducted emissions limits for residential and light industrial environments without an external filter, saving a DIN-rail slot.
The 150 x 90 x 116 mm (HxWxD) IP20 enclosure mounts directly to a backplate or inside a control cabinet — no DIN-rail clip on this frame size. Ambient temperature range of -10 to +50 °C means it can sit in a non-conditioned panel near a warm process line, but derate the output current above 40 °C per the thermal curve. The RS485 USS interface handles serial communication to a PLC or operator panel; note that this variant ships without the Basic Operator Panel (BOP) and without an analog input, so all setpoint and control commands must come over the serial link or via the digital inputs.
