The Siemens 6SL3211-0KB12-5BA0 is a SINAMICS G110 CPM110 AC drive rated 0.25 kW in both constant-torque (CT) and variable-torque (VT) modes, fed from a single-phase 200-240 VAC supply at 47-63 Hz. Built-in Class B EMC filter eliminates the need for an external filter in most residential or light-industrial environments — saves panel space and one wiring step. The drive includes an analog input for speed reference, and its CT-overload capability is 150% for 60 seconds, which handles short-duration peak loads like a crusher jam or a cold-start pump without tripping. Ambient temperature range is -10 to +50 °C without the optional BOP (Basic Operator Panel).
The drive measures 150 x 90 x 101 mm (HxWxD) and is designed for DIN-rail mounting inside a control panel. It ships without a heatsink — the drive relies on the panel's internal airflow for cooling, so ensure adequate ventilation around the unit. The single-phase input simplifies wiring: L and N in, motor U/V/W out. The analog input accepts a 0-10 V or 4-20 mA signal from a PLC or potentiometer.
