The Siemens 6SL3211-0KB15-5UB1 is a SINAMICS G110-CPM110 AC drive rated for 0.55 kW in both constant-torque (CT) and variable-torque (VT) applications. It runs on a 200-240 V single-phase supply at 47-63 Hz and communicates via RS-485 using the USS protocol. The drive is unfiltered and comes with a flat heat sink for cooling plate installation — no through-panel airflow, so the enclosure design needs to account for that thermal path.
What the ratings mean for your panel
The 0.55 kW CT rating means it handles constant-torque loads like conveyors and positive-displacement pumps up to that shaft power. VT rating matches the same 0.55 kW for variable-torque loads such as centrifugal fans and pumps. The 150% overload for 60 seconds gives you starting torque margin for sticky loads or short-duration peak demands. IP20 enclosure means it's for clean, dry cabinet mounting — no washdown or dust exposure. The flat heat sink requires a metal panel surface for heat conduction; ambient temperature range is -10 to +50 °C.
