Drive specs and deployment context
The Siemens 6SL3211-0KB17-5UB0 is a SINAMICS G110 CPM110 AC drive rated for 0.75 kW in both constant-torque and variable-torque duty, fed from a single-phase 200-240 VAC supply at 47-63 Hz. The CT overload capability is 150% for 60 seconds, which means it can handle short-duration peak loads like a small conveyor start or a pump breakaway torque without tripping. The IP20 enclosure (no heatsink) suits clean, indoor panel mounting — not washdown or dust-laden environments. Ambient operating range is -10 to +40 °C without the BOP (Basic Operator Panel) fitted.
Communication and integration
Communication is via RS485 using the USS protocol — a Siemens serial bus common on older automation lines. No PROFIBUS or PROFINET on this variant; the RS485 port is the only fieldbus interface. The drive dimensions are 150 x 90 x 101 mm (HxWxD), fitting a standard DIN-rail footprint typical for compact microdrives in small control panels.
