The Siemens 6SL3211-0KB11-2BB1 is a SINAMICS G110-CPM110 AC Drive marked as a spare part, rated 0.12 kW constant torque and 0.12 kW variable torque on a 200-240 V 1 AC supply with integrated filter B. It communicates over RS-485 via the USS protocol, and the IP20 enclosure with a flat heat sink is designed exclusively for cooling plate installation — no fan, no through-panel airflow, so the mounting surface does the thermal work. Ambient range is -10 to +50 °C; there is no BOP (basic operator panel) and no analog input on this variant.
Mounting is cooling-plate only — the flat heat sink must mate directly to a metallic panel or machine frame that acts as the thermal dissipator. No standoffs, no DIN-rail clip; the drive is screwed flat. The 150 x 90 x 101 mm (HxWxD) footprint is compact enough for a small control cabinet or machine-mount pocket. The integrated filter B covers conducted emissions for the 200-240 V single-phase supply, which simplifies EMC compliance in a panel build — no external line filter needed for most industrial environments.
The CT overload capability is 150 % for 60 seconds, which gives headroom for starting a small pump or fan without oversizing the drive. The RS-485 USS interface is straightforward for point-to-point or simple multi-drop networks — no PROFIBUS or PROFINET on this unit, so plan the control architecture accordingly. If the application needs analog speed reference or a local operator panel, this variant omits both; the BOP and AI are not fitted.
