Drive specs and fit
The Siemens 6SL3211-0AB21-1AB0 is a SINAMICS G110 CPM110 AC drive rated for 1.1 kW in both constant-torque (CT) and variable-torque (VT) applications, fed from a single-phase 200–240 VAC supply (+10/-10%, 47–63 Hz). The built-in Class A EMC filter means it meets conducted-emission limits for industrial environments — no external filter needed for most European or North American industrial panels, but verify if your installation requires Class B (residential) compliance. Communication is via the RS485 interface running the USS protocol, so it integrates directly with Siemens PLCs or any host supporting USS. No analog input is populated on this variant — control is serial-only unless you add the optional BOP (Basic Operator Panel). The CT overload rating of 150% for 60 seconds means it handles short-duration load spikes typical of conveyors or small pumps without tripping. Ambient temperature range is -10 to +50 °C, with the IP20 enclosure suited for clean, dry cabinet mounting — not washdown or outdoor locations.
This drive carries a lifecycle stage of mature, meaning it is an established, stable product that Siemens continues to support but is no longer the newest platform in the SINAMICS family. For a BOM line or line-down replacement, the 6SL3211-0AB21-1AB0 is a known-quantity fit — the 1.1 kW rating at 200-240V single-phase input matches a specific niche that later SINAMICS V20 or G120C drives may not cover without a transformer or derating.
Dimensions are 160 x 140 x 142 mm (H x W x D), so it fits a standard small-drive footprint on a backplate or DIN rail.
