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.
Lifecycle and sourcing
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. It remains available through distribution channels and is sourced to order against an RFQ. 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. Availability and current pricing are confirmed at quote time.
Panel integration notes
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. The IP20 rating means it is intended for enclosure mounting with adequate clearance for airflow — no forced cooling required at rated load up to 50 °C ambient, but check the thermal derating curve if mounting side-by-side with other heat sources.
