Where the 1FL2203-4AG11-1SC0 sits in a SINAMICS S200 cabinet
The 1FL2203-4AG11-1SC0 is a SIMOTICS S-1FL2 low-inertia servo motor built to pair with the SINAMICS S200 drive family, and its 30 mm shaft height combined with a 0.4 kW continuous rating frames it for small-format positioning axes — labeling, light conveyor drives, indexing tables, and feeder stations — rather than high-load machine tool spindles. Holding torque is specified at 1.27 Nm for both M0 and Mn, which means the rotor delivers the same rated torque at standstill as under the 3000 rpm nominal speed; the shaft-key + N-tolerance stack-up keeps backlash tight enough for a direct-coupled load without a downstream gearbox on light-duty indexers.
Ratings that determine the BOM line
Supply is single-rail 200 V 3AC — the motor parks inside the S200's standard 200V class, so no step-up transformer is needed in a 200V cabinet; the 3 kHz nominal speed at 1.27 Nm sits inside the S200's continuous-duty map and the resolver / hybrid connector is pre-mapped to the drive side of the family. IP65 with oil seal plus a factory-installed holding brake locks the motor into its cabinet envelope — the seal keeps oil-mist out of the bearing housing when the axis lives next to a gearbox or a pneumatic bank, and the holding brake is sized to lock the rotor at standstill so a vertical axis won't drift on power loss without a separate mechanical brake. Encoder is a 21-bit hybrid-feedback device wired through the AS21 connector — absolute position survives power cycle, which removes the home-return routine from every machine start-up and lets the S200 firmware pick up where the line left off after an E-stop.
Ordering and compliance documentation on file
The order code is built per the Siemens group/product scheme (Group Code R220, Product Group X0DJ) and ships one piece per package in a 315 x 182 x 172 mm box — non-returnable per the listed product class C clause, so commissioning has to be clean before the part leaves the dock. Compliance paperwork on file covers RoHS compliance since 01-01-18 and REACH Art. 33 candidate-list information; export control is AL:N / ECCN:N, so no special license is needed for routine cross-border shipment into standard industrial destinations. Lifecycle is currently active on the family; no LTB or PCN is named here, but 1FL2 is a configured product line with manufactured-to-order lead times — call the requirement in with the full configuration string so the factory-side build slot is locked.
