Siemens 1FL2304-2AF01-0SB0 is a member of the SIMOTICS S-1FL2 low-inertia servomotor family, built to run on the SINAMICS S200 drive platform. The combined motor-and-drive pairing targets compact positioning axes where short move profiles and repeatable dynamic response matter more than the raw continuous-torque envelope. Mechanically, it is a shaft-height 45 mm flange-mount servo with a plain shaft, tolerance N, and no holding brake. The connector exits at an angle (AS angular connector) and the housing carries an IP65 protection rating with oil seal, so the body tolerates the typical coolant-mist and oil-aerosol environment of a machining cell when the connector is fully mated. Electrical envelope from the model string: 400 V three-phase supply, 0.4 kW rated power, 3000 rpm rated speed, 1.45 Nm stall torque M0, 1.27 Nm rated torque Mn. The encoder is a 21-bit absolute single-turn unit, which is what the SINAMICS S200 expects for its internal commutation and position-loop closure without a separate resolver.
Sourcing posture and lifecycle
Product class C notes that the unit is built to order and cannot be returned against credit, which is normal for configured servo motors and matters when sizing the safety stock on a project. RoHS compliance is declared since 01-01-18 and REACH Article 33 duty-to-inform applies against the current candidate list. Export control shows AL:N / ECCN:N, so the part is not subject to a U.S. export licence on its own — useful for cross-border builds but the integrator still has to check the destination country. The 1 Piece quantity unit and 382 × 222 × 240 mm single-unit pack set the inbound-logistics footprint.
Cataloging fields for the order line
Group Code R220 and Product Group X0DM are the internal Siemens classification tags carried on this order code, used internally for the drive-system accessory line under which this servo is sold. Both should be reproduced verbatim on the PO so the order does not get routed against a sister 1FL2 variant with a different winding or brake option.
