What this motor is and where it sits
Siemens SIMOTICS S-1FL2 low-inertia servomotor, order code 1FL2203-4AG00-0MC0, designed as the rotating half of a SINAMICS S200 servo drive package — the 200 V 3AC supply on the drive side feeds this motor directly, so the drive pairing is fixed by design rather than selected after the fact. Continuous rated torque M0 = Mn = 1.27 Nm at a rated speed of 3000 rpm and a rated power of 0.4 kW, in a shaft-height 30 mm frame — small enough for tabletop feeders, label applicators, indexing conveyors, and small-format packaging axes where the panel builder wants a short, stiff rotor for fast acceleration rather than a high-inertia machine.
Mechanical, feedback, and brake fit-out
Shaft is plain (no keyway), tolerance class N — convenient for clamp-style couplings and for elastomer spiders that don't need a keyed interface, but a positive-locking coupling is mandatory on any axis that can freewheel under loss of drive enable. AM21-bit hybrid encoder feedback, single-turn or multi-turn resolution depending on the S200 parameter set — sufficient for the position and speed loops used in S200 standard applications without needing a higher-end absolute encoder. No holding brake option on this order code: brake-equipped variants carry a different suffix, so a vertical axis needing a fail-safe brake has to spec a different MPN. IP54 protection class, no oil seal — fine for cabinet interiors and general industrial atmosphere, but the cable entry and shaft seal must be kept out of coolant and washdown. If the axis sits outside the cabinet on a wet line, the next step up (IP65 or IP67) is a different frame option, not a field retrofit.
Cable, connector, and the S200 drive side
Hybrid connector on the motor side carries power and encoder signals in one shell — the matching cable assembly is what gets specified alongside the motor, not a separate power and feedback cable pair, which simplifies routing on small axes. Pairing is locked to the SINAMICS S200 drive family: the drive auto-recognises the motor via the encoder ID, so commissioning is a matter of selecting the motor code in the S200 wizard rather than entering the electrical data by hand. Shipping pack is a single piece at 315 × 182 × 172 mm — sized for shelf storage of a single spare, but if a spare-parts cabinet is being stocked for a multi-axis line, expect one carton per motor on the receiving dock.
Compliance, documentation, and export
RoHS compliance declared since 01-01-18, REACH Article 33 duty-to-inform status confirmed on the manufacturer record — so the substance-restriction paperwork on incoming inspection is in order for EU-bound panels. Export control: AL=N, ECCN=N — no licence trigger under the standard dual-use classifications, so shipments don't sit in an export-control hold.
Lifecycle posture and how to order it
Lifecycle stage is current and the part is listed as product class C — built to order against the order, not a stocked catalog item and not returnable for credit, so the BOM line should be committed before the order is released rather than treated as a shelf-spare purchase.
