Defining the 1FL2 shaft
The 1FL2104-2AF10-1MC0: SIMOTICS S-1FL2 is Siemens' low-inertia synchronous servo for the SINAMICS S200 drive platform — the compact sibling slot of the SIMOTICS family, sized for point-to-point motion, light positioning axes, and short-cycle feed drives where a 0.75 kW continuous rating covers the load. Pn=0.75 kW at Nn=3000 rpm with M0=2.4 Nm continuous and Mn=2.4 Nm rated is a short-duty inertia-matched motor — meaning it delivers rated torque across the working speed range with limited thermal margin, so cyclic overload must be planned against the SINAMICS S200 current limit, not assumed from the headline number alone. Shaft height 40 mm, IP54 housing without oil seal, hybrid cable connector AM21bit, 21-bit encoder, holding brake, and N-tolerance shaft with key are all locked into the variant suffix, so a board-level swap is impossible — replacing this motor requires the identical -1MC0 configuration on the BOM.
Sizing against the S200 drive pair
Pairing this motor with the SINAMICS S200 means the drive auto-commission mode recognises the 1FL2 electronic nameplate on first connect — wiring the 400 V 3AC supply to the drive, routing the hybrid AM21bit cable between motor and drive, and letting the S200 read the encoder parameters avoids a manual motor-ID step on startup. The holding brake is wired through the S200 brake output and is dimensioned to hold the rotor at zero speed — it is not a dynamic braking device, so any controlled stop with energy absorption has to use the drive's regen or external resistor path on the DC bus. IP54 with no oil seal keeps the motor body splash-resistant for typical cabinet-adjacent machine frames, but a washdown or food-grade line needs an OEM-rated sealed variant — the listed rating is the housing protection, not the shaft seal performance.
Ordering class and compliance footprint
Product class C means the unit is built to order against a confirmed BOM line — stock returns and reuse credits are not on the table, so lead time is set by the Siemens order intake window rather than shelf availability, and procurement should plan the motor into the BOM early rather than as a last-week add. RoHS compliance has been declared since 01-01-18 and REACH Art. 33 candidate-list information is supplied with the product, satisfying the substance-restriction documentation typically required by EU machinery integrators; export control lists AL:N / ECCN:N keep the unit outside the controlled-goods gate.
Codes the planner sees on the PO line
Group Code R220 and Product Group X0DK are the Siemens-internal classification fields that show on order acknowledgements and packing-list line entries — quoting them back to Siemens or to an authorised channel confirms the exact 1FL2 variant is being sourced rather than a visually similar 1FK or 1FT sibling. Packaging is one piece per carton with outer dimensions 382 x 222 x 240 mm, so a single-unit spare fits a standard shelf cell and the receiving bay can plan for one carton per order line rather than bulk handling.
