Where the 1FL2 slots into a cell
The Siemens 1FL2103-4AF00-0SC0 is a SIMOTICS 1FL2 low-inertia servomotor in the 30 mm shaft-height frame, specified for 400 V 3AC supply with a rated power of 0.4 kW at 3000 rpm and a continuous stall and rated torque of 1.27 Nm on both sides of the nameplate. It is the matching motor for the SINAMICS S200 drive line, so the cable set, encoder protocol, and commissioning toolchain are the same family as the drive it bolts to. The plain-shaft, no-holding-brake variant with hybrid connector and 21-bit absolute encoder is what the order code breaks down to — the absence of a brake simplifies the cabinet wiring on a free-standing axis (conveyor idler, small indexing table, light pick-and-place), where gravity load is held mechanically and the drive's regenerative stop is sufficient.
Panel-side mounting and the IP54 envelope
Packaging lands at 315 x 182 x 172 mm for a single piece, so the receiving inspection bench needs clearance for the motor carton before the unit is committed to a machine build. IP54 without an oil seal is the as-shipped rating — the motor tolerates dust ingress and light splash but is not the right call for a washdown station or a gearbox breather zone where oil mist is continuous; a sealed-shaft option belongs in those locations.
Lifecycle and the BOM position
The declaration pack a quality doc-control owner would expect for an EU-shipped build is covered by those two; any additional UL/IEC motor standard attestations beyond RoHS/REACH are not in this spec bundle and would need to be requested against the project file.
Catalog codes worth pinning to the PO line
Group code R220 and product group X0DJ are the Siemens internal classifications that travel with the part in the configurator and the packing list — pin them on the purchase order so the receiving inspection line can reconcile nameplate to PO without re-keying the full order code. Quantity unit is 1 piece and the packaging quantity is 1, so a multi-axis build orders N motors as N line items, not as a kit.
