Where the S-1FL2 sits in the drive system
The 1FL2203-4AF10-1SC0 is a SIMOTICS S-1FL2 low-inertia servomotor from the 1FL2 family, built for direct pairing with the SINAMICS S200 drive — so the motor's encoder, winding and brake logic are matched at the platform level, not assembled ad-hoc from generics (cites:,). It draws 0.4 kW mechanical (Pn) from a 400 V 3-phase supply, holds a continuous 1.27 Nm standstill torque (M0) and rated torque (Mn), and runs at 3000 rpm nominal — a SH30 frame sized for small indexing axes, light gantries, and short-cycle pick-and-place heads (cites:). Encoder feedback is the absolute 21-bit variant (AS21) on a hybrid connector, and a holding brake is fitted — the SH30 + brake combination is the option most buyers use on vertical or hold-under-power axes (cites:).
Mechanical fit, shaft and sealing
Shaft height 30 mm, keyed shaft with N tolerance, no oil seal — so the unit is sealed IP54 on the body but the shaft exit is a conventional lip, suitable for clean, dry cabinet-side duty rather than wet washdown (cites:). The 315.00 x 182.00 x 172.00 mm shipping outline is the packed carton, not the motor envelope — integration planning should follow the SINAMICS S200 catalogue drawing for cutout and clearance, not the pack dimensions (cites:,).
Lifecycle status, documentation, and traceability
The product class entry notes 'products manufactured / produced to order, which cannot be reused or re-utilized or be returned against credit' — a build-to-order motor, so cancellation rights on a placed RFQ are limited (cites:). Compliance paperwork on file: RoHS conformity since 01-01-18 and REACH Article 33 disclosure under the current candidate list — the REACH entry is supplied as 'Reach Information' rather than a free-form letter, which is the typical Siemens dossier format for this product class (cites:,). The part carries no export-control flag — AL: N / ECCN: N — which keeps cross-border shipment paperwork to the usual commercial-invoice set (cites:). Internal identifiers in the record are Group Code R220 and Product Group X0DJ, useful for matching the part against existing tool-data and procurement taxonomy on a Siemens-built line (cites:,).
