What this motor is and where it belongs
The 1FL2203-4AF01-1SC0 is a SIMOTICS S-1FL2 low-inertia servomotor from the 1FL2 product family, designed and ordered as a matched drive partner for the SINAMICS S200 servo drive system. Built around a 30 mm shaft height and supplied as a single piece per order code, it carries the manufacturer's product class C designation — a build-to-order configuration that is non-returnable and built per the encoded options, so the exact option string on the nameplate must match the BOM line before commissioning.
Ratings, shaft detail, and what they mean for the axis
Rated for 400 V 3AC supply with 0.4 kW rated power at a nominal speed of 3000 rpm, and 1.27 Nm of both standstill torque (M0) and rated torque (Mn) — the equal M0 and Mn figures point to a motor sized for continuous operation at rated output rather than a high-overload profile, which is the typical signal for light-duty pick-and-place, indexing, and auxiliary axis applications rather than heavy-cycle presses or main spindle service. The shaft carries a standard key with Tolerance N fit and the unit ships without a holding brake, so any axis requiring a failsafe stopped state needs to be evaluated against an alternative option code on the same 1FL2 frame; the IP65 protection class with oil seal confirms the motor is sealed for typical factory environments but is not specified for washdown or submerged service. Feedback is the AS21 single-cable hybrid connector variant — the hybrid cable carries both power and the absolute encoder signals in one assembly, which simplifies panel routing and reduces the number of glands on the cabinet compared to a separate power-and-feedback pair, an important panel-builder consideration when the SINAMICS S200 is being mounted in a compact drive compartment.
Compliance posture for the supplier-quality sign-off
RoHS substance-restriction compliance has been declared since 01-01-18, and REACH Article 33 information is available through the manufacturer's Reach Information disclosure, both of which are the documentation hooks typically requested during a customer audit or a CE technical-file review.
Lifecycle, orderability, and the sourcing path
Lifecycle stage is recorded as current and product status is Active, so the motor remains in standard production and is sourced to order from authorised Siemens channels through independent distribution against an RFQ — pricing and lead time are confirmed at quote time against the BOM quantity. Because the order code is built to order under product class C, sourcing this part against a production BOM line requires that the full option string be locked before release; the product group X0DJ and group code R220 are the identifiers used in the manufacturer's internal order routing, useful for the procurement system that validates the Siemens catalog reference against the BOM line. Packaging is 1 piece per pack at 315.00 x 182.00 x 172.00 mm shipping dimensions — the small carton footprint is friendly to standard courier handling and to MRO shelf storage, and supports both project-build and spare-part replenishment workflows without special handling instructions.
