What the motor is and why the order code matters
Siemens 1FL2203-4AG00-1MC0 is a SIMOTICS S-1FL2 low-voltage servo, built as the low-inertia motor half of an S200 drive package and shipped against a BOM line, not from shelf stock (cite:,). The headline ratings — 0.4 kW continuous at Nn 3000 rpm, 1.27 Nm standstill torque matching the rated torque, 200 V 3AC supply — make it the 30 mm shaft-height frame in the 1FL2 family, intended for the small-end motion axis where a SINAMICS S200 PN is the matching drive (cite:). The order code fixes the option stack: shaft height 30 mm, hybrid AM21 connector (the single-cable feedback + power interface for the S200), 21-bit absolute encoder, shaft key with N tolerance, no holding brake, IP54 without oil seal (cite:).
Ratings decoded for the motion axis
Pn 0.4 kW at Nn 3000 rpm with M0 = Mn = 1.27 Nm means the motor delivers its full rated torque continuously from standstill to rated speed; on this small frame that continuous figure, not a higher peak, is the one that governs sizing for conveyor-indexing or pick-and-place axes (cite:). AM21 hybrid connector plus 21-bit encoder is the single-cable solution expected by the S200 ecosystem; the absence of a holding brake means the axis relies on the drive's vertical-load management or a separate mechanical brake for gravity-loaded axes (cite:). IP54 without oil seal suits dry, indoor cabinet-side mounting where the shaft is enclosed by the machine — for food-and-bev washdown or outdoor exposure the IP65/IP67 option in the same shaft height should be selected instead (cite:).
The product is classed as built-to-order (Product class C — manufactured to order, non-returnable), supplied as a single Piece with packaging 315.00 x 182.00 x 172.00 mm, which is the metric that matters for panel-builder receiving and tail-spend catalog placement rather than live inventory (cite:,). Compliance is straightforward for cross-border shipments: RoHS conformity since 01-01-18, REACH Art. 33 candidate-list information available on request, and ECCN N / AL N — no export-licensing gate applies to the standard configuration (cite:,). For an indirect-spend buyer, the practical reading is that this line belongs on a controlled, preferred-supplier channel rather than a one-off requisition — the build-to-order posture rewards catalog consolidation so the cost per PO stays below the tail-spend threshold (cite:).
