Shaft height 40 mm and the AS21bit absolute encoder close the loop on positioning axes where the S200 is the drive side of the combination. Output is delivered through a hybrid connector with shaft key, tolerance N, and no holding brake — so the motion axis must rely on the drive's regenerative handling or an external brake if vertical-load or E-stop holding is required. IP54 protection rating without an oil seal means the motor is sealed against splash and dust ingress in typical industrial cabinet-adjacent mounting, but it is not the choice for washdown or food-grade enclosures. ## Spec-led fit notes for the panel builder At 3.2 Nm continuous with a 3000 rpm ceiling, the 1FL2 frame here is sized for mid-duty packaging, small-format pick-and-place, and feed axes where the S200 drives the bus — the 400 V 3AC supply voltage matches the standard S200 three-phase input range. Continuous stall torque equals rated torque (M0=Mn), which simplifies thermal sizing because there is no S1-to-S6 derating cliff to budget into the axis selection. Product class C declares this motor is built-to-order and cannot be returned against credit once shipped — so any BOM position for a 1FL2104-4AF00-1SC0 needs the exact variant string (encoder, brake, shaft tolerance, connector) verified before the PO is cut, not after. ## Compliance and sourcing posture RoHS compliance is declared since 01-01-18, and REACH Art. 33 candidate-list disclosure applies through the standard Siemens Reach Information channel. Packaging is one piece per shipper at 382 × 222 × 240 mm — plan incoming bench space and the cabinet hoisting path around that footprint, not the bare motor dimensions, because the hybrid connector and encoder housing are protected in transit by the Siemens factory packaging. ## Spare-line planning for an active servo Because the 1FL2104-4AF00-1SC0 is class C (built-to-order, non-returnable), stocking the bare motor as a line-down spare is the procurement call rather than the sourcing call — a single MRO bench spare covers a real failure mode on a packaging axis, but the lead time should be confirmed at quote because build-to-order motors do not pull from ready inventory.","metaTitle":"Siemens 1FL2104-4AF00-1SC0 Servo Motor, 1 kW, 400 V","metaDescription":"Siemens 1FL2104-4AF00-1SC0 SIMOTICS 1FL2 servo motor for SINAMICS S200, 1 kW, 3.2 Nm, 3000 rpm, IP54, 21-bit encoder.
