Pairing it to anything other than the S200 family breaks the auto-tuning profile and the encoder map; the catalog position carries the explicit \"Matching drive SINAMICS S200\" callout (cites:). The shaft height 40 mm frame, plain shaft with tolerance N, holding brake, and IP65 sealing with oil seal set the mechanical fit: this is a flange-mounted axis intended for machine builders running position-controlled conveyors, small gantries, or pick-and-place heads where the brake holds the vertical axis at rest (cites:). ## Why the 400 V 3AC rating matters on the bench 400 V 3AC supply lets the 1FL2 sit on a standard three-phase industrial bus without a step-up transformer — the winding is built for that mains level, so the drive's DC-bus and PWM output are matched to the motor's back-EMF at 3000 rpm (cites:). Continuous torque of 3.2 Nm at rated speed lands the axis in the same envelope the SINAMICS S200 expects for a 1 kW motor; loop tuning and inertia matching are valid only when the motor and drive stay on the same power class (cites:). The AS21 hybrid connector carries both power and the absolute 21-bit encoder signal on one plug — single-cable routing, fewer gland entries on the cabinet, and the encoder remains noise-immune because the signal pair is shielded inside the same jacket (cites:). ## Compliance and ordering class Lifecycle is recorded as Active (cites:, cites:), and the part is RoHS-compliant since 01-01-18, with REACH Art. 33 information available from the manufacturer and AL:N / ECCN:N export classification (cites:, cites:, cites:). The product is classed C — built to order, not re-usable and not returnable for credit — so the BOM line should be sized to the actual axis count rather than padded as a service spare (cites:, cites:). ## Sourcing posture With no authorized distributor of the Siemens S200 line on the open shelf, the realistic path for a single-axis spare or a small builder run is an RFQ against an independent industrial automation supplier — the build-to-order class means lead time is confirmed at quote time, not at order acknowledgment (cites:, cites:, cites:). Shipping footprint per piece is 382 x 222 x 240 mm (cites:), which matters for panel builders planning a multi-axis drop or a panel-builder kitting job where a full crate has to be checked into incoming inspection (cites:, cites:).","metaTitle":"Siemens 1FL2104-4AF11-0SC0 Servo Motor, 1 kW, 400 V 3AC","metaDescription":"Siemens 1FL2104-4AF11-0SC0 SIMOTICS 1FL2 servo, 1 kW, 400 V 3AC, 3000 rpm, 3.2 Nm, IP65 with holding brake.
