What this servo delivers into the cabinet
The Siemens 1FL2204-4BF11-0HC0 is a SIMOTICS S-1FL2 low-inertia servomotor built to pair with the SINAMICS S200 drive family (cite:, cite:). On paper: 400 V 3AC supply, rated power 1 kW, rated speed 3000 rpm, with stall torque M0 and rated torque Mn both at 3.2 Nm — meaning the motor holds full torque all the way down to standstill, which is exactly what a vertical-axis pick-and-place or a small indexing table wants (cite:). Feedback is a 17-bit hybrid (AS) absolute encoder, so position loops close with sub-arc-minute resolution once the SINAMICS S200 has auto-commissioned the motor (cite:). The shaft is 40 mm frame height with a plain cylindrical output (tolerance N), and the unit ships with a holding brake — that detail matters for any gravity-loaded axis that must hold position with the bus de-energised (cite:).
Mechanical and environmental envelope
Protection class is IP65 with oil seal on the shaft, which keeps the encoder and bearing cavity isolated from cutting-fluid splash and conveyor-side lubricant mist — a typical fit for machine-tool feeders, packaging lines and small gantry axes close to the process (cite:). The hybrid connector carries power and feedback in one moulded shell, so cabinet-side wiring is one plug rather than a separate power and signal pair. Shipping footprint is 382.00 x 222.00 x 240.00 mm for a single-piece pack, so plan the receiving bench and the cabinet cutout around a motor that arrives in a printer-paper-plus sized box rather than a small parcel (cite:).
Lifecycle, compliance, commercial class
Lifecycle stage is marked current on the manufacturer record, and the product is active in the Siemens 1FL2 programme — no LTB notice or PCN on file for this order code (cite:, cite:). Compliance: RoHS conformity since 01-01-18, with REACH Art. 33 duty-to-inform carried through the supply chain on request (cite:, cite:). Commercial class is the Siemens 'C' code: built to order, non-returnable, non-reusable (cite:). For a procurement line that means RFQ quantities drop straight into build slots rather than being pulled from shelf stock — lead time and price are confirmed against the BOM at quote.
Sourcing posture
The 1FL2204-4BF11-0HC0 is sourced through independent distribution against the buyer's RFQ: build-slot confirmation, current pricing and delivery window are returned at quote time. There is no lot-stock claim on a made-to-order C-class line — the answer to 'in stock' is the factory allocation calendar, not a warehouse shelf.
