Servo motor spec read for the BOM line
The Siemens 1FL2204-4AF01-1MC0 is a SIMOTICS S-1FL2 low-inertia servo in the 40 mm shaft-height frame, rated 1 kW continuous at 3000 rpm with a stall and rated torque of 3.2 Nm on a 400 V 3AC supply. It ships without a holding brake, takes its feedback through the hybrid connector AM21bit at 21-bit resolution, and pairs specifically with the SINAMICS S200 drive family. Protection class IP65 with oil seal means the housing tolerates splash and dust at the cable entry — panel builders planning a washdown or machine-tool spindle application do not need a separate shroud, but the cable exit must keep the connector O-ring seated. Shaft height 40 mm and shaft-key tolerance N define the mechanical coupling envelope to the gearbox or load. Listed in product family 1FL2 servomotors for SINAMICS S200, with group code R220 and product group X0DK — those are the ordering reference strings a Siemens commerce channel uses for quote routing.
Drive pairing and control-side fit
The matched drive is the SINAMICS S200, so commissioning should be planned around that controller's auto-configuration handshake rather than a generic third-party drive — the encoder protocol, current loop tuning, and brake control wiring are scoped to that pairing. With no holding brake fitted, any vertical-axis application requires a separate mechanical brake on the gearbox or a verified back-EMF safe-stop path through the S200.
Compliance and documentation trail
RoHS compliance has been declared since 01-01-18 and the part is subject to REACH Art. 33 information-on-candidate-list duty — a supplier-quality pack should carry the current RoHS declaration and the REACH candidate-list statement for the shipment. Export control is AL:N / ECCN:N, which simplifies cross-border paperwork compared with controlled-torque parts in the same frame size. Product class is C: built to order, non-returnable. That classification matters to procurement — once the BOM line is committed, returns against credit are not available, so volume sizing and a small safety margin for spares should be settled before the build slot is opened.
Lifecycle and the sourcing question
The build-to-order class means stock is held in finished-goods flow only where Siemens has scheduled a build; volume quotes against the BOM and current pricing are confirmed through an RFQ.
