Pair-and-fit on the SINAMICS S200 rail
The Siemens 1FL2104-2AG00-0SC0 is a SIMOTICS S-1FL2 servomotor from the 1FL2 family built to pair with the SINAMICS S200 drive — the description block ties the motor to the S200 explicitly, and the family line confirms that pairing as its primary use. On a controls integrator's bench that means the drive configures the motor in one entry rather than as a vendor-neutral third-party servo. Power is supplied 200 V three-phase at 0.75 kW rated against the SINAMICS S200, so the drive feed is fixed by the order code — applying a 400 V-class converter to this winding is a misapplication the BOM line must reject before the panel build starts.
Headline ratings and what they govern
Continuous rating sits at Pn=0.75 kW with a rated speed Nn=3000 rpm and M0=Mn=2.4 Nm — equal standstill and rated torque tells you there is no constant-power region traded away for top speed, and 0.75 kW at 3000 rpm checks out as roughly the headline torque on the order code. That is the load point the sizing calc has to land on, not the marketing peak. The shaft-height-40 mechanical envelope with a plain shaft, tolerance N, and no holding brake sets what fits on the machine side: an unbraked shaft mounted to a coupling or gearbox, balanced and aligned to the N tolerance — adding a holding brake or a key seat needs a different order-code variant. Protection is IP54 with no oil seal, sufficient for an enclosure or a typical machine interior but not a washdown bay. Feedback is an AS21-bit absolute encoder on a hybrid connector — the hybrid connector carries power and encoder in one shell, which is the wiring-time win a commissioning engineer actually feels at first power-up.
Lifecycle, order class, and what that means for the BOM
Lifecycle status on file is active under productStatus Active with current, so this is not an end-of-life buy — the order code is the live S200-paired motor and any replacement must keep the S200 compatibility. Product class is C — built to order, no return-for-credit path — and the unit ships one piece at a time. Quantities, lead times, and price breaks are confirmed against an RFQ rather than pulled from a stock shelf. Logistics footprint is one piece per pack at 382 x 222 x 240 mm — a single motor, but the carton is sized for a cushioned shipper rather than a hand-carry, worth knowing on a panel-day green-light.
