1.75 kW / 11 Nm — what the 1FL6066 frame delivers on a V90 axis
The 1FL6066-1AC61-2AG1 is a SIMOTICS S-1FL6 low-inertia servomotor in the 1FL6 family sized for direct pairing with the SINAMICS V70 and SINAMICS V70/V90 converters, with a rated operating voltage of 3AC 400 V, a rated power of 1.75 kW at 2000 rpm, a stall torque of 11 Nm (M0) and a continuous rated torque of 8.36 Nm (MN). Stall torque of 11 Nm against a continuous 8.36 Nm tells you the motor has roughly 30 % overload headroom — enough margin to absorb indexing accel pulses on a small packaging axis or a tool-change servo, which is the typical use envelope for a 65 mm shaft-height frame in this family.
Encoder, shaft, brake — the -2AG1 suffix decoded
Configuration per the description field: incremental encoder at 2500 increments per revolution (TTL-style feedback, the standard choice for the V90), plain shaft with N tolerance, and no holding brake. Without the holding brake you need a mechanical brake elsewhere on the axis — a vertical-axis application will need a fail-safe brake on the gearbox or a different -AG1 suffix variant. The cable exit is the angle plug style with an IP65 sealing ring at the housing joint, so the motor body is rated for splash and dust in factory environments — washdown duty needs a higher IP rating than what is stated here.
Lifecycle is NRND — the sourcing posture for this code
Lifecycle stage reads NRND (Not Recommended for New Designs) — the motor is still serviceable and available to ship, but Siemens has flagged the family for replacement planning on new machine builds. Existing fleets keep running; spares are real but the window is finite. Product class C applies: manufactured to order with no return-for-credit, so any RFQ has to be sized against the actual BOM quantity. Plan the spares count carefully — a five-year MRO window on an NRND part can outlive the factory's willingness to build it.
Compliance pack and export classification
RoHS compliance is documented from 01-01-18 onward, and REACH Article 33 duty-to-inform applies per the current candidate list. Export control is AL:N / ECCN:N — no special licence required for cross-border shipment under the listed classifications.
Integration with SINAMICS V70 and V90
The motor is released as compatible with the SINAMICS V70 and SINAMICS V70/V90 converter families, which is the same vendor ecosystem the encoder pitch and resolver emulation are tuned for — third-party drives will need an external encoder interface module to use this feedback format cleanly. Packaging per piece is 466 x 264 x 290 mm — single-unit carton, no set quantity — and the ordering unit is one piece. Group code R220, product group 5183 are the internal SAP slices used to route the line item inside the Siemens ordering system.
