Headline rating and what it actually gives the axis
The Siemens 1FL6066-1AC61-2AA1 is a SIMOTICS S-1FL6 servomotor sized at Pn=1.75 kW with a rated speed Nn=2000 rpm, MN=8.36 Nm continuous and M0=11 Nm standstill, on a 3AC 400 V bus — the MN figure is the one that gates sizing against the mechanical load, with the M0 margin reserved for acceleration peaks, not for continuous duty. Feedback is an incremental encoder at 2500 increments/revolution with a feather key and tolerance N, shaft height 65 mm, and the angle-plug connector orientation — meaning the resolver/encoder cable routing is fixed at the plug face and must match the harness bend radius at panel entry, not be re-oriented after the fact. IP65 with the sealing ring means the body and connector face tolerate plant-side washdown and oil mist but are not rated for submerged or high-pressure cleaning — sealed enough for a packaging or conveyor cell, not for a hygienic-zone washdown station.
Drive pairing and commissioning reality
Listed as compatible with the SINAMICS V70 and V90 converter families, so the motor plugs into the standard 1FL6 parameter set on those drives — no firmware workaround for encoder scaling, since the 2500 incr/rev incremental is the native feedback format those drives expect on this frame. No holding brake on this build, which simplifies the wiring diagram and the BTB contactor logic — but means the axis relies on the mechanical brake downstream or on the drive's stop-category behaviour to hold position on power loss, a constraint to flag on the SAT before the load is hung.
Lifecycle status and sourcing posture
Product class is C — manufactured/produced to order, which cannot be reused or re-utilized or returned against credit — so any order placed is a firm build commitment; cancellation or returns are not a lever once production is queued.
Compliance, paperwork, and shipping geometry
Packaging is 1 piece per unit at 392.00 x 269.00 x 290.00 mm — a single-motor carton that fits a standard parcel shelf and needs no forklift at the receiving dock, useful for MRO spares that arrive unannounced.
