What this motor delivers on the SINAMICS S120 bus
The Siemens 1FK2104-6AF01-0MB0 is a SIMOTICS S-1FK2 HD servomotor from the 1FK2 product family sized for SINAMICS S120 drive commissioning through the DRIVE-CLiQ M17 interface, so the motor and drive pair without an external encoder cable run. Rated output PN = 1 kW at nN = 3000 rpm on a 380-480 V supply, with a 200-240 V derated point of PN = 0.5 kW at nN = 1500 rpm — the higher rail is the one to plan cabinet wiring around. Stall torque M0 = 3.2 Nm puts the frame in the compact high-dynamic range, so it suits packaging, small-format converting, and auxiliary feed axes where the loop bandwidth — not raw horsepower — drives the choice.
Feedback, shaft, and sealing — the integration constraints
Feedback is the AM22DQC absolute encoder at 22-bit singleturn + 12-bit multiturn, which gives the S120 controller the absolute position the moment power comes back — a hard requirement for any axis that loses its reference after an E-stop and must resume without a homing cycle. The cylindrical shaft D19 x 40 mm and the M17 power connector sit on a housing rated IP65, meaning the motor body withstands splash and washdown but is not rated for sustained high-pressure jet cleaning — keep it out of direct hose-down zones. Packaging dimensions of 452.00 x 250.00 x 267.00 mm for a single-piece shipper signal that this frame ships as a palletised unit rather than a shelf-stock item, so plan receiving and lifting accordingly.
Order class and stocking posture
The line is flagged Product class C — products manufactured or produced to order, which cannot be reused or re-credited. For an MRO buyer that means a return-and-credit path is not available; specify into the BOM and stock critical spares at order, not as returns. Compliance paperwork is on file: RoHS conformity since 01-07-06 and REACH Art. 33 duty-to-inform per the current candidate list, with export classification AL:N / ECCN:N_CNDU — no special export licence triggers on this code. Lifecycle status is recorded as current on the manufacturer record.
Sourcing this code against an RFQ
Made-to-order class C stock from authorised Siemens channels runs against the project quantity on the BOM; we quote against the RFQ with lead time and price confirmed at quote time, and no stock count or immediacy promise is implied. Independent channels can also surface lot-specific surplus — useful for a line-down spare where the order-class return rule does not apply.
