SIMOTICS S-1FK2 HD, sized for a 0.75 kW SINAMICS S210 axis
The Siemens 1FK2104-5AF01-0SA0 is a SIMOTICS S-1FK2 HD servo motor from the 1FK2 family that pairs with SINAMICS S210 drives, holding M0=2.4 Nm of stall torque with a rated PN=0.75 kW at nN=3000 rpm on a 380-480 V rail, and a derated PN=0.375 kW at nN=1500 rpm on a 200-240 V rail — so the same frame covers both the high-voltage European drive and the 230 V North-American panel without a re-spec. Feedback is an absolute single-turn 22-bit encoder (AS22DQC) delivered over the OCC connector interface, which is the position feedback the S210 expects — a relative encoder or a third-party multi-turn unit will not drop in without a parameter and wiring change. The 0.75 kW / 2.4 Nm envelope puts this motor in the small-format S210 cell where the drive is doing the commutation and the motor is sized for short-stroke packaging, labelling, and small-format indexing tables rather than conveyor or spindle duty.
Shaft, sealing, and the M17 plug that survives a panel builder's day
Mechanical package is a cylindrical D19x40 mm shaft with IP65 protection on the body, which is enough to shrug off coolant mist and washdown splash in a packaging cell but is not an IP67 food-zone rating — keep the shaft seal away from direct jet exposure. The power and feedback plug is M17 and rotatable, so the cable gland can be oriented after the motor is bolted down without re-terminating — a small detail that saves real time when the cable tray lands on the wrong side of the machine.
Lifecycle and ordering reality for a build-to-order SIMOTICS line
Lifecycle stage is current, and the listing is product class C — built-to-order, no returns, no reuse credit — which is the normal posture for a configured SIMOTICS servo; specify the encoder variant and plug orientation once and order against that frozen BOM line. Compliance paperwork on file covers RoHS since 01-07-06 and REACH Art. 33 candidate-list disclosure, with export classed AL:N / ECCN:N_CNDU — no licence trigger for standard commercial shipment.
Traceability fields the buyer side will ask about
Group Code R220 / Product Group 9021 are the internal Siemens classification tags that travel on the packing list and the nameplate, useful when the receiving inspector cross-checks the PO line against the shipper. Single-piece quantity unit in a 452 x 250 x 267 mm pack; product family is the 1FK2 series for SINAMICS S210, so any cross-reference search should stay inside the 1FK2 family rather than branching to the older 1FK7 or 1FT7 lines.
