What this motor is and where it sits in the SINAMICS S210 line
The 1FK2204-5AK10-0SA0: The part is a SIMOTICS S-1FK2 CT servo motor built for the SINAMICS S210 drive family, frame code R220 in product group 9021, and the catalog lists it as class C — built to order, non-returnable, so every line on the BOM has to be confirmed against an actual RFQ rather than pulled from generic stock. Rated torque M0 = 2.4 Nm with two power points on the nameplate: 0.57 kW at nN = 6000 rpm on the 380-480 V supply and 0.75 kW at nN = 3000 rpm on the 200-240 V supply. That dual rating is the practical decision point — the same motor mechanically, but the S210 drive sizing and the line-supply feed change between a 400 V European cabinet and a 230 V North American build.
Holding brake, encoder, and the panel-side wiring face
It ships with a holding brake — the holding torque should be sized against the vertical-axis load it has to lock at standstill, not against the motor's continuous torque — and the feedback side is an absolute single-turn 22-bit encoder AS22DQC delivered over the OCC interface. Single-turn absolute is the right call for point-to-point motion where the drive homes on power-up; if the application needs retention across power cycles, the 1FK2 multi-turn variant in the same mechanical frame is the sibling to spec instead. The shaft end is a plain cylindrical D19 × 40 mm stub and the power/feedback connector is an M17 rotatable plug — rotatable matters at panel-build because the harness lay can be rotated to the cable-tray side without reorienting the motor on the gearbox. Degree of protection IP64 means the body tolerates dust and splashing from any direction but is not rated for washdown; a hygienic or outdoor-exposed axis needs a higher-IP variant from the 1FK2 family.
Lifecycle, compliance, and what the BOM line actually costs
Lifecycle stage reads current on the order record and the product status is Active — the part is not on a last-time-buy clock, but the class-C build-to-order designation is the caveat: production quantities are scheduled against the order, not pulled from a finished-goods buffer, so quote lead time and not shelf availability is what drives the delivery date. On compliance the record is plain: RoHS conformity since 01-07-06, REACH Art. 33 duty-to-inform against the current candidate list, and export classification AL:N / ECCN:N_CNDU — no special license gate for cross-border shipment into the usual industrial markets, and the substance-restriction posture is current as of the record date. Each unit ships one per package in a 452 × 250 × 267 mm carton, so inbound handling is a single-piece lift and the receiving dock can plan around a motor-and-brake crate rather than a multi-up pack.
