What lands on the bench when this code is opened
The 1FK2204-5AK01-1SB0 is a SIMOTICS S-1FK2 CT servo motor sized for SINAMICS S120 — a compact synchronous unit rated M0 = 2.4 Nm with PN = 0.57 kW at nN = 6000 rpm on a 380-480 V bus, and PN = 0.75 kW at nN = 3000 rpm on a 200-240 V bus. The shaft is D19x40 mm with a feather key, the absolute encoder is single-turn 22-bit (AS22DQC), and both feedback and power exit through M17 connectors with a DRIVE-CLiQ plug. Because the rating is locked to 8 kHz / 62.5 µs current-controller cycles, the drive side has to be parameterized to that pulse pattern — bolting it to a default 4 kHz profile will not deliver the rated torque. Holding torque of 2.4 Nm puts it in the low-inertia compact class used on small packaging, pick-and-place, and feed-axes where the load inertia is a fraction of the rotor — anything heavier than roughly a 5:1 ratio wants a gearbox or a frame up. The IP65 rating on the housing and the M17 connector family keep the motor sealed against coolant mist and washdown residue typical of these lines, which is the deployment context this frame was designed into rather than a clean-room assembly cell.
Series, codes, and compliance pack
The motor sits inside the 1FK2 family for SINAMICS S120 drives, listed under Group Code R220 and Product Group 9021 — useful filters when pulling this part out of the Siemens configurator or matching it against a BOM line that already carries those codes. Compliance carries RoHS conformity since 01-07-06 and a current REACH Art. 33 candidate-list disclosure; export classification is AL:N / ECCN:N_CNDU, so the part ships without an export-license gate in most jurisdictions. Production status is active per the lifecycle record. The product class is non-returnable / non-reusable (class C) — it is built to order, so any kit pulled for a line-down spare needs the full order code committed up front, not a generic 1FK2 substitute drawn from shelf stock.
Handling footprint and what ships in the carton
Packaging is one piece per carton with outer dimensions of 452 x 250 x 267 mm — the motor itself is compact, but the shipper box is sized for the encoder-protective foam and the connector caps, so the receiving dock needs to plan floor space accordingly. The carton is not field-recoverable once opened: the part class designation means returns against credit are not accepted, which is worth flagging in the receiving SOP before the unit goes into stores.
