Position in the 1FK2 line and what the rating buys
1FK2204-5AF10-0SB0 is a SIMOTICS S-1FK2 CT synchronous servo motor from Siemens, built into the 1FK2 family that pairs with the SINAMICS S120 drive platform via DRIVE-CLiQ — the connector on this variant is the M17 plug, both on the power side and on the encoder side of the cable run. The headline rating is M0=2.4 Nm of stall torque with PN=0.75 kW at nN=3000 rpm on a 380-480 V bus, and PN=0.375 kW at nN=1500 rpm on the 200-240 V bus — so the same frame covers both the 400 V and the 230 V S120 line-up without a chassis swap, only a re-parameter and a bus voltage setting change at commissioning. An integrated holding brake, IP64 sealing on the body, a cylindrical shaft D19×40 mm, and an absolute encoder single-turn 22-bit (AS22DQC) close the loop without an external multi-turn battery on the encoder.
Holding-brake duty and IP64 enclosure fit
The holding brake is specified for vertical-axis and gravity-load hold, not for dynamic stopping — that is a sizing call the S120 drive handles through the brake parameter set; the motor itself ships pre-paired to the SINAMICS drive electronics, which is why the DRIVE-CLiQ plug carries both motor nameplate and brake data on insertion. IP64 means the body resists splashing and tool-coolant overspray, but it is not a washdown rating — for a wet area or food-and-bev line the cabin should be sealed at the cable glands rather than relying on the motor frame.
Production status and sourcing posture
The product is in the current lifecycle stage, classified as 'C': produced to order, non-returnable — a built-to-order posture that affects how the line lands on a master schedule, since committed delivery is what carries the slot, not shelf-pull inventory. Substance-restriction compliance has been carried since 01-07-06 under the RoHS regime, and REACH Article 33 disclosure applies to the current candidate list — the documentation trail both an EU ship-to and a North-American build will ask for at goods-in. Export-control classification reads AL:N / ECCN:N_CNDU — the part is not dual-use, which simplifies end-use paperwork; pack dimensions are 452×250×267 mm for one unit, worth knowing if the receiver dock plans single-piece flows versus lot-handling.
Catalog-coding context
Group Code R220 and Product Group 9021 are the internal Siemens classification rows used on packing documents and on the invoice line — they ride with the part number on paperwork and are useful when matching the goods-in box to the PO on a multi-line receipt.
