The HD (High Dynamic) framing places it in the higher-accel end of the 1FK2 range, sized for short-stroke packaging, indexing tables, and small-format converting machinery rather than long-constant-load conveyor duty. Stall torque is 1.27 Nm with a rated point of 0.6 kW at nN=6000 rpm on a 380–480 V bus, and 0.4 kW at nN=3000 rpm on a 200–240 V bus — the same frame running on the lower-voltage SINAMICS S210 input chassis. The dual rating is the headline number to match when a retrofit swaps the upstream transformer or the panel migrates from 230 V to 400 V class. Feedback is an absolute encoder single-turn 22-bit, designated AS22DQC, with the OCC (One Cable Connection) interface routed through a rotatable M17 plug at the housing. OCC collapses the encoder and power conductors into one cable — the cabinet-side wiring drops to a single drag-chain-friendly cord and the connector orientation can be rotated to follow the cable exit direction during panel layout. Mechanical side: a D19 x 40 mm shaft with feather key, IP65 sealing on the housing. IP65 here means the motor body tolerates typical machine-room splash and casual washdown, but it does not cover hosed-down food-and-bev duty — for that, look at the IP67/IP67G siblings in the same 1FK2 family. The 40 mm shaft length and feather key are the standard coupling fit for this frame size. ## Configuration, packaging, and compliance paperwork Product class is C — manufactured to order, not returnable for credit. The order quantity unit is 1 piece, packed 1 piece per shipper at 452.00 x 250.00 x 267.00 mm. Plan cabinet receiving and unpacking around the single-piece pack; this is not a shelf-sip SKU. For import paperwork, the Group Code on this line is R220, Product Group 9021 — those are the Siemens-internal codes that show up on the packing slip and the commercial invoice. ## Lifecycle and the BOM decision Build-to-order means lead time is confirmed at the RFQ stage against the requested quantity; we do not publish a stock count or a same-day ship posture on this code. If the machine builder needs to compress the panel schedule, the lever is the order quantity and the configured options on the variant, not a desperation buy of the same MPN.","metaTitle":"Siemens 1FK2104-4AK01-1SA0 SIMOTICS S-1FK2 HD servo, 0.6 kW","metaDescription":"Siemens 1FK2104-4AK01-1SA0 SIMOTICS S-1FK2 HD servo motor, 0.6 kW at 6000 rpm, IP65, OCC interface, active production.
