The 1FK7 high-dynamic line is the compact, high-acceleration tier of Siemens synchronous servos — typically paired with SINAMICS S120 drive line-ups for high-throughput indexing, packaging, and feed axes where the rotor's low inertia pays back in short cycle times. For a line that already runs on this motor, the practical question is whether to spec a phased last-time-buy or migrate the axis to the current 1FK7 / SIMOTICS generation — a board-level migration that has to be evaluated against drive firmware compatibility, encoder type, and mechanical fitment, none of which are confirmed in this record. ## How it sits next to its 1FK7 siblings Drop-in compatibility between these order codes is not confirmed by the evidence — the order-code suffix carries the encoder, shaft, holding-brake, and connector options, and a like-for-like swap requires those suffixes to align, not just the frame size.","metaTitle":"Siemens 1FK7044-4CF71-1QB0 Servo Motor, EOL, 7.71 kgs","metaDescription":"Siemens 1FK7044-4CF71-1QB0 1FK7 high-dynamic synchronous servo motor, 7.71 kgs, lifecycle eol_hot.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Servo Motors"],"specifications":{"title":"1FK7044-4CF71-1QB0","Part #":"1FK7044-4CF71-1QB0","Weight":"7.71 kgs","Category":"Motors","description":"1FK7044-4CF71-1QB0 - 1FK7 HIGH DYNAMIC SYNCHRONOUS MOTOR by SIEMENS","Sub Category":"Servo Motors","Top Category":"Motors & Motor Controls","lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$928.37","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/647530720402e9bdb23d5fbad456dc20.pdf","sourceUrl":null},"ai":{"faq":[{"question":"When sourcing 1FK7044-4CF71-1QB0, what is the closest functional second-source to 1FK7042-5AF71-1DB0?","answer":"The evidence does not confirm a like-for-like cross — the two order codes share the 1FK7 family and Servo Motors category but carry different weights (7.71 kgs vs 5.44 kgs) and different order-code suffixes, so encoder, brake, shaft, and connector variants must be verified against the nameplate before any swap is committed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/1FK7044-4CF71-1QB0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/1FK7044-4CF71-1QB0 when reusing this data.
