For a category strategy view, an eol_hot flag on a Siemens 1FK7 synchronous servo concentrates spend under management onto a shrinking supplier pool — the lever now is allocation of known-good surplus against the install base, not volume re-buys at the OEM price book. ## Mechanical envelope and panel-side handling Servo motors in this class are paired with a SINAMICS drive on the same DC-bus family; the encoder feedback, holding brake option and shaft keying live inside the 1FK7 order code, so a replacement motor must match the original suffix string to drop onto the existing commissioning map without re-parameterising the drive.","metaTitle":"Siemens 1FK7043-4CF21-1RG0 Servo Motor, 5.90 kg, EOL","metaDescription":"Siemens 1FK7043-4CF21-1RG0 1FK7 high-dynamic synchronous servo motor, 5.90 kg, flagged EOL/hot.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Servo Motors"],"specifications":{"title":"1FK7043-4CF21-1RG0","Part #":"1FK7043-4CF21-1RG0","Weight":"5.90 kgs","Category":"Motors","description":"1FK7043-4CF21-1RG0 - 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":"$906.78","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/647530720402e9bdb23d5fbad456dc20.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 1FK7043-4CF21-1RG0 and how do I get a price?","answer":"The motor is sourced to order through independent distribution — submit the BOM line as an RFQ with the quantity, the encoder suffix and any holding-brake variant, and current availability plus pricing is confirmed at quote time against the surplus lot on hand."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/1FK7043-4CF21-1RG0","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/1FK7043-4CF21-1RG0 when reusing this data.
