On the panel side the motor interfaces to a Siemens SINAMICS drive (typically S110 or S120) over the DRIVE-CLiQ feedback path that the 1FK7 encoder carries internally — encoder and resolver variants in the order-code tail determine which drive controller family auto-commission the motor without manual parameter entry. ## Lifecycle read — what eol_hot actually means for the BOM line The order code carries an EOL hot-stage designation, meaning last-time-buy notices have been issued and the remaining production window is constrained — a spare-parts replenishment order placed today may not be repeatable from the factory twelve months out, so the BOM decision is whether to cover the full service-life requirement now or accept the independent-channel risk later. With no official L-record successor published alongside the EOL hot-stage marker on this order code, the documented second-source path is not on the record from Siemens — any cross-reference has to be qualified parametrically against the replacement 1FK7 frame or the 1FK8 successor family, not assumed pin-compatible. For an installation already running SINAMICS firmware the field-replacement path that does NOT require a firmware or wiring change is to source against the same 1FK7033-4CK71-1TG0 code through independent distribution — quotes are returned with lot traceability and conformity documentation so the spare can be accepted against the same engineering baseline. ## Physical handling — 3.18 kg in the cabinet and on the shaft Because the encoder and resolver signals are sensitive to cable routing, the feedback cable alongside the power cable needs a screened run with the screen bonded at the drive-end gland — skipping the screen termination is the single most common commissioning fault on this class of axis and shows up as following-error faults under dynamic moves. ## Compliance paperwork the buyer should expect with the shipment For a 1FK7-class servo motor the conformity dossier normally accompanies the shipment as a Siemens declaration of conformity covering the Low Voltage Directive and the relevant EMC standard for the drive system as installed — a CE-marked motor in this class is also typically backed by a manufacturer's RoHS and REACH statement covering the materials in the housing, encoder PCB and stator insulation system. Independent-channel sourcing does not weaken that documentation chain — the declaration of conformity and the material-compliance statements travel with the serial-numbered unit, and the buyer's supplier-quality sign-off should accept them against the same audit evidence that an OEM-direct shipment would carry, provided the lot traceability is intact.","metaTitle":"Siemens 1FK7033-4CK71-1TG0 Servo Motor, EOL phase-out","metaDescription":"Siemens 1FK7033-4CK71-1TG0 1FK7 high-dynamic synchronous servo motor, 3.18 kg, flagged EOL — quoted to order against an RFQ with traceability confirmed at","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Servo Motors"],"specifications":{"title":"1FK7033-4CK71-1TG0","Part #":"1FK7033-4CK71-1TG0","Weight":"3.18 kgs","Category":"Motors","description":"1FK7033-4CK71-1TG0 - 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":"$961.17","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/f6af291cfbca0666aeba3fe9ec3cf866.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What compliance documentation does Siemens provide for 1FK7033-4CK71-1TG0?","answer":"Shipments of the 1FK7033-4CK71-1TG0 through independent channels carry the Siemens declaration of conformity for the relevant EU directives together with the manufacturer's RoHS and REACH material statements — the supplier-quality dossier should be reviewed against the same audit checklist an OEM-direct shipment would satisfy, provided the lot traceability is intact."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/1FK7033-4CK71-1TG0","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/1FK7033-4CK71-1TG0 when reusing this data.
