What the motor is and what it sits on
The 1FK7044-4CF74-1SB2: The 1FK7 family is the high-dynamic servo line — its role in the panel is to drive the precision axis (feed, rotary table, indexing, packaging) through a matching Siemens drive, with the resolver or absolute encoder wired back to close the velocity and position loops.
Lifecycle status and what it means for the BOM line
For a panel or machine that was originally specified around this exact 1FK7044-4CF74-1SB2, the procurement move is to secure the quantity required for the full machine lifecycle (spares plus last builds) while the eol-hot inventory still flows, rather than waiting for a second-source swap.
Sourcing posture for an eol-hot servo
Quoted to order through independent distribution against an RFQ: each request returns the available lot quantity, the unit traceability paperwork, and the current price band at quote time — no standing-stock claim and no immediacy promise. Lead time on this class of eol-hot Siemens servo is governed by the inventory position of the specific lot on hand when the RFQ lands, not by a factory schedule — pricing and availability are confirmed only at the quote step.
