What the EOL flag means when you arrive at this order code
The 1FK7042-5AF21-1UG0: The part lands on the desk with flagged eol_hot, so the BOM line is being filled against a motor the factory has wound down rather than a current catalog number — order intake runs through the independent distribution channel and lot-specific availability is confirmed at quote time.
Where a 1FK7 compact synchronous servo gets specified
A 1FK7-frame motor like this one sits at the back of a closed servo loop on a feed or auxiliary axis, paired with a SINAMICS drive and a high-resolution encoder — the deterministic comms to the drive is what keeps following error flat under acceleration.
Filling the BOM line under an EOL servo motor
Because the order code is flagged EOL, procurement needs to treat each RFQ as a lot-driven inquiry — matched surplus and factory-traceable stock are quoted against the request, and any cross to a still-active 1FK7 variant is confirmed against the drive-side parameter list before the line is committed.
