Is this 1FK7 still being built today?
Siemens 1FK7044-4CH71-1RG0 is the high-dynamic 1FK7 synchronous servo motor, and the line carries an EOL/HOT lifecycle flag — meaning the catalogue record is on the hot list for last-time-buy rather than ongoing production. For a controls desk that already standardises on 1FK7 feedback, holding spares against this code is a different conversation than nominating it on a new machine — get the buy-in for whatever the replacement frame is before committing the BOM line.
Sourcing posture for a hot-flagged servo
On an EOL/HOT record the practical sourcing path is independent distribution quoting against the BOM — availability and pricing are confirmed at RFQ, not advertised, because the remaining stock is lot-specific and the OEM has signalled last-time-buy territory. For a line where a 1FK7 is already wired and parameterised, the cleanest move is to lock remaining stock while the channel still has it; for a greenfield machine, validate the successor frame with Siemens before specifying — no official replacement order code is carried on this record.
