What this motor is, and why the lifecycle tag matters on a feed axis
The 1FK7060-2AF71-1SG2: Lifecycle is flagged EOL/HOT, which is the signal that drives the procurement decision before any encoder or winding spec does: the original channel is winding down, last-time-buy windows are short, and new-build allocations are typically out of reach. On a feed axis, that means either the spare cabinet gets stocked now or the machine retrofit path has to be re-engineered around a different 1FK7 frame.
Sizing the swap against other 1FK7 frames on the rack
On a panel that was originally specified around the 1FK7044-7AF71-1KB0, a swap to the 1FK7060-2AF71-1SG2 is not wiring-neutral — the shaft height, flange, and resolver/encoder code have to be matched against the SINAMICS S120 drive parameter set, and the holding brake option (if fitted) is part of the order code, not a field add.
Procurement posture for an EOL/HOT servo
With lifecycle EOL/HOT, the supply channel that still carries traceability paperwork is independent distribution — new-old-stock, factory-surplus, and de-installation lots are quoted against the RFQ, and the quantity available is lot-specific. There is no factory-direct allocation to point at; the RFQ is what confirms what is actually on hand and what trace documents (nameplate photos, original Siemens shipping records) the buyer can demand.
