Rated torque, speed, and what an EOL flag does to the BOM
The 1FK70635AF711UB3 is a 3-phase AC synchronous servo motor rated 11 Nm continuous torque at 2.29 kW and 3000 rpm, sized for the mid-inertia point of the SIMOTICS 1FK7 family that pairs with SINAMICS S120 drives on packaging, converting, and machine-tool axes. Its lifecycle stage is listed as eol_hot, meaning the part has crossed into Siemens' phase-out lane and is no longer flowing through normal production runs — a stock order against a fresh BOM line should be treated as a last-time-buy or independent-channel pull.
Storeroom angle — why an 11 Nm EOL slot is a different kind of spare
A 2.29 kW synchronous servo is not a commodity fuse or contactor — it lives in the drive cabinet, keyed to the SINAMICS firmware version that commissioned it, and it pulls a nameplate identity (Siemens) that any replacement must trace cleanly back through the order file. The eol_hot flag is the cue to lock down the lot before the line goes down: cross out the slot on the storeroom pick-list, capture the serial range already on the shelf, and price the same code against an RFQ rather than waiting for a next-quarter stocking cycle.
