What it is and where it bolts in
The 1FK70805AH711DG0 is a Siemens SIMOTICS S-1FK7 synchronous servo motor in the Servo Motors category, built to mate with a SINAMICS drive on a standard feedback and power cable set. The order code is the canonical Siemens part identifier used across the 1FK7 line for factory-traceable stocking and field replacement. Listings carry this code under the Siemens brand with no functional expansion in the spec bundle beyond the catalog identity, so panel-side fit is decided by the drive pairing, the shaft and brake options encoded in the order code, and the resolver or encoder feedback variant — the dimensional and winding data lives on the official Siemens datasheet.
Lifecycle read and sourcing reality
The ledger records as eol_hot for 1FK70805AH711DG0, which means the part is on a phase-out or last-buy track from Siemens and the new-build channel through the OEM is closing. No official successor is carried on the ledger for this order code, so a board-spin replacement cannot be asserted from this record. Where a buyer needs a drop-in, the supported path is to cross the 1FK7 order-code suffix to a current-build variant with Siemens support or quote the same code through the surplus channel — quoted against the BOM quantity, not promised from stock.
