Product details

1FK7043-7AH71-1FH3 — what the line sticker says

The 1FK7043-7AH71-1FH3 is a Siemens 1FK7 high-dynamic synchronous servo motor — a compact brushless servomotor that pairs with a SINAMICS S120 drive module and resolves position via a built-in absolute encoder for high-throughput motion on packaging, converting, and machine-tool axes.

Lifecycle — EOL/hot-runoff, what that buys you

Lifecycle stage is recorded as EOL/hot-runoff: Siemens has formally retired the part from the active catalog but continues to honor manufacturing and supply under the legacy/PCN framework until a final stop date, so the BOM line still closes through the OEM channel — and independent distributors carry surplus stock of sealed, traceable units for replacement spares. There is no official L* successor listed for this order code in the record: a panel specified around the 1FK7042-5AF71-1DB0 is the same 1FK7 family but a different shaft/winding/encoder option, so drop-in replacement requires confirming the encoder protocol (resolver vs. multi-turn absolute), brake option, and connector keying against the BOM, not just the frame size.

Sourcing posture for an EOL/hot-runoff servo motor

For a 1FK7043-7AH71-1FH3 BOM line under EOL/hot-runoff, the practical sourcing lane is independent distribution carrying sealed, date-coded Siemens stock — quoted against the RFQ quantity with full traceability paperwork (decl-of-conformance and nameplate trace) confirmed per lot at quote time.

Frequently asked questions

Will 1FK7043-7AH71-1FH3 drop into a panel that was specified around 1FK7042-5AF71-1DB0 without rewiring?

No — the 1FK7042-5AF71-1DB0 is a different 1FK7 winding/encoder option at 5.44 kg, so shaft key, brake, and encoder protocol have to be reconciled against the BOM before any swap. Same family does not mean same drive configuration.
