Where the 1FK7034-5AK71-1LA3 sits in a motion axis
Siemens 1FK7034-5AK71-1LA3 is a 1FK7 high-dynamic synchronous servo motor — the compact, high-acceleration end of the SIMOTICS S line, sized for short-cycle machines where the velocity loop has to close fast and the inertia match runs close to unity.
Lifecycle flag and what it means for the BOM
The listing carries eol_hot — the part is past its last-time-buy window on the Siemens new-channel roster, so new-build designs are expected to migrate to the active 1FK7 successor variant while installed fleets source through independent channels.
Procurement posture for an EOL servo
Quoted to order against the BOM through independent distribution — availability, current pricing, and the OEM-traceable documentation pack are confirmed at RFQ rather than at the shelf, because EOL stock is lot-specific and tied to the channel that last booked it.
