Listed part number reads 1FK7034-5AK71-1LG3 in the Siemens order-code format (the row carries that exact dash-form), so cross-references on the BOM, the drive project file, and any PCN letter line up against the same string the seller keys to. ## Sourcing posture — EOL_hot, not a dead end Lifecycle is flagged as EOL_hot — the original factory run has wound down and the part now moves through independent channels rather than the standard Siemens direct line. With the EOL gate open, the practical move is a quoted-to-order RFQ: buyer confirms quantity and the desk pulls verified, traceable stock from lot-based inventory, with availability and current pricing aligned to that RFQ rather than a posted ticker; no figure, count, or immediacy claim is asserted here. ## Mechanical envelope and integration The 1FK7 frame pairs with a matching Siemens drive controller; the connector pattern, resolver/encoder feedback variant, and shaft key are dictated by the trailing order-code digits (the -1LG3 suffix), so the swap-in replacement has to match exactly on those digits — not just the family designation. ## Fit and a sourcing note for the spares shelf For an MRO planner chasing a hot spare for a downstream axis (a conveyor, a cross-feed, a labelling or pick-and-place station), the headline value is that 6000 rpm top speed and 1.6 Nm torque class — that's the envelope a replacement has to sit inside; dropping in a lower-rated servo risks tripping the drive's torque or speed limit on a peak cycle.","metaTitle":"Siemens 1FK70345AK711LG3 Servo Motor, 0.63 kW, 1.6 Nm","metaDescription":"Siemens 1FK70345AK711LG3 synchronous servo motor, 1.6 Nm / 0.63 kW / 6000 rpm.
