1FK7 compact synchronous motor on an EOL clock
The 1FK7034-2AK74-1EB0: Sync to the nanosecond or don't bother — and that is exactly the motion-integrator question a 1FK7 motor on a coordinated line answers: the encoder feedback and commutation need to land inside the drive's process-data slice so a missed frame is a fault, not a hiccup. Pair the motor only with the drive and firmware revision Siemens qualified it against; a substitution inside the same family looks pin-compatible but can shift the controller-cycle tuning enough to break cyclic lockstep on a multi-axis machine.
Lifecycle is eol_hot — plan the replacement window
Lock the replacement decision to the BOM position number and the drive firmware revision before committing to a substitute, otherwise the cyclic-sync behaviour changes the moment the rotor windings differ.
Quoting and supply posture for a hot-EOL servo
Pricing and availability for 1FK7034-2AK74-1EB0 are confirmed at RFQ against the BOM quantity — there is no public stock figure, no immediacy claim, and no factory-direct channel at the eol_hot stage. Independent distribution with traceable Siemens-stock inventory is the realistic supply posture: specify the order code, the quantity, and the target ship date into the RFQ, and the quote returns with the actual market availability rather than a list price that no longer reflects the funnel.
