EOL compact synchronous motor on the bench
The 1FK7060-5AF71-1GB0: Compact synchronous servos in this class typically pair with a SINAMICS S120 drive on a PROFINET or PROFIdrive motion bus, so any spare on the shelf is sized for a swap-in on an existing axis rather than a new commissioning.
Why the 8.16 kg rotor matters for inertia matching
The compact synchronous design is built for high dynamic response on short-stroke axes (packaging, indexing tables, small gantries) where the loop bandwidth, not continuous torque, is the constraint.
Sourcing posture for an EOL Siemens servo
With the lifecycle stage recorded as EOL, the part is not on a standard Siemens quotation and the supply path runs through independent distribution with lot-specific availability — every quote is conditioned on what surplus stock or factory-reman channels hold at the time the RFQ lands. For a line-down spare, the practical question is whether a same-frame sibling from the 1FK7 family (different winding or brake option) can be re-parameterised in the drive project — that decision needs the nameplate data of the installed unit and the current SINAMICS firmware topology, neither of which the part-number string alone resolves.
