What this motor is
The 1FK7080-5AF71-1SG0 is a Siemens synchronous servo motor from the SIMOTICS S-class 1FK7 family, used in motion-control axes driven by SINAMICS S120 and similar SINUMERIK/SIMOTION inverters.
Lifecycle status — what EOL means for a BOM line
Siemens issued this code with a descriptor dated 01.10.2019, consistent with a final-orderable revision on the 1FK7 line before migration to the successor SIMOTICS S-1FK2 platform.
Ordering posture for this exact code
Buyers running a line-down spare or a maintenance cap for an existing 1FK7080-5AF71-1SG0 axis should treat the part as a confirmed-fit EOL pull rather than a re-design trigger: the encoder wiring, resolver/absolute encoder interface, and shaft key remain standard for the 1FK7 frame, so a like-for-like swap stays inside the original panel footprint.
