The motor and why the lifecycle flag runs this page
The 1FK70425AF711SA0 is a SIMOTICS S-1FK7 synchronous servo in the short-stack 1FK7 frame — a compact motor typically paired with a SINAMICS S120 drive and run on the inertia-matched load classes that 1FK7 is specified for. The part designation breaks down to a 1FK7042 frame with a keyway shaft and resolver feedback, which is the build most installers know on legacy machine spindles and indexing axes where the resolver interface is already wired into the cabinet.
