The 1FK7042-5AF71-1EH3 is the compact synchronous servo from the Siemens 1FK7 family — a brushless AC servo sized for high-dynamic positioning axes such as feed drives, small-format indexing tables, and packaging or pick-and-place modules where the 1FK7 frame typically mounts up against a SINAMICS S120 or S210 drive.
Both are documented at 5.44 kg in the same frame, so the mechanical fit looks preserved. The winding code, brake option, and encoder type still differ by suffix and need to be cross-checked against the panel drawing — do not assume electrical interchange without confirming those three fields.
Alternative models and sibling configurations in the same Siemens series. For obsolete or discontinued parts, these models can serve as compatible replacements or functional alternatives for plant maintenance.
