Product details

Where this 1FK7 fits on the machine

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.

Frequently asked questions

Will 1FK7042-5AF71-1EH3 drop into a panel that was specified around 1FK7042-5AF71-1DB0 without rewiring?

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.
