What 1FK7063-5AF71-1SH3 is on the bill of materials
The 1FK7063-5AF71-1SH3 is a Siemens synchronous servo motor from the 1FK7 family, the compact-drive motor line paired with SINAMICS S120 and similar drive controllers on positioning and feed axes. On a commissioning bench, what the integrator needs to verify first is that the nameplate code — shaft length, encoder, and brake options embedded in the suffix — matches the drive configuration and the mechanical side of the machine; the wrong suffix on this family typically means a mismatched holding brake or feedback type rather than a different frame size.
