Both share the 1FK7042 frame, but 1FK7042-5AF21-1UA0 is listed at 4.54 kg versus 2.57 kg here — the rotor mass change shifts inertia, coupling sizing and drive-side tuning parameters, so a straight panel swap will not behave the same."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/1FK7042-5AF71-1AH3","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/1FK7042-5AF71-1AH3 when reusing this data.
