The 1FK7044-7AF71-1KB0 peer shares the same 8.16 kg frame and 1FK7044 mechanical envelope, but the suffix changes the option block — encoder type, holding-brake fitment, and connector discipline — so the encoder and brake terminations on the SINAMICS drive side have to be checked against the axis commissioning profile before the 1UB5 is accepted as a same-form-factor replacement."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/1FK7044-7AF71-1UB5","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/1FK7044-7AF71-1UB5 when reusing this data.
