At 100 K winding class and a compact short-stack frame, this slot typically drives a small positioning axis — feed-roll, cross-seal, indexing table, or a light conveyor section on a packaging or converting line — driven from a SINAMICS S120 or similar modular drive set. ## Lifecycle read: spare-part stock, not a new build The ordering code carries eol_hot — meaning Siemens has moved the 1FK7040-5AK71-1 out of normal catalog stocking, with remaining material released as spare-part inventory rather than as a current-production configuration. Quotations are lot-specific — quantities, condition (new-surplus vs refurb), and traceability are confirmed at RFQ time against current independent-channel stock. ## Fit envelope a buyer has to clear The shaft envelope — 1.6 Nm holding torque class and 6000 rpm speed ceiling — sets the mechanical sizing: this is not the motor for a high-inertia roll or a heavy spindle, but it is the right class for a light-servo axis where compact frame length and clean dynamic response matter more than absolute torque density. The rotatable power/signal plug is the practical install point: the same motor can be rotated in its mounting to keep the cable exit on the cable-tray side of the cabinet, which matters when the drive is in a back-plane cut-out with limited vertical clearance above the motor.","metaTitle":"1FK7040-5AK71-1...
