The 1FK7080-5AH71-1KG0: 1FK7 compact motors are the encoder-equipped, permanent-magnet synchronous machines Siemens ships into machine-tool feed axes, packaging lines, and converting-web drives where torque density and dynamic response matter more than the absolute stall torque of a 1FT7 equivalent.
Lifecycle status and what that means for the BOM
The flag is eol_hot, meaning Siemens has moved this order code into the active phase-out window: production is winding down but the part is still orderable from the factory today, and last-time-buy terms typically apply for late-stage orders. For a maintenance spare that needs to ride the machine for the next ten years, the eol_hot read is the green light to put one on the shelf as a verified drop-in replacement; for a new machine build, the conversation shifts to confirming whether the axis controller firmware revision still recognises this motor on first commissioning.
