Cell fit and where this motor lands
The 1FK7034-5AK71-1DA5 is a 1FK7 high-dynamic synchronous servo motor from Siemens — the compact, high-acceleration end of the 1FK7 family typically specified on short-cycle motion axes where the cell budget hinges on torque-to-inertia and rapid dynamic response. On a robot cell or indexing conveyor the motor sits behind a SINAMICS S120 drive on a DRIVE-CLiQ or resolver feedback loop; the high-dynamic winding is chosen specifically because the axis needs to accelerate and reverse inside a short cycle window, so the drive commissioning has to close that cycle budget rather than rely on inertia reserves.
