The 1FK7 high-dynamic frame on a machine bed
The Siemens 1FK7061-4CF71-1CG0 is a 1FK7 high-dynamic synchronous servo motor — the compact, high-acceleration frame Siemens builds into packaging, converting, and pick-and-place machinery where the drive has to accelerate and reverse a load faster than a standard asynchronous servo can manage. It pairs to a SINAMICS-class drive in the same way the rest of the 1FK7 family does, so the commissioning profile (encoder resolution, resolver, DRIVE-CLiQ wiring) follows the standard 1FK7 commissioning map rather than a one-off variant.
Lifecycle read: EOL_HOT and what it means for the BOM
An EOL_HOT motor still ships as a factory-sealed unit, but the planning horizon is the controlling number — if a machine is going into a new line that will run for ten years, the procurement question is not the price of the motor today but whether a supported successor in the 1FK7 family or the current Siemens servo platform can be qualified before the last lot dries up.
