Part identity and 1FK7 positioning
The 1FK7022-5AK71-1HH5 is a Siemens 1FK7 compact synchronous servo motor, ordered under that full order code with no substitutions permitted at the BOM line. The 1FK7 family is the short-stack synchronous line used where high dynamic response and a small footprint are required — typical placements are feed axes on machine tools, small indexing tables, and packaging or converting lines where the motor is paired with a SINAMICS S120 drive module on a common DC bus.
