What the order code identifies
The 1FK7060-5AF71-1KB5 is a 1FK7 compact synchronous servo motor from Siemens, the brushless servo line sized for mid-range motion axes where high dynamic response and a compact footprint are the deciding factors. The 1FK7 family is the standard Siemens pairing for SINAMICS S110/S120 drive platforms; the motor is selected by torque constant, shaft type, and encoder option encoded in the order-code suffix.
