What the order code covers
The Siemens 1FK7022-5AK71-1TA0 is a member of the 1FK7 COMPACT family of synchronous servo motors — the compact framing in the product description signals a short-stack, low-inertia design aimed at high-dynamic positioning rather than continuous-torque conveyor duty, which is what most buyers pulling this code off a SINAMICS S120 drive BOM are after.
How it lands in the panel and on the machine
As a Siemens 1FK7 COMPACT synchronous servo, it pairs with a SINAMICS S120 drive module over the DRIVE-CLiQ feedback path — the encoder variant encoded in the -1TA0 suffix determines whether the drive auto-commission recognises the motor on first power-up or whether the parameters have to be loaded from the starter project.
