8.16 kg on a frame 6 — what the motor physically is
The 1FK7060-5AH71-1DB3: The part slots into a SIMOTICS S-type control loop — that is the synchronous-servo family designed to run behind a SINAMICS S120 drive module on machine-tool and high-dynamic positioning axes. For commissioning the motor pairs with the drive firmware profile that matches the 1FK7060 frame; mismatched motor-ID data on first power-up is the usual reason a like-for-like replacement faults out before it spins.
