1FK7 high-dynamic servo motor, Siemens order code 1FK7044-7AF71-1GG0
1FK7 compact servos pair with the SINAMICS S120 drive line and the SIMOTION / SIMATIC motion controller family on the fieldbus side, so the motor drops into high-dynamic point-to-point and continuous-path motion axes where the machine builder has already standardised on Siemens motion hardware.
7.26 kg rotor in the cabinet — handling and panel fit
On the panel side, mount the servo to a flat machined surface with the coupling alignment checked before energising the drive, and confirm the encoder connector variant against the SINAMICS drive firmware version — the wrong encoder type is the most common commissioning fault on a replaced 1FK7 motor.
