On a CNC retrofit or a 5-axis machining centre, a motor in this class is paired with a SINAMICS drive over PROFINET / EtherCAT and an absolute encoder on the shaft; the deterministic comms and clean feedback are what keep following error and following-error variance down run after run.","metaTitle":"Siemens 1FK7042-5AF71-1DG3 Servo Motor, EOL/HOT, 5.44 kg","metaDescription":"Siemens 1FK7042-5AF71-1DG3 1FK7 compact synchronous servo motor, listed at 5.44 kg.
