Fagor Automation’s auto-tuning feature for PCs and CNCs automatically fine-tunes machine servo performance to maximize machine tool efficiency and performance. Developed as a tool that can be loaded directly to a Fagor 8065 or 8070 CNC or on a PC, the auto-tuning feature has the ability to carry out a fine servo-performance tune one axis at a time or on all axes automatically.
The program enables multi-machine tuning via an icon directory for each machine for fast, easy selection. The main tuning screen displays a graphic section, menu bar, icon bar, axes bar, command bar, parameter table, monitoring area, results area, data information for all active commands and a status bar to provide a single-page, simple layout for quick and easy access to any data with a single click. Users can execute the auto-tuning command from the command bar to execute the desired tuning procedure, and are able to limit adjustments to feedback, proportional gains, offsets, servo gains, or the velocity or position loop.
Users can start, stop, pause or continue even during the tuning procedure. Bode frequency response diagrams can be displayed within the graphics mode, enabling users to interpret the dynamic behavior of the axes and make decisions for later readjustments of the control loops. Measurements taken within the operating mode help to develop a more detailed display of the various diagrams. As many as four channels can be activated or modified on the scale shown.
The “result” label prompts a non-editable table which shows the parameter values of the auto-tuning procedure results. The table proposes changes for the results for the best performance, while the user retains full control of which parameters are changed. An information bar displays the cutoff frequency (BW), the gain margin (MG) or the phase margin (MF) of the bode diagram before and after the auto-tuning for final decision making.
