Tuning a Piezomotor DMC-30019 and LEGS Piezoelectric Motor for High Resolution Motion Control

Learn how to achieve nanometer-level positioning accuracy using Galil's DMC-30019 controller with LEGS piezoelectric motors. This application note demonstrates tuning methods for overcoming the non-linear characteristics of piezoelectric motors, showcasing step-and-settle performance within ±5 counts (25nm) and dynamic following error of ±35 counts (175nm) during motion. Includes hardware setup, tuning procedures using GDK scope tools, and performance data for both loaded and unloaded conditions.
