Using Notch Filters to Mitigate Resonance

Learn how to implement notch filters to control mechanical resonances that can destabilize motion control systems. This guide covers resonance fundamentals, filter placement strategies, and practical configuration using Galil DMC controller commands. Includes real-world examples for both high and low frequency resonance scenarios with step-by-step implementation techniques.
