Variable Frequency Drive Noise Reduction
My Variable Frequency Drive (VFD) powers my mill's spindle motor. The mill is controlled by a Computer Numerical Control (CNC) system. As I used my mill in CNC mode, it quickly became evident that noise from the VFD was crashing the CNC. This article explains how I stopped the crashes and why the fix worked.
