Avoid Common Mode Current Issues With Proper VFD Cable Grounding and Shielding
Machine designers who choose VFD cables for their motor-driven systems want to be sure their drive is reliable in order to take full advantage of the precision and energy savings VFDs can offer. Because VFDs produce unbalanced three-phase vector sums that give rise to various unwanted paths to earth, VFD cables must be shielded and properly grounded.
