You probably need an input filter on the VFD. They appear to send noise back down the power supply cables. Something like: http://www.ebay.co.uk/itm/170127787597 ("RASMI" may be a good search term) A common-mode ferrite ring on the motor cables (at the drive end) is also a good idea, but I think that the input filter is the big-hitter. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.
