I had a similar (but much less serious) problem and one of the things I did was to take the outgoing motor cables through a common-mode choke. (ie all three wires go through the same ferrite toroid a few times before continuing to the motor. The idea of this is that it slows the rise-rate of the VFD chopper pulses and removes some of the high-frequency content. I suspect it is not a good idea to over-do this. I also don't know it if helped, as I fitted an input filter at the same time. It is interesting that the Mesa 8i20s I have all came with a clamp-on toroid for the output wires supplied. (And the output toroid suggestion came from PCW) -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ One dashboard for servers and applications across Physical-Virtual-Cloud Widest out-of-the-box monitoring support with 50+ applications Performance metrics, stats and reports that give you Actionable Insights Deep dive visibility with transaction tracing using APM Insight. http://ad.doubleclick.net/ddm/clk/290420510;117567292;y _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
