Some higher end VFDs have line filters built in. Might want to check to see if yours does before you buy a filter. Dave On 11/1/2016 10:06 PM, Jon Elson wrote: > On 11/01/2016 07:33 AM, John Alexander Stewart wrote: >> Line Reactors. 10A. Generally a good idea or not really worth worrying >> a

Andy - that's a good point about "plug-in" equipment. The lathe with original motor does not have a fuse, nor does my larger plug-in lathe, nor my mill. All with capacitor start "2-phase" motors; either 120v or 240v. My 240v circuit is fused for 15A. I generally only run 1 machine at a time, so on

No, it is not overkill to fuse both (or all 3 with 3 phase) "hot" lines, it is code. - Original Message - From: "John Alexander Stewart" To: "Enhanced Machine Controller (EMC)" Sent: Tuesday, November 1, 2016 8:33:39 AM Subject: [Emc-users] Question rega

Hi all; Back to my CNC lathe project; it has sat dormant for a few years now. Opinions wanted: The VFD suggests 10a external fuses, plus a line filter. I'm running this on 240v, over here in North America. Are 10A slow blow 250v glass fuses ok for this application? Is it overkill to fuse both
