There is no good place to ask this so I thought here is as good as any. I have many years experience with Powtran VFD's and this is the first time I have had any sort of issue with one. I installed one on my drill press or rather NCArcher installed it and when the drill is started the internet in the house drops out. Turning on the VFD does present a problem only when the go switch is pressed on the control panel of the VFD and the drill starts. I can't remember if the problem was always there and we changed to the NBN somewhere around the time the VFD was installed, if I could remember what it was like on ADSL I might be able to blame the new modem...or not. Has anyone had the same problem or can suggest a fix. NCArcher has suggested a shielded supply cable from the VFD to the drill and I will do that when I get a chance but life has been a bit busy lately.
