[QUOTE=FGS;2293108]I'm still having problems. It seems if I haven't used my CNC for a while the VFD loses the settings. So I'll reprogram it and see if that's the problem. I'm not sure what you mean by you shouldn't unplug and plug the VFD. Mine is wired into my control box and comes on when I turn on my control box, but how is that different than pulling the plug and switching it on and off?[/QUOTE]

You need to post a photo of how you have it wired it does not sound like it has been done correctly when you put the Parameters in you can lock them in PD000=0 this will lock them in if your drive is not damaged
