When you said you plugged it in, plugging and unplugging could cause this problem if that is how you are using it, VFD Drives don't like to be unplugged to disconnect the power, and should never be used this way

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?

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

Turning the power on and off to your VFD will not cause a problem. You should Never turn off the power going to the spindle motor when the VFD is powered up it will cause the VFD to fail. My guess the VFD is either programmed wrong or defective.

My drive is not Chinese maybe that makes a difference as it does not lose the programing.

It does not matter what VFD Drive it is they don't like being plugged in and unplugged and should never be installed like this

The problem is he is not turning the power off, he is unplugging it this by it's self is going to mess up the VFD or damage it, here is a snip from the VFD Drive manual
