Hi there, trying to work out what connection on my vfd is for the fault reset and fault if anyone can help please, I think I’m right in saying if I change the parameter I can use X3 for the vfd fault reset?
Could I use the Ta/tb/tc relay as fault nc?

It would be much more helpful if you post a link to the manual so we can see it all, not just clipped pages.

the manual is linked below the last picture Shawn, but here it is again. thanks https://drive.google.com/drive/folders/ ... mwNGLDXzhl

Got it, yes X3 input would be set to 8 and the onboard relay is already setup as "a/c drive fault" by default according to the manual.

Oh that’s great so I just use the TA/TB as the fault and common. Thanks

Yes, TA is the commom leg of the VFD relay and TB is the NC closed side it you want to set it up as NC for the fault.

Trying to set X3 to 8 and it says err every time I try

Are you sure you have the correct manual? This is just one of the issues you run into with the Chinese inverters. Can you reach out to where you bought it from?

I have eventually had a reply from the seller he said F0.17 to number 2 from the manual he supplies, does that make sense with X3 though?
