Setting up a Haunyang VFD

[Desertboy]

That's not a good sign, it's suggesting the spindle is going to ground. Does it make any buzzing sounds then trips or instantly trips.? Does the spindle twitch at all.?

Silly question but you have checked the spindle isn't seized or the cable damaged.? It's often the silly things that bite you.!

The cable is brand new but I'll check it just in case, the spindle is also brand new could the vfd be at fault? With the old spindle as soon as I pressed run it blew fuses in the 13amp plug the machine is on. The VFD powered on fine with the spindle unplugged counted up to 400 so I assumed the spindle failed

It worked fine but I left it for 6 months other stuff came up and when I came back this started

I only have 1, 2 & 3 pins soldered on as the spindle isn't earthed I was going to do that after I get it working I have checked continuity from the spindle plug to the VFD it seems good no shorts I have grounded the RF wiring

The VFD to spindle cable length is ~5m one solid piece

Have you tried testing without spindle connected this time.?

Also, did you put heat shrink or tape over the soldered pins, if not they could be touching the connector body, though I'd expect an earth leakage trip before the VFD error?

Check if you have continuity between the pins and the spindle body, you shouldn't have any.

I have continuity between pins 1, 2 & 3 but not 4

There is no continuity between 1,2 & 3 and the body

There is continuity between pin 4 and the body (So it's grounded from factory correct?) I was surprised I just assumed it wasn't because they never are

I will solder pin 4 on, which will mean removing the 3 I soldered to get everything the right length again I removed the earth was going to send a separate wire and earth the spindle holder instead.

Since I did a factory reset on the Haunyang it does nothing when I press run but I can access the setting menu

I do have another Chinese VFD I can swap in correct rating an AT1-2200X never been used

What I don't want to do is damage the new spindle
