And you are sure you are using this to load the component:
loadusr -Wn spindle-vfd hy_vfd -n spindle-vfd -t 1 -d /dev/ttyUSB0 -p none -r 9600 -s 1

[/code]loadusr -Wn spindle-vfd hy_vfd -n spindle-vfd -t 1 -d /dev/ttyUSB0 -p none -r 9600 -s 1 So, I do this: sudo chmod 666 /dev/ttyUSB0 halrun [code]loadusr -Wn spindle-vfd hy_vfd -n spindle-vfd -t 1 -d /dev/ttyUSB0 -p none -r 9600 -s 1 setp spindle-vfd.enable 1 and it gives me same error: error reading setup from VFD And yes, my hy vfd is set to these settings.

Ok.
Have you tried adding the debug option to the loadusr command?

The next thing I'd be replacing was the wiring between the RS485 adaptor and the vfd using shielded cable connecting the shield to ground on the vfd or computer or possibly both.
But it's really difficult to troubleshoot this from afar.
Anyway I have run out of time for today. I'm sorry we have not found a solution for this.

I dont think wiring is a problem here, I use simple wires, 30 cm long. It works on windows, mach3 as well.

Late to the party here, but:
Which model of HY VFD are you using? There are two possible HY drivers:
linuxcnc.org/docs/2.8/html/man/man1/hy_vfd.1.html
linuxcnc.org/docs/2.8/html/man/man1/hy_gt_vfd.1.html
If it all works with Windows then we can probably discount hardware as the cause, but I use one of these and it does have the advantage of being rather neater as an installation:
www.amazon.co.uk/gp/product/B082KKG55T
(I cut off the crocodile clips)
Are you _sure_ it isn't working? It is easy to forget to set the hy_vfd.enable pin to 1, and if you don't do that then it won't work.
I get some spurious error messages even with a working system.
