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
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.
Pd001 - 2
Pd002 - 2
Pd163 - 1
Pd164 - 1
Pd165 - 3

Ok.

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

loadusr -Wn spindle-vfd hy_vfd -n spindle-vfd -t 1 -d /dev/ttyUSB0 -p none -r 9600 -s 1 -g

 

halcmd: loadusr -Wn spindle-vfd hy_vfd -n spindle-vfd -t 1 -d /dev/ttyUSB0 -p none -r 9600 -s 1 -g
spindle-vfd: device='/dev/ttyUSB0', baud=9600, bits=8, parity='none', stopbits=1, address=1, debug=1, PID=4356
Opening /dev/ttyUSB0 at 9600 bauds (none)

then setp spindle-vfd.enable 1

and:

ERROR Communication time out (-12)

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.

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