huanyang vfd won't communicate get errors.

I have tried just setting the enable via HAL command: I get the error shown below. Does anyone have any idea what the error code means. I can see the communications happening on an o scope. It looks like HAL keeps trying to communicate as it never stops.

It looks like HAL keeps trying to communicate as it never stops.
I think that is expected behaviour.
However, there seems to be no data coming back from the VFD.
What model of VFD is it? There was a mention on the mailing list back in february:
"2. The LinuxCNC Huanyang driver only works with the older style of
Huanyang VFDs. It does not work with the newer GT-series models. I'm
working on a new driver for Huanyang GT VFDs, but it's not ready yet."

I'v had this 1.5KW VFD for 6 or 7 years (can't read the label where the VFD is in the panel). I was using it with an external pot till now and allowing Linuxcnc to start it from the M3.
I have tried 2 different (third on order) rs485 converters. The cheap USB model has the cleanest signals. With the RS232 version I have seen data I believe is from the vfd but if it is it is not the data hy_vfd wants. When I start linuxcnc I can see the data on the Oscope linuxcnc keeps sending some packet. With the RS232 converter I see what looks like more data and the receive led on my serial monitor flashes. (might be noise). I tried a serial sniffer program and it looked like the VFD was returning FF F7 each time linuxcnc sent whatever it was sending.
Thanks

halcmd: loadusr -Wn spindle-vfd hy_vfd -n spindle-vfd -t 1 -d /dev/ttyS0 -p none -r 19200 -s 1
When I got my huanyang vfd going I could not use the stop bit's or parity in the connection string.
Also make sure you have the + going to the + from the adapter to the vfd. As I'm sure you know; you have to use usb instead of ttyS0 if using a USB-serial adapter.
Try different baud rates with different parity settings. When you keep getting the time out you know its not communicating.
when issuing the command in a terminal
lsusb
I get the output of:

What do you get? You may need to install usbtools I believe it is called for the lsusb to work. Let me know if you run into a snag.

loadusr -W hy_vfd -d /dev/ttyUSB0
Why not try that?
(Addendum) I tried your loadusr line and it worked, _Except_ I had to set -d to ttyUSB0 not ttyS0.

Tried getting rid of -p did not use stop bits. When parity is removed it appears that hy_vfd defaults to even parity. I tried all three combinations the same result. The data that hy_vfd is sending over and over appears to be
0x01 0x01 0x0B 0x2c 0x30 or decimal 01 01 13 44 48. Thanks

What are your settings in the VFD for that string?
mine:
163 = 1
164 = 2
165 = 3
The same, I think. I just set the VFD to the hy_vfd component defaults, and then load the component without extra options.
I did add a separate gnd/shield to my USB dongle:
forum.linuxcnc.org/forum/18-computer/306...485-connection#72351
(looking now, I didn't show it with the extra wire + screw terminal in that post, but it now has a 3-screw terminal block)
I used Van Damme DMX 1-pair + shield for the connection. But largely only because it was available in purple
