it is possible that it is working, but with occasional timeouts.

If you "show pin" again after the VFD is enabled do you see any data?
(Such as DC bus voltage)

you mean in the live HAL session ? the text does not stop scrolling.
So I guess I must try in LinuxCNC right ?

You can type "through" the scrolling messages.

Or, before enabling the component:

loadusr halmeter

and pick a vfd pin. (you can repeat the command to get several halmeters)

Ok then I've selected the pin hy_vfd.enable which is FALSE
when I type the command hy_vfd.enable 1 this becomes TRUE

no message related to DC bus voltage

hy_vfd.DCV stays at 0 after typing hy_vfd.enable 1 wile hy_vfd.enable switches from FALSE to TRUE

.enable is sent to the VFD from HAL, so that just shows what you are setting it to.
If ACV and DCV both show as zero, and the VFD is powered up then that rather shows that there is no data transfer taking place.
(Which is what we suspected)

You have communicated to the VFD with other software, I believe? Does that still work with the current VFD settings? Does that allow you to confirm the bits. parity and stop bit setting which work with the VFD?

I just found out with the other software that I could only get the VFD to work at 9600 baud.
I tried varying the baud rates from 9600, then 19200 and finally 34800 (VFD [PD164] and software) and the communication with the port is only effective at 9600.

The values I can read on the other software are as follows:
baud rate: 9600
data bit: 8
parity: none
stop bit: 1 (I have the following choice: none, one , two, OnePointFi (?)
Modbus ID: 1

Google found this:

I had a problem with communications between the Huanyang 2.2 KW inverter and the Mach 3, I discovered that there had to be a connection between DCM (digital common) on the inverter and the PC, once that was established everything worked as it should. Although communications work on 2 wire, the reference point is apparently the common ground.

I carefully read what you had found about the DCM connection between the VFD and the PC.
I don't understand what I should test, I used the online translation to make sure I didn't miss anything but I must have burnt out neurons: I don't understand. Should I bridge the DCM terminal of the VFD with the GND (earth)?

I've tried so many things and manipulated so many parameters without really knowing what I was doing that I've just spent the morning in the garage to start from scratch and follow the procedures you recommended from the beginning again without success.
