I have been looking everywhere for this information with no luck.
The vfd says that it is a Huanyang vfd but it is in fact an Isacon which has the same configuration as the askpower vfd's out there.
The manual is not much help so I'm hoping someone else is using one of these and can hopefully point me in the correct direction.
I am trying to run a water cooled spindle 400hz 2.2KW with the 2.2kw 3hp VFD. I have an ST-V2 breakout board and I also have a RS-485 to usb adapter. I have tried without success to connect the vfd to the breakout board using the 0-10v connections and the spindle relay. Not sure on how to write the custom.hal file for that scenario.
I have also tried to connect via the RS-485 usb connection and I am not sure which terminals on the vfd should be connected.
There seems to be good information on what to do with the custom.hal file for that scenario.
The terminal page is attached.
The VFD and Spindle work as they should in manual mode. But I want to be able to control the spindle through Linuxcnc.
I'm sure my inexperience is most of the problem . Any and all help would be greatly appreciated.

It doesn't appear that the VFD works with Modbus, so I think you will have to use 0-10V
Do you have a 0-10V variable voltage coming out of the break-out board?

Hi Andy,
Thank you for the speedy reply. Yes the ST-V2 Bob has 0-10v power supply which i believe controls the speed of the spindle. I will check the output voltage this afternoon to make sure it is correct.
Correct me if I'm wrong but I'm under the impression that I have to use a relay for Off/On also?
I am not sure what to put in the custom.hal file with this set up.

That will depend on the putput driver of your BoB. Some will work directly.

OK, I do have voltage coming out of the 0-10v output on the ST-V2 board. It measures .09v with nothing running.
I think my problem is with the custom.hal configuration. That is the last line Linuxcnc reads before shutting down: ./custom.hal found then shutting down. Not sure what to do. Please let me know what additional info I can post to help solve the problem

Is the problem that LinuxCNC does not control the spindle, or that LinuxCNC doesn't even run?
I thought it was the former, but your last message suggests the latter.
If LinuxCNC quits you can press the "selct all" button on the dialog, then Ctrl-C to copy it all, then paste it into a message here.

Somewhere you have a "setp pin value" with the pin or the value missing.
Welll, actually in custom.hal line 9.

Hello Andy,
I see the same but I do not know how to find the pin name or value. I don't know what to put on line 9 of the custom.hal file. Any ideas?

Well, I imagine that the pin name is there, but the numerical value is missing.
It would help to see what the line actually says.
what numerical value would you like? It's your HAL file.
