huanyang vfd & linuxcnc 2.7

Thanks for this! There were a couple of errors on you directions for my version (loaduser rather than loadusr and some of the pins were incorrect), but this helped me tremendously. I can finally get my Spindle under control! Now i just have to figure out the servo's and encoders.

I have linuxcnc 2.7.4 and installed hy_vfd from here github.com/bebro/linuxcnc-huanyang-vfd/tree/linuxcnc.
How can install hy_vfd version included with linuxcnc and not from external repository?

vre,

Its already part of linuxcnc distribution. As a matter of fact I used your glade.panel for the VFD and your questions helped me install my system.

There are a few changes from the source code version vs the included version in linuxcnc, namely some pin names were change/removed (September 2015~)

Ill attach a copy of my configuration files so you can see them. When you created your hy_vfd from source did you then place it into you /bin directory?

Ill edit this post in a bit so I can post them from my machine.

EDIT: These should get you where you want to be. Im still in the process of finalizing my settings so there are some items commented out. But the VFD works well via MODBUS, well at least their version of it. Also with PD 165 I had to use 4 and even parity to connect. You can read it in my custom hal file.

Do take note that some pins were renamed and or removed in the distributed linuxcnc version of hy_vfd.

solved!
I found the pins changed and updated my hal config & gladevcp panel.
here are the pins changed & removed

thanks.

Hello all,
This is my first post. I feel a bit overwhelmed because this is not my field and i understand 15% of what i read.
I'm mechanical engineer and i have built my own 3 axis gantry from scratch. I thought CNCing it would be an easy task but i have lost half o my hair in the process.
Im sorry to sound that dumb, but there are tens of threads about problems connecting the huanyang vfd via rs485 and neither i understand nor none of them solves my problem.
I have a huanyang vfd 2.2kw, connected to my comp via a usb to rs485 dongle. I have tested it in windows using "spindle talker 2" working perfectly. In the "spindle talker 2" config it shows the parameters I set in the vfd panel "baud rate 9600" "data bits 8 parity none stop bits one" ModBus ID 1".
Back in Linux, I have installed Linuxcnc 2.7.14 in my harddrive. I have tried several tutorials/forum threads (marco reps, andypugh's explanations in tens of threads, James Waples website, etc) but i can't get it to work.
I open a terminal and type:
halrun
(if i type simply "loadusr hy_vfd" nothing happens
loadusr hy_vfd -d /dev/ttyUSB0 -p none -r 9600-s 1
show pins (and it shows every input and output)
setp hy_vfd.enable 1
After this last command it timeouts constantly.
(sorry I dont remember exactly what it says, my workshop is 30 mins away from my home and i don't have internet in my linux machine)
Im sorry to repeat again the same problem but i tryed everything i could before bothering anyone in the forum.
Thanks in advance

Thanks for replying!
I'm testing it right now.
I don't know what group i am part of (attach a pic "groups" showing what it sais"
Definitely my device is shown like ttyUSB0 (attach pic "tty devices")
I changed the vfd parameters to match your command line.
Pd164 changed to 2 (19200b/s)
Pd165 kept on 3 ( 8bit - none parity - 1stop)
My hy vfd is a "normal one" not gt.
I still get the same results when typing "setp vfd-spindle.enable 1" (attach pic "comm time out")


I think it's unable to read any parameter from the vfd. The only parameters that doesnt show "0" are "max-freq" and "rated-motor-rev" which were set manually.

I also attach a pic of the windows "spindle talker 2" config page before changing it to 19200 bauds.
Thanks so much for your help.

I have been testing again today. I don't know whether im doing something wrong or my usb dongle is not compatible with my machine desktop.
I have tried successfully established communications with the vfd using "spindle talker 2" on windows on my laptop, cables connected + with + & - with -.
On linuxCNC is what is making me lose my will to live.
I successfully load the hy_vfd driver, but once i try to enable the communications with the vfd i get different results depending on the way i connect the cables between the usb dongle and the vfd.
Connecting the cables + with + & - with - :
Connecting the cables + with - & - with + (opposite):
Weirdly, when i connect the cables in the opposite way, i receive some data back from the vfd?
I really don't know how to interpret this. I have triple checked that my settings in the vfd match with the command line i use to load the hy_vfd driver.
Does anyone know whats going on? Should i go with a rs232 to rs485 converter using the serial port instead?
Thanks in advance everyone!

andy thanks for ur help.
I wouldn't know how to use other driver on linux, so using another driver was was ruled out beforehand
My first option was to use a "NVUM" motion controller with mach 3 on windows. It worked fine untill i tried to connect the vfd through the 0-10v input. It stopped working. I bought a second one on amazon, and when I started comanding the spindle, it stopped working too.
So now I am using a DB25-1205 breakout board i got with the motors kit i bought long ago and give linuxcnc a try.
I guess there is a way to "step-up" the 5v pwm signal from the breakout board to 10v, but i would be losing some features like the current load and the rpm feedback, and I'm afraid of "burning" my breakout board, the same way as the "nvum" boards stopped working once i connected the 0-10v
I will try with the amazon converter you are using.
I am "using" the average USB pen with green terminals.

And yes, the windows Spindle Talker runs the motor flawlessly.
I will post whatever progress i make.
Big thanks!
