Hi everybody,

I am a little bit confused how to connect and set up my vfd with Linux CNC.

I have an USB <-> RS485 adaptor to do the connection between the vfd and the pc.
But now I am confused what I have to do, to setup the software correctly.

I tried this https://buildyourcnc.com/FAQ/13272https://buildyourcnc.com/FAQ/13272 but I doesn`t work with my vfd...

I read some information about mb2hal but don`t know exactly what to do now.
Can I use this with my actual version uf LinuxCNC or do I have to reinstall a newer version?
Which of these files exactly do I need?

Hope so much anyone can help me :)


Thanks a lot and best regards!!

Michi

How far have you got? Have you got as far as adding mb2hal to your HAL file and experimenting with it?

No I haven`t tried it, because I am no really shure what`s to do...


Do I have to do a new compilation for LinuxCNC with these mb2hal files (Somwhere I have read about )?
Or is the only thing I have to do copy and paste these in my project folder?

It might be a little simpler to use the modbus capability of Classicladder. But regardless configuring a modus control is rather complex.

Neither. You simply have to add an entry to one of your HAL files and create an INI file to configure the Modbus transactions.

linuxcnc.org/docs/2.7/html/drivers/mb2hal.html

This isn't quite as clear as one might hope, but you need a file rather like that example file, and also need to add a line in one of the HAL files
loadusr -W mb2hal config=config_file.ini
where config_file.ini is set up to suit the register maps of your VFD.

Hi!

I found help in a other forum.
It is in german, but if anybody has the same problems look there:
www.cnc-aus-holz.at/index.php?thread/124...62e8836da8a33fb2e0b9

This way is working!


Best regards

Michi :)
