VFD mb2hal

Thanks a lot! Have you maybe already succeeded to get a feedback from the VFD? Or realy found out whats needed to change in the hy_vfd file for the standart huanyang vfd for operating with the yl620? Honestly I dont understand how the commands are defined in the hy_vfd driver. As the functions are more or less the same in both models I thought its only changing of a few numbers, but as usual its more complicated...

Hi,

Huanyang uses modified MODBUS protocol with non-standard function codes. It's wrong idea to modify it back to standard MODBUS functionality Try mb2hal with config file for YL620 above, zajc3w said it works.

Also probably you will be interested in other way to communicate with YL620: forum.linuxcnc.org/24-hal-components/391...communicaiton#168359

yes the code of zajc3w works. It was quite nice seeing the first time the spindle switching on and off by computer commands.

Still I want to go further. Let's see. Thanks also for your advice with vfdmod I will have a look on this. The first impression looks a bit cleaner and easier to understand than md2hal.

Hi, I based my config for my YL620 on the one for this thread, but had some issues with it. Here is my working copy.

I also made some adjustment to my VFD Settings to help it work better at lower RPMs.
