huanyang vfd & linuxcnc 2.7

my config has hy-freq-command commented out in custom_postgui.hal also.

So no hope here..

can you double check pd002 = 2?

I am rapidly losing interest in trying to help here.

If there is no connection in HAL between the commanded speed from the system to your VFD then of course it won't work.

You need to configure the HAL so that motion.spindle-speed-out is connected to the VFD frequency command, probably through a scaling function. (though you can probably scale in the VFD, so that might not be needed)

You can't expect to be able to configure a non-standard LinuxCNC installation without understanding HAL. Read the documentation.

if your pd002 is already set to 2, zip up your whole config directory and post it, I will try to figure it out.

stepconf sets puts "net spindle-cmd <= motion.spindle-speed-out" in the main INI
then custom.hal should have "net spindle-cmd => spindle-vfd.speed-command"

that should be connected to the VFD through the hy_vfd component.

Here is my config


@andypungh sorry for my bad english
'here' i mean commented line in pyvcp gui has value 500 constantly

It looks like 2.7 changed some names for spindle pins.
you have 2 options
option 1.

in 6040-parallel.hal, add this to line 24
option 2
in custom.hal, change the very last line to read
If anyone wants to update the files in the first link, (sorry I'm not familiar with that), option 1 should keep compatibility with 2.5+, option 2 should only work with 2.7+
I think.


VRE let me know what happens, should be an easy fix.

Now works with the change to custom.hal. I can set the rpm from linuxcnc.
thank you.

How can i move huanyang gui from right to an axis tab?

Hello there,

In fear of flooing the forum in new threads about more or less the same ting, I hope to highjack this thread a bit.

With 2.7 now including a huanyang driver i want to give it a shot at my first tinkering outside Stepconf.

While trying to wrap my head around it all I read basic hal and the manual pages (hy_vfd part)

I still dont get how you would know what to include. I mean where do you begin to figure you what to use, and to what pin?
I have been scratching my head reading and watching the examples in the thread, but I cannot get it start the app, getting one error efter another and not really seing the redthread in it all.


well..long story short:

Does anyone have a working setup using the huanyang driver i could have a look at?

As you can imagine im very new to both Linux and Linuxcnc, So any advide anyone give me needs to be teaspoon seize
