rs485 huanyang speed control

I am having issues with my Huanyang VFD and 24000RPM. It does not work. The usb device seems to be showing up.

I have a very custom .hal, but at a point, I decided that I would need to backup my original .hal and .ini create a new ones with stepconf if I wanted the controls to show up. I did that, and merged the new stuff into a copy of the old files.

Still, the custom controls showing in the example weren't showing. I figured out how to add the .xml in the [Display] section of Axis's settings, then I had the speed indicator on the right.

Though the motor will not turn on, and I don't have the + - speed selectors.
So it seems that perhaps I have to this all over again, making some spindle speed settings in stepconf, but will this fix my problem?

Because I don't know RS485 is actually doing, I have no idea what to put in for speed settings. I don't know what settings actually apply to RS485 spindle control. Is PWM sent over RS285 or digital data, or is the PWM a breakout terminal pin thing?

What I would like to have is spindle control on/off and RPM from perhaps 6000-24000.

It would really be helpful if I had a known-good .hal and .ini that I could fish through.



Any help would be appreciated : )
Thanks for reading this far,

Yes, I am using Axis.

I guess it thinks I have no spindle, so I guess I have to do another round with stepconf, and then the merging, and the sorting, with the pointy teeth : P

And I don't have any idea what stepconf settings applies to the Huanyang VFDs. In the video Marco Reps just glosses over the spindle page in stepconf--not important : P I like his videos, though.

My thinking is: most people will have a milling machine with a spindle.

Oh, the Axis internal controls are written in different language than the external ones....
One of the shames about Axis is: nothing is anti-aliased--no Cairo?

Thanks,

Well, as you know know most of my .hal is custom; you helped me with it : )

I just don't know what form of communication is happening over RS285.
Is RS285 sending PWM or data?

To read the hy_vfd man page, I would think that it sends and read data to/from the VFD, but the spindle control code I've seen seems to deal with terminal PWM, so how can it work?

It appears that stepconf has a PDM option, will that help it's speed settings work for RS485

In general the thing missing from the LinuxCNC documentation is examples of use and a sense of how things fit together, a lay of the land. A user who does not understand the documentation enough to soldier through it cannot improve it, and they will come here to the forums.

This would be a swell place to include some Huanyang VFD information.

RS-485 and the rest explained....it's data.

There's the man pages

linuxcnc.org/docs/2.7/html/man/man1/hy_vfd.1.html
linuxcnc.org/docs/2.7/html/man/man1/hy_gt_vfd.1.html

And probably more info available by searching the forum.

I've seen serial protocol before.

The issue I am having is: having never seen working code, having never found anything that explains how the speed setting connect with HY VFD, this I am shooting in the quiet dark.

Noticing that the VFD driver was written to support a Huanyang GT just sent a chill down my spine.

One young player had a bit of a problem, this thread discusses getting it going. Could be worth a read.

Further down the line, it's nice to see that there are setting for min and max speed, so that's encouraging.

Though....

I cannot risk ruining a $420 vfd and spindle combination. I want to learn how to fish, but unless I see example code, I don't think I should proceed.
