rs485 huanyang speed control

forum.linuxcnc.org/24-hal-components/34617-mesa-modbus#111139

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.

This any use ?

Thank you.

I saw where someone uploaded their whole setup, but I didn't see anything regarding spindle speed ranges, as outlined in the Huanyang module man page.

I feel bad about LinuxCNC because the documentation is not getting updated by those people who know it, and I can imagine those on the forum likely get burned out after a while from helping people. I can see many of the new users being frustrated by this as well.

For LinuxCNC to flourish to its potential it will need to outgrow this problem. The only other open source project I have seen this problem with is OpenFoam CFD.

I have gotten some good advice here on the forum from knowledgeable people who knew not only what to do but what they are doing, but I feel bad to have to ask for it.

Both OpenFoam and LinuxCNC have in common that they are not only very powerful, but very adaptable. So, this introduces a new problem: a new user will have too many possible things to learn and consider at once. This is why examples are so important, because they show a restriction, a cordoning off, or a direction taken with those possibilities.

This thread concerns, for better or worse, the single most prevalent VFD on the market, likely but not exclusively hooked to a Huanyang spindle motor, but no commented .hal.

I think, and I agree, that most here will guide someone towards the right answer, rather than give a complete solution.

Reasons for this being a good way of dealing with questions.
1; The person asking the question will gain knowledge.
2: Sometimes the question being asked is not the "right" question.
3: Important information regarding the questioners' setup is either missing or not correct. (This can be a blameless situation)
4: The hows & whys will be touched more often when someone is guided towards the answer.
5: People will try to come up with an answer and questions will be ask as to why this particular way does not work......More information is available.
6: Sometimes a posted config just doesn't work......I'm helping another Sydney sider getting a DE0 SOC nano working with Machinekit and a supplied example seems a bit iffy..but when sorted we'll both be the wiser.

If you haven't seen Andy's post on testing a vfd, maybe this could help, I can't see how you could make too many things go bang if your vfd is setup correctly.
