With Linuxcnc running and a  S1000M3 MDI command executed,
 what does:

halcmd show all | grep pwm

report?

(halcmd typed in a terminal window)

Wow.! Thank you for the deep explanation.! Let me try that. Because I am no fan of step/dir method which is unreliable and prone to many isues like EMI. Since Ethercat is free and Ethercat Based servos have become relatively inexpensive. I am going to give a shot. 

If the comp table is backwards then the interpolator function will only ever read the first value, so you will get a fixed offset, and no apparent compensation.

Your HAL looks correct.
When you say "in the oszy" do you mean in the HAL oscilloscope , or on a physical one?

In the HAL oscilloscope try scoping both the index-enable signal and the hm2_7i80.0.encoder.00.input-index pin.

If index-enable is high then it should go low when the (short) input-index pulse is seen. 
The index-enable pin should go high as soon as the home switch trips. 
 

  Hello,
between pins 22 and 23 I find 10V
between pins 22 and 24 also 10V
I don't see any change if I lower the speed
if I stop the spindle
between 22 and 23 0V
22 and 24 10V

Thank you

I think it was an attempt to link to this thread.

And now that we know that it is CigWeld CutSkill, not Gig SkillCut we might have more idea what is being discussed.

As setup, if you have 10V on Spindle+ (7I96S TB3.24) and you run s1000M3
in MDI, you should get +5V measured from Spindle-Out  (7I96 STB3.23)
to Spindle- (7I96S TB3.22)

(you do have to home the machine before MDI will work)

I would verify this before worrying about the VFD setup

 

No, there is no built-in version of this, but I have seen demonstrations of it on Youtube.

However, it should be relatively easy to configure with LinuxCNC using external offsets.

An example of using this is in this video:

The trick is to calculate the required offset based on a non-integer factor of the spindle rotational position. 
How many lobes per rev you would need is something that might need some consideration, and might depend on the working diameter. 

The closest HAL component to what you need is probably "relief,comp" here:
github.com/andypugh/HalComps/tree/main

Try a small value for FF1 so it starts to rotate. Then add P so it stops.

Ciao e grazie per il tuo aiuto.
In teoria, ho impostato i parametri del VFD come segue:
P00.01 1
P00.08 3
Ho trovato questi valori online, ma a quanto pare non sono sufficienti.
Quali altri controlli potrei fare? La velocità sembra essere impostata su un valore e non riconoscere i comandi  in MDI.
Durante il test, sembra essere impostato sulla velocità massima.
In effetti, trovo 9,9 volt tra GND e pin 10V.
Grazie
Milko

I don't see anything obvious wrong in the hal/ini files.

What is the actual issue with the spindle speed?

You might need to measure the 7I96S Spindle+ and Spindle output vs Spindle-
at various spindle speeds to track down the issue.

It might also be a VFD setup issue. (if the voltages are correct but the VFD does not respond)

The module psutil was removed 5 days ago.

Can you post the complete error?

How did you update?

Ciao, trovi i due file allegati. Grazie per l'assistenza. Milko
 
 

When a sentence starts with "Again," it functions as a conjunctive adverb, requiring a comma immediately after it to separate it from the rest of the sentence. This usage is grammatically correct and can effectively add emphasis to repetition, the return to a previous point, or a second example.

Google -> "In CNC, MEM mode, or Memory mode (sometimes called Auto mode), is the operating mode where the controller executes a complete G-code program stored in its internal MEMORY, allowing the machine to perform automated machining cycles for production."

After being piled on by a pack of folks, that can only be described as: Deliberately obtuse.
I think I'm just going to the smart thing and just never mind.

You all have a nice day. Take care now. Bye-bye then.
