Hi all

I have found a Kollmorgen servo drive with ethercat that seems to match my requirements, the part number is AKD-P00606-NBEC-0051. But I am not able to find any info on the option code -0051, anyone knows?

@andrax,

Thank you for posting the A6 encoder and homing information - very helpful.

If you don't mind, I have a few questions directly related to your post:

• Step 6 - I assume you mean trigger the drive's internal homing routine, yes?
  • If so, what homing method (of the 33 available) did you select?
    • Reviewing your HAL file, it appears you have a home switch connected to one of the drive's built-in input pins - is that what you used to home the servo?
    • How did you trigger the drive's homing routine?
  • If not, can you clarify "perform a reference run"
• Step 7 - do you mean adjust HAL and INI files as you've described in your post, or some other adjustment?
  • Maybe once the servo is homed, you calculate the joint/axis max & min limits and put that in the INI file?
• XML file - can you post your xml file please?
  • That would help me, and perhaps others, understand the various lcec pins in your HAL file

Again, thanks very much for assisting the LCNC community.

Hi Rodw,

Cool,
When you go shopping, look for Intel NIC's if you can.
The translation I was referring to was my tuner.
We have only ever spoken English here so I don't know anything about how translation works in Linux.

When you install my ISO it does ask you to select a language for the Debian Operating System.
It also installs the LinuxCNC documents in several languages. I thought Linuxcnc would follow your language.

I also have a motor design spreadsheet on my website too but it won't do the C axis.


 

Oh, that sounds great! 
I still have a PC sitting in the basement; I'll use that for this. First, I'll get two network cards and install them. 
1 x Internet, 1 x EtherCAT, 1 x Mesa Card.

Then I'll install your ISO. 

> I can probably add German as a language now the framework is there.
What do you mean by that? Do you mean German for Linux, for the installation, or for LinuxCNC?
Having a German language option in Linux would be great for me; I'll let the translator handle the English. 


> I guess it could be made to do that but it never made sense to use both at the same time to me.
I wouldn't prefer that either. My problem is: My machine was built with stepper motors, and I don't know the actual torque required. 
That's why I've now purchased this A6 750 W AC servo.
I want to replace just one stepper motor at a time with this servo and check what torque is actually required. 
Once I know all the torque values for my machine’s X, Y, Z, and C axes, I’ll buy the appropriate servo motors and convert everything to EtherCAT servo AC. 
 

Yes its a complete system.
The optimisation/tuning for a NIC for a Mesa card is the essentially the same as ethercat, just different installation steps.

It installs Ethercat, optimised the NIC for it and configures it to use the optimised NIC.
Yes it will configure a NIC for Mesa with the 10.10.10.1 Ethernet IP address on the assumption that the Mesa card is on 10.10.10.10
I'm not sure if Mesa and Ethercat could be used together. It was never intended to do that. I guess it could be made to do that but it never made sense to use both at the same time to me.

These are the new commands I've added recently from the --help page
I can probably add German as a language now the framework is there.

Note some tuning functions are not preserved on a reboot so the --autostart function installs a service to run the tuner again in a passive mode to set them on startup.

+1
Also wish to have option to remove G54 on M2/M30
Thanks

Hi Andrax, 

 das sind 30 Seiten, das dauert, bis ich sie übersetzt und gelesen habe. 
Das auf GitHub werde ich mir gleich mal anschauen und schauen, ob ich verstehe, was gemeint ist. 

Hi Rodw, 
Is your ISO a complete system? (Linux + LinuxCNC)? 
Can I use your ISO to integrate EtherCAT and the Mesa card? 


Regards, Mücke  

How many of those 30 machines run Bookworm or Trixie? I used to think like you.  In my view its mandatory today and I get much better latency results on the same hardware I used with stock kernels back when  we used to have to compile the PREEMPT_RT kernel to run Mesa cards. One day you will strike a PC which will cause you to rethink your views the hard way just like I have.

but my tool is only for viewing, not really for editing

Again, thank you, but again, i never ever used isolcpus in my life, yet i have over 30 machines running LinuxCNC and Mesa hardware happily, every day, on mostly industrial machines, for over 10 years.
Still, i understand that sometimes isolcpus and some other tuning can help.
P.S. that 30 above does not include over 15 PC's and laptops i own, all with LinuxCNC and used on machines with Mesa boards, and therein lies my dilemma, i have plenty of laptops that run LinuxCNC out of the box, but i can not advise on getting the same laptops as i had two of the same make and model where one was OK and the other was utterly useless. And i use USB-to-LAN adapters and switches, but i never ever advise others to do the same thing, as i am fully aware of the consequences, if something fails.

I did not say to switch slots, although that might help on old PC's or if the memory pins were touched during installation, i said to test each module, one at a time, and that is still valid advice, had new 16GB module fail inside a week lately, out of 6 modules one failed, and the PC will boot with it and work till starting new apps does not work anymore and the PC reboots on it's own.
Sent it back for replacement, got it back with the note "it works fine", now i have to call tomorrow (well today as it is 5:15AM here) and explain to them that booting windows does not work as a memory test.
I did test it, on 4 motherboards, on 3 it works and memory test fails miserably, on one board it will not boot at all, even after BIOS reset and XMP/EXPO disabled.
The other things that might cause such issues, power supply (hard to check without replacing, needs a scope), and in your case might also be the motherboard as A520 are the low tier for AMD, so signal integrity for the memory controller might be compromised, although AMD is pretty damn good at fixing errors.
But first, disable XMP/EXPO in BIOS and test.

  The original computer I was trying to use was built off an ASUS A520m. I did do a RAM check. They both reported working fine. I have 2 8gb sticks, running together for a total of 16gb, details shown in the screenshot. Why would switching RAM slots matter? 

Ooops, I saw the pings but missed the disconnect window. So to my mind, the only things that could cause this is faulty hardware, crappy network cable or a flakey power supply on the Mesa card. The Mesa power can be eliminated at this point. Time to follow PCW's advice to isolate that piece of hardware is causing it.

But the ping times are also too slow.

None of my suggestions are out of scope  of a  mesa card and earlier screen dumps showed no isolcpus was set so a lot of work to do there
