Hi Endian, I don't have anything for LCNC but I think I have some probing routines in a TwinCAT project and I can see if there is anything helpful in there.

I also posted an issue to your codeberg page for your converter for the EL3074.

I went back and carefully made the mods again, in case I missed something, but it still reports errors. Through a great deal of trial and error, I found that some of the configurations marked for removal must remain in the XML file for the program to run without error. Deleting any of the 0x60xx vars below cause many errors. Regardless, even with all the other mods in place, it's still stuck at "PrOp."

Hi everyone,
I’m working on a Yaskawa CACR-SR (BE1 series) servo drive. In general it works, but from time to time I randomly get A20 or A60 errors.

I have two identical drives, and I’ve already narrowed the issue down to the specific board shown in the photo. I was planning to replace all the electrolytic capacitors and also the film ones (I’ll probably do that anyway, given their age), but I also noticed component D20, which looks burned/blackened and has no readable marking.

I’m not an electronics engineer, but I’m quite good at soldering and I have a multimeter, so I can take measurements if needed. I’d really like to repair this drive because I have a milling machine that I only use as a hobby, and I simply can’t afford a new servo drive since I’m still young.

Could someone please help me identify exactly what D20 is (diode type and value), or point me to other likely components that could be causing these errors?

I wrote on this forum because I saw that in another topic an engineer had the same problem as me, but since it is an old topic I thought it was better to open a new one

Thanks a lot in advance for any help!
       

I am having trouble interpreting this thread, but it seems to have similar debug info to my problem:
forum.linuxcnc.org/ethercat/51505-new-hardware-trouble?start=0
Could my problem be EoE related?

I followed your suggestions and am running into the following errors:

This is the entirety of the linuxcnc command info
When I type "lcec_config" into the command line I get command not found.

Changing dcConf didn't seem to change anything...

Is there a guide on the linuxcnc forums to setting up Twincat with LinuxCNC? I can't find out, but I could try to figure it out without one.

how is your project coming along?

were you able to get this resolved?

happy to help and glad you got it sorted out!

Hi there, So i have done the same conversion on my 700c, I replaced all the scales except the B axis seeing that it's a Heidenheime scale. Any change you perhaps still have the HAL file. the Software side has stumped me and I am not sure how to start or setup the scales etc.
Delos W series scales used
5i25T
7i77 for the scale inputs and the 3trm2 and B axis
7i84 for the 24V relays and inputs
