Problems with Lichuan Ethercat servo drive

ooh, nice. you think you can help me config my ethercat setup. i have different drives, but im stuck at the "how do i even make ethercat work" part. 

i looked through your files a bit, but of course they dont start cause i got no mesa card in mine.

I'm new to this and was asking Chat GPT what the problems were with Lichuan drives. It says EtherCat Master stacks on Linux CNC expect drives to follow CiQ 402 correctly, but Lichuan drives lack full state machine compliance, and incorrectly transition from Ready to Switch ON to Operation Enabled, etc. Windows stacks are more tolerant of violations. So by plugging the drive in after they have done an illegal transition, Linux CNC stacks remain happy.

@John,

Maybe that's the case, but this is solvable.

I am writing some new code. We are free to change the state machine transitions for Lichuan.
Here you can see how to set states. In fact it's just a matter off setting a combination off bits in a sequence.

Currently i am waiting for a new servo drive, so my code is halted. I dont have a Lichuan here, so i can not write code for it
to solve any problems.
 

I guess ChatGPT looked at this thread to come to that answer.
I read more than half of this thread yesterday. Some 8 pages or so in there are many working configurations, and people with success.

Yeah this thread is really the only reference. The first post maybe needs a consolidation of "this is what we do".

I'm curious about tuning these things now that we know they "work". Would like to know how arduous or easy that turns out to be.

Hi, everyone.

Probably, I have a same problem.
I have LC10E V1.11.xml. ( from sellers )

How do you write eeprom V1.11(?) to attached V1.04 to drivers ?

And I'd like to know why do we have to use older version.

See previous post #315502 from November 2024 which has a link where stirra kindly still hosts the files you're looking for.
Note that he cautions you to check with Lichuan support if there are any updated firmware/uploading tools available in case those files should be outdated. Hope this helps!

Thank you. I tried both V1.04 and V1.11.

But I couldn't make servo drive move in LinuxCNC main screen.
I didn't see any error on screen,  but servo drivers didn't become "Servo On" state when I pushed "PowerOn"

Where do I need to check ? ( I used to use another tiny LinuxCNC system and machine , but it was stepper.., I used step conf. )
Do I have to set some servo parameter from switches on servo driver ?
( No load is connected to servo motors for now. )

Servo Driver Panel shows "20ry" (2 is blinking.)


I tried both V1.11 and V1.04 and this configuration,
forum.linuxcnc.org/ethercat/52341-proble...rive?start=60#304887

I have 3 sets of Lichuan Servo (Driver+Motor), I want to use them as XYZ CNC.

(SOLVED)

I compared V1.04 and V1.11 EEPROM Files.
And tried to understand configuration files.
I found my cnc configurations were mixed for V1.04 and V1.11.

Lichuan sales person said, we should use V1.11 with LinuxCNC for some reason.

Now servo lock is working by pressing PowerOn button.

Hi all.
LC10E - magnetic encoder 23bit.
Servo in standby mode - motor not powered, i see encoder position moving near +-10 counts - only at me have that strange ?
