I know it is not correct, but I don't find documentation on relationship between pdos output and definition.
Is there any good documentation I can use?

i have very less time at the moment.....
getting an ax5xxx running with the generic driver will get an very heavy task.
This is an SOE (Sercos) Drive, the drives stores no config data inside.
You have to complete config the drive with initcmds.( drive setup, motor data, pdo config etc.) every time you start lcnc.
the easiest way is to create an working drive config with Twincat, and then export the config data to get an initcmds.xml for the drive setup.
there are native drivers in lcnc-ethercat for the AX5xxx, for velocity control mode.
There are many threads with AX5XXX around here, where i have explained everything in detail....
there are also examples in linuxcnc-ethercat github.

Can you please explain, what this statements represent and where I can get values from?
Replied by boyzo on topic Beckhoff ethercat 64 with bit linuxcnc, How to install.
I did export config from TC2 and edit .xml . I use linuxcnc-ethercat / examples / initcmds /AX5206-AM8032-async.xml as example. Then I create ethercat.xml, but I do not understand several tags and values there.the easiest way is to create an working drive config with Twincat, and then export the config data to get an initcmds.xml for the drive setup.

oh, the example is very old...
We have done an native AX Driver in the meantime.
this is all needed for AX Drive.
the dcConf line tells the master the DC Parameters for the Slave (get it from AX manual or device description xml)
the other lines from the example are for setting up an AX with the generic driver

Very interesting. What motors would you pair with a AX2506?oh, the example is very old...

Should I include my generated without any changes or I need to modify something?

you have to use our AX5203.xml . Initcmds looks ok.
Seems that there is one </initcmds> to much at the end of the file.

More I dive deep into, more questions I have.
How do I define hal I/O bits and other values I want to use, as example from AX5203.xml I want to use position feedback value 1

How do I use some other functions like DriveEnable? How do I find and define correct bit in my xml file?
Is internal communication between lcnc and drive done through ethercat telegram?
As I see, you put enormous amount of work in lclc ethercat project, but what I can not find is some documentation that I can use and find most of this answers by myself, not bother you every day.
Many thanks
