Leadshine EL7-EC400N ethercat error 818

Hello everyone,
I'm new to the forum, I just bought two Leadshine EL7-EC400N ethercat driver servo with Leadshine ELM1 AC servo motor 400W to start my new cnc projects.
I installed linuxcnc-ethercat following @Rodw's Ethercat installation from repositories documentation and i created a .ini config lithe axis with two axis X Z, and a hal file and ethercath-conf.xml, but every time I start linuxcnc I get an error 818,
My question is whether the Leadshine EL7-EC400N is compatible with linuxcnc or not?
and also I'm wondering if there's anyone who can help me or give me a minimum configuration (.ini, .hal, .xml) file to make the motor start and get past error 818?
I used rodw's configuration
github.com/rodw-au/linuxcnc_leadshine_EL8/tree/main

It says it is an CIA402 drive, so should be compatible.
Maybe someone has a working config to share.
Here is otherwise a starting point github.com/dbraun1981/hal-cia402/tree/main/example
hal and ethercat-conf.xml should be enough to get one axis going. Expand from there.
