I have been on here for a while and have not seen these amps here on the forum that I can remember. Not to say they are not, but do not look familiar at all. Plus if they are not shown on the GitHub site, then I would doubt anyone has made the device files yet. Just as an example of how long it has taken to get more devices working, the Omron G5 device was just recently added and I have watched for a very long time before it was added.
I am sure "Chimeno" will chime in to help you and he is excellent with his advise, and may even be able to make the device files you need. There are a few others that are on here such as Grotius that may be able to help also.
Worse case you can always use the Generic driver for manual mapping to HAL pins. You do this in your XML file and that will get you up and running pretty quick to at least get going. Hope this helps a little.

I make an rip-install on ubutnu 18.04 ... seems all work goods, but after some test of connection I try to launch my first config and I can see problem with linkied lcec.so .... so I try with halcmd and see these ... (the problem is on 68, 108 and 113 page of these thread)
mine is rip-install ....sim axis work ok, ehercat slave output:
I see the error when launch command with halcmd .... not understand if someone has solve these without change ec-debianize version .... comeone can help me for these problem?

I control make file (modinc etc etc) and test with ldd some library as lcec.so libthethercat.so ..... I thinbk the problem was ec-debianize script .... seems not make for a rip-install .... so sometime shared library not match with respective folder on the SO ....
see mine ldd terminal output:
is my output correct or is there still some library missing?
Regards
bkt
see mine ldd terminal output:
demo@demo:~/linuxcnc-dev/rtlib$ ldd lcec.so
linux-vdso.so.1 (0x00007ffe1ead5000)
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007fa2a1023000)

Hi @btk,
are you sure you did:
during your linuxcnc-ethercat installation? See post : forum.linuxcnc.org/27-driver-boards/3559...-to-install?start=30 Might be different if you are using a RIP installation.
Nicolas
are you sure you did:
Copy some files across to the relevant location:
cp ~/linuxcnc-ethercat/src/lcec_conf ~/linuxcnc/configs/FolderWhereInIFileForConfig
to your linuxcnc sim folder (copy it where your ini files is)
cp ~/linuxcnc-ethercat/src/lcec.so ~/linuxcnc-dev/rtlib/
apparently only required for for linuxcnc_dev users
Make the Ethercat0 permission permanent for your user for linuxcnc
sudo adduser $USER ethercat
sudo adduser root ethercat
. Reboot to make it effective permanently.

on a std linuxcnc-dev rip-install all is intall inside everywhereWIthUserPermission/linuxcnc-dev .... so for sure I've copy lcec.so inside /rtlib, lcec_conf inside /config and I gave ethercat permission .... I read your tutorial but withut . . /scripts/rip-environment command not able to install correctly ethercat .... so after 3/4 test I use that command berofe install and all seems to work better in sim mode ... but when try to make my rt-config I' ve these error .... so for sure there are a problem with permissions .... I think ec-debianize try to write on /.... and not in /home/user/everywhere .... so dependency of lcec.so are unrechable from /home/user/everywhere folder .....
any how in your debian install what is the output of: ldd /rtlib/lcec.so ??

Try the solution here, it worked for me. You just need revert realtime.mk file then remake linuxcnc-ethercat.

@ thang -> Just try on ubunto 64bit ... not work for me ... to morrow i try on debian install. i remember I have a pc with debian linuxcnc strch ready ... so I try just now ... not work ... and reading some my old post I remember that these suggestion is not working for me 3/4 days ago.

@thang ... i undesrtand I revert a wrong file .... but I didn't understand how the realtime.mk file should be written ..
the file to revert is realtime.mk .... so
very thanks @thang
regards
bkt
the file to revert is realtime.mk .... so
- cd linuxcnc-ethercat/src
- gedit realtime.mk (clear all world in file and add these file .... after save and close ... copy the code I pasted below it comes from version 0.9.1 linuxcnc-ethercat)
- after these meke and make install for linuxcnc-ethercat
include ../config.mk
include Kbuild
include $(MODINC)
ifeq ($(BUILDSYS),kbuild)
# dirty workaround to get the RTAI directory
RTAIINCDIR = $(subst /rtai.h,,$(firstword $(wildcard $(foreach i,$(subst -I,,$(filter -I%,$(RTFLAGS))), $(i)/rtai.h))))
ifneq ($(RTAIINCDIR),)
RTAIDIR = $(realpath $(RTAIINCDIR)/..)
endif
all:
$(MAKE) EXTRA_CFLAGS="$(EXTRA_CFLAGS)" KBUILD_EXTRA_SYMBOLS="$(RTLIBDIR)/Module.symvers $(RTAIDIR)/modules/ethercat/Module.symvers" -C $(KERNELDIR) SUBDIRS=`pwd` CC=$(CC) V=0 modules
else
LDFLAGS += -Wl,-rpath,$(LIBDIR) -L$(LIBDIR) -llinuxcnchal -lethercat
all: modules
endif
very thanks @thang

I’m building a CNC mill and would like to have a fieldbus based control system. Ethercat with Linuxcnc seems to be one way to do it.
It looks like ASDA series servo drives from Delta are supported by this driver. Does the support include all models? I’m planning to use ASDA-B3. If they are not yet supported, how hard is it to add support for them?
Can the spindle speed be controlled with Ethercat? I’m guessing at least analog control with 0-10 volt signal is possible.
Are there any caveats in using this approach to build the control system? My goal is to make the control system simpler with Ethercat. If this would lead to overly complicated system then I’m looking somewhere else.

I'm also interested in Ethercat for Delta ASDA-B3 servos.
My understanding is I would only need:
LinuxCNC computer
Delta servos
(no other specialty cards unless I want more IO than the delta servos have)
I'm coming from using Mesa 7i76 for steppers.
