Ethercat HAL driver

Beautifull!!!

Can you put some data about universal joints, rods, etc (manufacturer, models, etc)

Very Nice! Can you show some details of the upper arms and servo drives as well?

Hi Sascha,
Thanks for the excellent effort and library. I integrated 2 panasonic A5B ethercat drives with linuxcnc.
Thanks to your library, the integration was effortless.

My config: Debian Wheezy with 3.4-9-rtai kernel on the linuxcnc 2.6 live CD. Latest master from linuxcnc git

I have attached the xml file that was parsed with lcec_conf

There is one issue with the linuxcnc-ethercat repo at github:
github.com/sittner/linuxcnc-ethercat/blo...ster/configure.mk#L1

it is expecting "comp" to process the lcec at github.com/sittner/linuxcnc-ethercat/blo...ster/configure.mk#L1
It should be changed to halcompile as comp has been renamed to halcompile since mid 2014.
We should check for comp or halcompile and include the relevant paths.

Hi,

I'm looking at developing a Yaskawa based linear motor machine using SGLFM coils and 2 meters of SGLFM ways.

The drive would probably be a Yaskawa ServoPack Sigma-7 with EtherCAT - fully closed loop with linear or absolute encoder.
www.yaskawa.eu.com/en/drives-motion/ac-s...a-7/description.html

I'm sure I spotted a chap on here tthat had Yaskawa/EtherCAT working. I'll do another search. Could this be a fairly straighforward coding job to support this setup? Alternatively I could look at Mesa / pulse version of the ServoPack. The fully closed encoder feedback intrigues me, especially the vibration suppression.

What are the pros/cons by closing the loop at the ServoPack rather than the linearscale being connected directly into LinuxCNC via MESA?

Thinking something along these lines. The encoder is directly attached to the ServoPack.

Would the EtherCAT module/driver support feedback through to LinuxCNC from the ServoPack?

Hi Narogon

This looks really lovely

I have 2 Omron drives the same you are using except its 400watts instead.
My plan is to have these to on my lathe and would really like to test this ethercat communication.
I use ethercat alot at my work but have never tried it in Linux cnc.

- Can you maybe tell me more about your application and maybe put up some example file?
- What is your configuration on the Beckhoff I/O node?
- My idea were to put a hand / jog wheel like and MPG on the Beckhoff node and some other I/O for the toolchanger.
- Did you use CX-Drive from omron to tune and set up the drives?

I am thankful for all the information you can tell.

Thanks

Best regards
