Hi Alex,

did you ever manage to make any progress on this? From what google tells me, this is the only information on a bk1120 with linuxcnc-ethercat I could find. I have a similar setup for trying out and I'm stuck at the same point.

Generally I would argue that when devices coupled through a BK1120 to ethercat, than it should be possible to make that work somehow. At the very least on the level of ethercat on linux itself. From there on, the worst that could happen is some new programming within linuxcnc-ethercat. However, I would hope that a generic configuration would suffice.

I got a huge Problem with my ethercat bus

Recently died my old PC. I´ve set up a new one with Debian11 and the EtherCAT install thread pinned here in the forum. Then copied my machine backup, but every time i start my machine the OS freezes and the bus Stops. My dmesg after a hard reboot looks alike:

EDIT:
In the DMESG-Log it seems that Ethercat Telegrams get lost. Who is sending these Telegrams ? The EC-Master? or the Slaves?

This is my Config:

hello gentelmens,

have anybody some time to check what is wrong with my lcec config for one benchtop testing axis running under lcec please? driver waiting in preop mode and does not run to op mode. it is kollmorgen S300+ethercat motion card plugged in. I attached photo from original configuration program from that brand. there are some mapped PDOs. I tried used that PDOs but without any succes as running with my configuration of free mapped PDOs.

ps. configs are just for beginning with ethercat, for read stuff from drive and to try workflow.

thanks

regards foxington

hello,

I am struggling around setup a ethercat driver for working in CSP. I found some commands which are different then others in this topic. Is it my .xml code right please?

Have anybody idea of red rectangles in the picture please? Other stuff is clear to me.

Code:

hello,

yes I have done working core component for kollmorgen and pilz stuff with older incremental format for DC in 1 ms with my benchtop hardware setup - 3 axis. It is little bit more to setup but not complicated at all.

If you are interested check this stuff before.

have a great time

Slav
