Beckhoff Compatibility

Hello, 

I have been looking around planning my CNC conversion and it seems Beckhoff is the main choice for Ethercat.

I am planning to use the following

EK1100 Coupler
EL1018 Input
EL2008 Output
EL3048 / 68 - 0-10v Analog input
or 
EL3058 - 0.4-20Mha Analog input

Now from what I understand I can use the EL3048 / 68 or EL3058 to read some potentiometers which I plan to use to override Spindle Speed and Feed Speed.

Now will I have any issues with using these? I have not come across someone else using them on Linux CNC. Is there a compatibility list or certain drivers required for these Beckhoff components?

Any tips or feedback is Appreciated
 

Hi,

EL3048 / 68 - 0-10v Analog input
or 
EL3058 - 0.4-20Mha Analog input

These are here : github.com/linuxcnc-ethercat/linuxcnc-et...evices/lcec_el3xxx.c

So everything should work.

Greetings.

Exactly what I was looking for.

Thank you

What's the odds of getting a Module not listed working? The one in question I am looking for is not listed in the Github

EL2088 - 8 Negative Outputs | Supported
EL2889 - 16 Negative Outputs | Not Supported
EL2809 - 16 Positive Outputs | Supported

Will it be possible to get this working or does it have no drivers?

Hi,

As long as a unsupported driver is close to a excisting driver nr, we can write some code for it so it works.
I am not very familiar with servo's, but beckhoff EL- stuff is not that hard.

Just order it, no worry's. We are here to assist.

I am in the middle of building an EtherCAT system using a Beckhoff EK1100 and would like to use the el6021 module to drive my spindle VFD with RS485.
I've searched the forum and seen it mentioned briefly a couple times but I can't find where anyone has got a driver working for it?
How hard would that be to accomplish?

You can drive the VFD directly with RS485 via a USB to RS485 adapter without bothering with Ethercat. Worked perfectly for me.
I think if you wanted to use Ethercat to drive a VFD, you would use a Ethercat compatible VFD.
There is a Omron MX2 driver included. but I have never used it.
 

Ok, that is what I'm currently using and it works well, I thought maybe it would make more sense to run the VFD through Beckhoff thus all connections to the PC would be EtherCAT. I'll probably continue with USB.
Thanks!
