Problems with Lichuan Ethercat servo drive

This is fantastic. Thank you and Robbb and trisa and a whole lot of others. I just got my setup working.

video!

I'll get these motors and drivers any day now. I'm gradually figuring out the configuration. And I have a question, why specify these empty blocks? Will it work without them?

 

EDIT: Yes, they are needed.

please can those that have this working say the model. I've been looking at 3/4 80 series 23bit absolute with brake.

i would like to hear if there is a working config for the 32bit and brake before ordering.

I can confirm, everything works fine. Just in case, you can additionally compare this configuration with the documentation for your driver.

My model is LC10E, motor with 17 bit absolute multi turn encoder. 

Has anyone managed to get DO to work?
I added the following lines inside <pdo idx="1600">, but to no avail.

I also have this driver.  What are you using to power it?  I thought it might be my power supply.

Hello everyone

First, thank you all for the work put into getting these drives running with linuxcnc. This is amazing!

I have a setup with 3x 1 kW motors and 23bit absolute encoders which works perfect.

Did some of you also notice this high pitch whining noise originating from the drivers when they are online? Maybe coilwhine? Are there means to eliminate this? EMI filter needed?

Hey first of all thank you all for your awesome work!!
I have the same setup (I think) ( www.aliexpress.com/item/1005006913304675...n.112.45bb1802PVhuo5 )
And yes I can also hear the whining sound while the drives are active.
@Sandro would you be willing to share your whole config? I'm still very new to the whole config thing and the more files I have to compare to each other the faster I can learn.
