Problems with Lichuan Ethercat servo drive was created by trisa25
Hello,
I have ordered a Lichuan LC10E servo drive with motor for testing.
After following Rodw's guide I have successfully installed all needed software components. Ethercat slave also lists my drive speccifically in PREOP mode. I cannot get the drive to go into OP mode with opening lcnc nor with manually toggling the state with ethercat states -p0 OP command.
Any recommendations on what I can check first?
Below are my configuration files.
Kind regards,
Jan

Try this.
Looks like your
# joint signals for motion
are in the wrong place
move after
# ethercat to cia402 driver

Open a terminal and run "sudo dmesg -wH" to monitor for EtherCAT errors.
Start your machine and post what it complains about.

Here is the part that you probably need.
Attached file is the whole dmesg output.
Does this mean that this servo drives sii is not correctly configured?
I have also tested and can switch the drive between INIT and PREOP states.

I have now edited the ethercat conf first pdo idx to 1702 and second pdo idx to 1b02 and now i can change the servo state to safeop but still no other state.I can not upload servo manual because it is too large.

After a bit of searching I think that sii eeprom is not configured correctly on this drive.
I will ask the manufacturer for xml file in hopes of making it work.

Hi Jan
I have the same drive on order and hope I can do some testing soon. Very interested in the topic and your progress.

Good news the motor is running!!
Turns out if you try reading an ethercat adress that the drive doesn`t have, nothing works.
I have attached linuxcnc configuration files intended for testing only and LC10E xml (ESI) file if anyone wants to tinker.
Servo drive manual is available on link: drive.google.com/file/d/1qAFw_8SHKfR-JmR...Nqz/view?usp=sharing
Next on: try to implement higher frequency velocity mode.
