Hi All,
I have been trying to get LinuxCNC working with EtherCAT and a Kollmorgen AKD Servo Drive.
I have been posting on this other thread:
forum.linuxcnc.org/27-driver-boards/3559...tall?start=60#159103
But I'm stuck on one last thing, and after sifting through this thread, you guys sound like the right audience. I didn't notice any other posts in here indicating the same problem though.
Basically I'm getting data to/from the drive, i started off using StepGen to control the AKD but now i'm using that project to cobble together an EtherCAT setup so i can update my mill and get rid of some signal issues i've got (low voltage parallel port).
Forgive the mess in the HAL/INI files, so don't assume anything is there on purpose and a bit is commented out. I had to use the SCALE HAL component to handle scaling (it's arbitrary right now).
The problem I have not been able to figure out is:
How do i get the EtherCAT/Can state machine to operate based on the enable/disable button in LinuxCNC?
My understanding is it's not a simple bit, the control word (which i have mapped in the pdo section) has to change a few values in sequence for the device to enable/disable, but i haven't found an example of anyone else doing that to enable/disable.
Anyone have an inkling what i'm missing?
