Is it possible to use one servo motor as both spindle and C-axis using Ethercat?

Hi,everyone.I'm developing a machine,which need using one servo motor as both spindle and C-axis,and it's controlled by ethercat.I dont know how to make it using linuxcnc-ethercat.By reading the doc of cia402 component ,it seems to be unavailable to switch from csp mode to csv mode in realtime ,does anyone know how to make it done ? Thanks

Why the double post?
You have the same question on another topic here, or am i missing something?
Edit:
See below.

I suggested to ask in the Ethercat section as it did not seem to attract the usual Ethercat users.
If you could move the original thread
forum.linuxcnc.org/38-general-linuxcnc-q...indle-to-axis#304650
over to the EtherCAT section and delete this one then that would be much better.
Thanks

Ok, just read the other topic, all good.
Thank you.
