CANBUS networks for closed-loop motor control

[Moshe]

Hi all,
I am planning to use CANBUS networks for
closed-loop motor control at 2-5khz
which protocol is recommanded?
Thanks, Moshe

If you're going to be passing feedback and commands on the bus at those
speeds do a loading analysis of your bus -- you won't get many loops on
there even at 1MBPS.

I'd pick a protocol that will coexist with other messages flying around,
and hard code the motor feedback and drive messages in standard-length
identifiers. I _think_ CanKing can do this, but I don't _know_.
