Douglas,

Writing an asyn model 3 driver for the Ensemble is still on the to-do

list. If you need to do it, I would suggest using the profileMove

functionality of the model 3 Newport XPS driver

(XPS{Controller,Axis}.cpp) as an example.

We are doing multi-axis coordinated motion with Aertoech Ensemble

controllers at the APS using the SNL trajectory scan program for the

Ensemble, but the synchronization of the axes is less than ideal, since

a channel-access put is starting the motion for each axis.

My understanding is that multiple ensemble controllers can be

daisy-chained and configured to do true synchronized moves (using

Aeronet), but the downside of this approach is that the individual axes

can no longer be moved independently, which is undesirable for us.

Hello,

here at LNLS, we are using the asyn model 2 driver of the epics motor to

control a ensemble controller (Aerotech) that move two linear stages and

a goniometer stage, but we would like move two motors (linear stages)

simultaneously, and we saw that this is not possible using this asyn

model driver.

In this presentation about coordinated motion:

https://www.synchrotron-soleil.fr/fr/file/8469/download?token=x3GbKcgt

Mark mentions as a future work convert Aerotech Ensemble to asyn model

3, I would like if anyone has a update about this or are using

coordinated motion with ensemble controller?

And, if we need to convert to asyn model 3 for this controller, what is

the best way or examples to follow?

Many thanks,
