Hi Matt,
My impression in talking with the vendor is that the CK3M line is intended to replace the discontinued "Power Brick Controller" (without integrated drives) and eventually the Turbo UMAC (which is still alive but may be reaching the end of its life).
They told me that they don't currently plan to discontinue the Power Brick LV (or Power Brick AC).
Like Ronaldo, we're also planning to test the CK3M with external ethercat drives. The reason we're not using the Brick LV is that we need to drive steppers at a higher bus voltage, which the Bricks don't support.

Hi,
Out of interest, would this be the modern incarnation of the Delta Tau Power Brick LV? Except without integrated drives? I couldn’t find a complete integrated solution on the Omron website.
Cheers,
Matt

Hi,
I am writing to confirm that we are using the Omron CK3M in (at least) one project.
We are indeed using the pmac driver that Michael Dunning points to. Under the hood it is a power-pmac based motor controller. We have not yet used EtherCAT equipment connected to this motor
controller. My understanding is that any EtherCAT connected equipment will be transparent from the EPICS side.
>> Do you have a unit that we could use to test the controller?
We have a handful of these systems and I also heard reports of deliveries taking a long time.
Thanks,
Ronaldo Mercado

Hi Bob,
I'm not sure which one you're looking at, but the CK3M/CK3E use the PMAC API so should work with the DLS pmac driver.
I've been talking with Omron/DeltaTau and they've confirmed this.
https://github.com/dls-controls/pmac
We are in the same boat as you; we've ordered parts for a prototype and are waiting to receive them. As soon as the parts arrive I plan to test with the
DLS driver.

Is anyone using this generation of Omron motion controller?
Do you have a driver? Do you have a unit that we could use to test the controller? The order we placed will be several months to delver.
