Update
DMM Technologies added ZRI to the DYN4 Drive. So it is now possible to use the marker pulse on the DYN4 drives wired directly into Centroid Acorn's input.
IF you have to have this feature, you will have to contact DMM Technologies to exchange your drives. This feature can not be installed in the field.

I have a question for the community.
I just had my DYN4 servo drives replaced with the fix on the added ZRI feature and using the 1.8kW DMM motor as a spindle motor. My set up has 4 DMM motors with 4 DYN4 drives(X,Y,Z & Spindle).
I downloaded the latest schematics, however the DMM differs from the Acorn Schematics, see attachments.
1st Question:
On DMM schematics, it states to connect:
- Acorn H2 COM >> 5V PS >> DYN4 JP4 Pin11 & P22
On Acorn schematics, it states to connect:
- Acorn H9 COM >> 5V PS >> DYN4 JP4 Pin11 & P22
Does this matter or it does not matter which COM the DYN4 JP4 Pin11 & P22 connected to the acorn, H2 or H9?
2nd Question
On DMM schematics, it states to connect:
- Acorn H1 24VIN >> DYN4 JP4 Pin16
On DMM schematics, it states to connect:
- Acorn H4 24VIN >> DYN4 JP4 Pin16
Again, does this matter, as long as DYN4 JP4 Pin16 is connected to on of the 24VIN on acorn, H1 or H4?
I'm light on electrical/controls, so any help is greatly appreciated.
Thx, Nick

Do a search on this site for DMM Dyn4 draft schematic. You will find it under my Phoenix 4x4 router build thread. It is what I used and it works.
I don't think the Centroid Dyn4 schematic has been finalized. Only because the person that does them for Centroid has been out on leave.

Thanks for the quick reply Marty. I am minutes from spinning the motors for the first time.
