Jason,

This is not going to be the silver bullet you are looking for, but it may help. Attached are a Centroid schematic and tech bulletin, which applied to Taiwanese tool-changer machines ca. 1999-2000, using Fuji Frenic 5000 spindle drives.

Unfortunately whoever drew the schematic did not detail CN6 - CN9 at the Fuji drive. They did, however, label the PLC connections on the Koyo modules at the top of the page.

Input module 1 confirms what you already know: CN3-11 is zero speed, CN3-12 is at-speed, CN3-13/14 is a fault indication.
The analog module confirms that CN3-7 and CN3-8 are the analog speed command (frequency reference).

Output module 1 suggests that CN7-3 is the spindle-orient command (when closed to CN7-5 or CN7-6).
Input module 1 further suggests that CN7-2 is the orient completion signal from the Fuji drive to the PLC. Since that module has +24V to CA, it uses current-sourcing inputs, and expects the Fuji drive to close CN7-2 to 0VDC when orientation is complete.

It looks like CN6 is only for the star/delta contactor interface. It does not appear that there are connections from the CNC/PLC to tell the Fuji drive when to switch contactors, so the drive must manage those on its own.

It looks like CN8 is the incoming spindle encoder signal, which you don't need to change.
It looks like CN9 is the spindle encoder output to the CNC, and you have found enough information about that to connect it to the Oak.

I see in your list for CN4 the inputs from a control relay, related to a "rigid tap" command. Most likely that has the effect of reducing accel/decel time, or otherwise making the spindle drive more "servo-like". It wouldn't hurt to wire that to a spare Centroid PLC output, so that it is available if you want or need to experiment with it.

The attached tech bulletin related to the specific PLC programming and control features that Centroid provided 22 years ago. A lot has changed since then. However, there are some pointers in there for configuring the Fuji drive and setting the orient position. Those may apply to the drive you have.

Hey thanks for that, someone else sent me that same schematic, but I disregarded it as it has CN3-2 connected as well. did you get my PM? I'm drafting you a list of IO now.

Hi Marc, Ive had a good look over, and I think you are correct in your assumptions above. I’ll post an updated spindle connection spreadsheet today which I think will be right. How would I do +/-10v from the Oak though? I have searched beyond sanity and cannot find anything on the subject. I’m keen to take up your offer though, I’ve lost a whole week to this machine now.

HI everyone, I think I have this all figured out, sorta, here is the latest spreadsheet for the Frenic Pinouts.

I can't hardly wait to have this sorted and never look at it again.

With a Centroid factory PLC program, you use output forcing on the Alt-i screen to force OUT15 and OUT16 on. However, not all factory programs have the necessary calculations in the spindle speed section.

With my PLC programs, you add 4 to Parameter 178 (i.e. set bit 2), and leave OUT15 and OUT16 un-forced.

Thanks Marc, I'll just wait for your program I think. this is way over my head. I'm really just posting this stuff so the next person has a trail of breadcrumbs to follow. There's a lot of these frenic drives in Australia (and probably all over the world), No doubt someone else will be wondering this stuff again at some point so if I post everything I find out about it, the next person will be able to solve the problem quicker.

I can't pay back the favors of others, but I can pay them forward.
