Retrofitting a 3-axis VMC with DC servos - guidance needed

Its okay if i make the config file with mesa ct?
And i need to make a simple config to test all or how is the correct procedure?
bw I test the ping for 60s and came with 0% of package loss.

Btw I am looking for the datasheet, connection diagrams, or pinout details for a Fanuc AC Spindle Drive Unit

Drive Model: A06B-6060-H003

Control PCB (Top Card): A16B-1100-0261/08B

I am specifically trying to trace the control signals and feedback interfaces (CN1, CN2). Since Fanuc doesn't publish individual datasheets for these part numbers, I am having trouble finding the exact schematics or the correct manual code that covers this specific board revision.

Note: I have attached an image showing how this drive is wired according to the machine's original electrical diagram. However, I want to verify it to be absolutely sure. It caught my attention that, in this original setup, there is no feedback loop going back to the old controller, which seems a bit unusual and is part of why I want to double-check the actual pinout.

Thanks in advance!

 

I managed to get the machine to power up and boot into LinuxCNC, and I’ve put together a basic configuration just to test it on the bench.

What would you do next? I was planning to load the driver for the 7i74 onto my 7i97T so I could configure communications with the other boards.

what are the differences between the 7i97t_7i74d.bin and the 7i97t_7i74d2.bin
What should i use?
flashing direcly from mesact is a good idea?

7i97t_7i74d.bin and 7i97t_7i74d2.bin differ
in that 7i97t_7i74d.bin has just one Sserial port
with channel 0 on the 7I97T and channels 1..7 on the  7I74

7i97t_7i74d2.bin has 2 Sserial ports with port0, channel 0
on the 7I97T and port1 channels 0..7 on the 7I74

The reason for the nearly identical firmware images is that 7i97t_7i74d
matches the older 7I97 firmware, and 7i97t_7i74d2 ( with 2 Sserial ports and
all  7I74 channels available ) wont fit in  a 7I97 with its smaller FPGA.
 

I flash the 7i97t with the 7i97t_7i74d2.bin.
now i have a bit of a trouble cause i looking to connect the 7i84u, but the trouble is i can´t understand correctly if i need to supply 5v to the 7i84u or is it supply by the 7i74 or its switched by VIN (and its need to be 8 to 32V) right now im working with all the parts in the desktop and dont have a 24V line here. i need to supply the voltage to VIN or im passing somenthing by.
Thanks

The 7I84U needs its own power supply.

You must supply VFIELDA and VFIELDB (Usually the same)
These set the output voltage and the input thresholds.
Normally VIN comes from VFIELDB (W1 LEFT=default)

 VFIELDA and VFIELDB are supplied via the ORANGE connector (TB1)
on the 7I84U.

There is a small 5V supply needed for the 7I84Us isolated serial interface
This comes from the RJ-45 connector, and in turn from either the 7I74 or
7I97TA.

 

Thanks, I understand it now. I have 1 more question.

Today I'm connecting the encoders and limit switches, but I have a question about the drive enables.

My machine has relays for the drive enables. Is it a good choice to keep those? 'Cause the 7i97T has optocoupled drive enables, but I don't know if it's a problem for the control or the board. I have to verify if the coil uses less than 50mA or buy new ones.

But is it good practice to have an extra layer of protection, or is it better to operate them directly?

You can drive small relays with the enable OPTOs
but make sure that the relay coils have flyback diodes.

I am working through retroftting a motionmaster. I kept all my relays. My goal was slightly different, I wanted to keep the wiring as stock as possible because there was a chance of the whole upgrade not working and I would want to sell it stock, but I think I'm far along enough that its worth more as a linuxcnc box now.
