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

The 7I97T enable outputs should be able to drive that directly.

If you worry, you can always measure the current with a DVM
 

Thanks, i use new relays to keep that separation and use the old ones to the tool changer (not automatic, but to grip the tool holder i dont know how its his name in english) and another auxiliary, but i want to keep the 7i74 and 7i73 to the future in the end, I will use the 7i84u connected by the port in 7i97t.
Looking at the pins in it using the standar bin it will recognize the 7i84, now i have the bin of the 7i97t & 7i74 i will be a problem or its better to upload the standar?
And the configuration to connect the board its ussing this no?
 
Again, thanks for all the help.

If you use 7i97t_7i74d.bin firmware,  sserial channel 0 is on the 7I97T and
sserial channels 1..7 are on the 7I74.  (Physical channel 0 is skipped on the 7I74)

Perfect, ty so much.
I have a problem with the 7i84u.
In the datasheet mention W1 y W3
But apear W4.
What this do?

Hi everyone, I'm experiencing noisy/fluctuating readings on my axes. They are currently ungrounded as I just wanted to verify basic readings first. My main star ground is in the main electrical cabinet, but my Mesa 7I97T is mounted remotely in the old display/controller enclosure. I'm considering the grounding scheme shown in the attached diagram. Is this a good approach for logic signals, or will the extra connection points make it more prone to noise and ground loops?
