Does anyone see any issues with using Cat 7 cable (8 wires) for two encoders? I figured you can combine the power and ground to reduce the number of wires from 10 to 8. If shielded I think that would prevent interference if you are also running your motor cables next to it.
Thoughts?
Yeah I think this might work. Don’t forget to ground the shield on the ODrive side.
It will work best with differential encoders, actually. That way you can put each differential signal on a twisted pair and dramatically reduce common-mode noise.
Should I put both “A”, “B” and “Z” signs in one twisted pair in the CAT 7 or would that possibly present an issue?
As in Encoder 1 A and Encoder 2 A are in one twisted pair?
For best noise immunity, you should put GND in all the solid colors, and send signal in all the striped colors only (or vica versa).
Awesome thanks! It turns out I had other issues too so I am working on figuring everything out!
