I hadn't explained myself well enough to Peter. The 0.1uF caps go to pins 8
and 5 to bypass the 5 volt logic supply. Either 0.1 or 0.01 are fine. Just
keeps the noise from the output switching down a bit.

Using the opto ioslators as voltage translators should work. Note the data
sheet has the words "not recommended for new design" on it. There is
likely a newer part. But maybe you have these on hand already?
These isolators will do 10 Mbits/second, likely fast enough. The
bottleneck is the RC
The caps go between pin 8 and 5 for each device. The 10uf just where the 5V
comes into the board..
This drawing may clarify it a bit. In North America the 220VAC is split phase
to provide 110VAC to a neutral. In the case of systems that use 22VAC and
110VAC they often provide the black, whit

Hi John,
Thanks for sharing the drawing. Yes, I would like to get things properly
drawn when I get the time.
In the mean time... would you mind having a quick look at the
revised schematic on the following link to check I have placed the
capacitors you suggested in the correct place when
Hi Peter,
I find it helps to draw a wiring diagram of where things are wired. That’s
different from a schematic which just shows how things are connected.
For example, I've attached the old schematic of my mill wiring (before I
removed the two HP-UHU drives and wired in the quadrature encoder f

Thanks Chris, yes, I will change the shielding ground to the controller end and
isolate the case.
Is it best practice to run the 5v and 12v ‘grounds’ back to the original 24v
power supply 0v?

Thank you Gene.
I’m in the UK and lightning strikes are unlikely where I am but I guess should
always be a consideration.
The grounding in my machine is not currently from one ‘star’ point so I will
correct that. Shielding is only terminated at one end.
Is the single point best on the machin
