Hi Alan,
This question has come up before. I previously suggested using four
separate switches, and I'm still of that opinion (I use four
switches).
Why not just use a little 4PST switch (also previously suggested)?
I normally run with 'A' switched off, and the other's enabled.

I have 4 Gecko 201 drives in a controller Im building. Does anyone
know if I
can connect all the Disable inputs together and switch them to
ground using
one set of contacts or must I switch the Disable line from each
drive to
ground using a separate set of contacts.
I'm a little concerned in case the drives interact with each other
if I just
join all the Disable lines together and let them float during
normal
operation.
The late model Gecko's can have the're err lines connected together.
So if one faults it will pull/fault the others. I had to build
Mariss's Fault Manager to do this because my drives were older style.
The older drives couldn't pull the others low. In the Gecko manual
there is a wiring diagram on how to incorperate a single switch to
E-stop and reset all the drives at one time.It only shows one drive
but just wire all the err pins together. It is page 4 for the G320's.
but works the same for all models. Term 5 can also be tied directly
to the printer port,it is TLL, to let your control software a fault or
reset has happened.
