Gecko Fault Circuit

[bgolash]

Hi All
A forum member in another group mentioned a simple circuit
to halt movement if one Gecko lost position. I`m wondering
if anyone has used this approach. The Gecko site has a similar
circuit but as the person describes it, his is less complicated.
I`m wondering if anyone has a diagram of this circuit. I tried
posting at the Gecko site on yahoo but you never get much help
there.


"I'm guessing that you have the err/reset tied to encoder+ so that the
Gecko auto resets on faults. I don't like that configuration because
it is possible for one axis to stall/reset and continue with a loss
of position and a ruined part. I would suggest tying all the G320
grounds together and all of the err/resets together. If one axis
faults they will all fault and stop all movement. Use a momentary
switch to connect + to err/reset to reset all Gecko's at the same
time."

Hi Barry,

My 320 Geckos are running fine with this ERR wiring setup. The circuit is simple, Tie all the ERR connections together. If an error happens on one servo, all the servos stop. I use a three position momentary switch like in this diagram.

Hi

With the help of another DIYer, we have a circuit drawn. Greatly appreciate
someone double checking the wiring. I`d hate to kill one of my geckos.

How do you like you Geckos? Well done or extra crispy?
The AC ground could smoke them.

Take a second look at the diagram I posted earlier.

The center tap is the ERR line. top tap is +5vdc Bottom tap is DC ground.
