Re: err/res circuit(updated picture)

Here is how I ended up doing the err/res on the geckos.

When I power up the machine a 6 second timer resets the drives. The
drive is then able to drive the transistor on it's own via the
err/res pin which is +5 when all is well, which holds the xfr (x
fault relay) and the external LED on. I didnt show yfr and zfr but
they are done the same. If the drive faults the err/res pin goes to
ground which turns off the transistor which turns off the fault
relay, and the LED. Once the fault relay turns off, it breaks the
rung bellow all that stuff to the computer input. Not shown in that
rung is contacts from the estop and from the overtravel relay (which
is wired to the overtravel switches). If a drive faults they can all
be reset by hitting the drive reset button, which starts the timer
again allowing the six second reset one shot.

It's working great. Any comments? I wanted to use 5 volt relays but
I couldn't find any so I went with 12 volt relays.
