err/res circuit

Have a look at this circuit for the err/res of 3 drives. Ignore the
3 contacts from the fault relays in the estop rung. I will move
those and a contact from the esr to a new rung with another
relay/contact going to the computer input. As drawn, a fault would
shut down all power to the drives. Other than that, does it look ok?

What happens is on powerup the drive reset timer contacts will close
for 6 seconds causing the drives to reset and the 3 axis fault relays
to come on. After that the relays stay on as long as the drives are
in a run condition. If one of the axis has a fault (or if estop is
pushed), that fault relay will drop out and cause a fault input to
the computer. Hitting the drive reset button will cause the drives
to reset again by cycling the power to the drive reset timer.

Thanks for any help.
