Jon Elson wrote: I include an all-electronic version of this in all my controller boards, and users can add external safety controls as they deem necessary. A latching relay is basically what you are looking for, it would then need a separate reset button. The problem with making it mechanical through the red button is that someone intentionally or accidentally jamming the button could prevent the E-stop action from happening. Same here ... The breakout board has both estop and reset, AND requires charge pump from the computer, AND uses 5V from the computer which can be used to provide an opening action estop in addition to the closing one. If computer power is lost then you have to 'reset' the enable signal before any output can be activated. In my own case I simply have power switches for the mains outputs, with over rated solid state relays to provide computer control. These should probably go through an additional contactor as well as the electronic interlocking ;) I am told so should the power to the stepper drivers, but if they are designed to switch OFF when the control signals are killed, then trying to rapidly kill power on the stepper motor PSU should not be necessary? I don't see the logic on stepper motor drivers that REQUIRE a signal to disable them? From a safety point of view you should need to ENABLE them to make them work? But the debate here seems to be is it better to lock the movement, or unlock it, and that depends on the mechanical arrangements that the motors are driving? Not that one should be relying on any actuator to hold something safely! Nothing should move under it's own weight when power is killed? But equally it may be necessary to USE the motors to move something out of the way after an emergency. Many of us work alone, so safety circuits ALSO have to be practical - not that anybody works without safety guards nowadays :) Having had a couple of close saves with the spindle starting up when it should have been locked out. I keep the separate power controls! You need to be able to move the machine - perhaps with a dial gauge in the spindle - so a single interlock is not enough. -- Lester Caine - G8HFL - Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk// Firebird - http://www.firebirdsql.org/index.php -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.

Neil Baylis wrote: Yeah, I've seen some of these devices. You wouldn't think e-stop could get so complicated. Get lawyers, and even WORSE, legislators involved in the process, and there's no limit to how bad it can get. If it has to absolutely stop the machine in a safe manner, even when a forklift spears the control cabinet, it CAN get complicated to design and test such a device. The problem with making it mechanical through the red button is that someone intentionally or accidentally jamming the button could prevent the E-stop action from happening. I wasn't thinking that the computer would use this as a way to stop the machine. Rather, the computer would stop the machine however it already does, but in addition it would press the e-stop, forcing the operator to twist/lift the button before resuming, even if he never pressed the button. Right, but I really think this is unnecessary. The way a number of commercial controls do it is with an E-stop button and an E-stop reset button. The Estop button is lighted to tell you what the state of the control is. Of course, if you want to rig a mechanically indicating E-stop button, you could do this and have a completely unique device.

Re: [Emc-users] Emergency Stop switch
Lots of over kill listed in this thread. First: Don't use a PLC for this! This is supposed to work even if the electronics is gliched. The system is really simple and ultra reliable if you keep silicon out of it. It only takes a hi-reliability multi pole relay and a high reliability momentary start up switch. One NO pole of the relay is wired in series with its own coil - this same line pass through NC contact of the E-stop switch and NC contacts of every other safety contact. A start up switch closes the relay - and then it keeps itself closed as long as non of the safety contacts, open or a power dip. The other poles energize the circuits you want to drop out on E-stop. The key feature of this setup is there is just three critical devices - the relay, the start up switch and the wire (this wire should make a loop, never crossing itself where it could get shorted and bypass the interlocks). If any of the interlocks fail(shorted on), the others still work. There is no limit to the number of interlock contacts you can add in series. Some interlocks to think about: Output of a good AC power detector Output of good DC power detectors Output of a Watch dog timer Multiple E-stop buttons - never be out of reach of one.

They are all designed with extensive fault-tolerant, fail-safe electronic and mechanical components. I include an all-electronic version of this in all my controller boards, and users can add external safety controls as they deem necessary. A latching relay is basically what you are looking for, it would then need a separate reset button. The problem with making it mechanical through the red button is that someone intentionally or accidentally jamming the button could prevent the E-stop action from happening.
