Yeah, I've seen some of these devices. You wouldn't think e-stop could
get so complicated.

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.

I'm sure that Pilz, Faulhaber, Schaffner and a bunch of other outfits 
have a device that will do what you want, in some manner.  I don't think 
I have ever seen exactly a red mushroom switch that would mechanically 
activate, but these companies and others have safety-rated relays (for 
about $400) and safety-duty PLCs (about a grand and WAY up) for these 
sorts of requirements.  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.

 Hi Neil,

 Setup a failsafe circuit with the connection passing through the
 E-stop
 contacts energizing a relay. If anything in the series circuit
 becomes
 open
 (E-stop button, relay contacts in E-stop circuit, overtravel limit
 switch
 contacts, etc.) the functions dependant upon that circuit being
 closed
 stop
 functioning.

Hi Neil,

I believe Eric is correct.  After 30 years in industry (the last 20
specifically with CNC) I have never seen what you are describing.  As Eric
mentioned, a relay that must be activated by a reset switch would do the
job.  Reset switches for this purpose I have seen and included in some of
the retrofits that I have done.

Have a good day,

Jim

My guess is that a switch with an actuator in it would be so expensive
that nobody has ever bothered to market one.  I think your best bet is
to have a self-powering relay that can only be turned on by a
momentary switch.

Setup a failsafe circuit with the connection passing through the E-stop

I'm looking to source an e-stop switch. I have some already with the
big red mushroom button that latches when you press it, and must be
turned to release. This is good. But what I want is a switch that can
also be operated by a signal from the computer. So if the computer
detects an e-stop condition, the mushroom button would pop down, just
as if I had pressed it by hand. I would drive it from a digital out,
obviously.

Does such a thing exist, and can anyone point me at a source?

Thanks,

Hi Neil,

That is easy doable by adding contacts on the E stop switch and creating the 
logic to achieve the effect you desire.

OK, thanks. I guess they don't exist.

I guess what I'll do is to add a circuit that requires the e-stop
button to be pressed before a fault condition can be cleared. Then I
have no choice but to twist the e-stop before resuming.

Hi Neil,

Setup a failsafe circuit with the connection passing through the E-stop 
contacts energizing a relay.  If anything in the series circuit becomes open 
(E-stop button, relay contacts in E-stop circuit, overtravel limit switch 
contacts, etc.) the functions dependant upon that circuit being closed stop 
functioning.

Someone may have a schematic example to share.  If not, email me and I will 
send you an example.

Have a good day,

Jim

[Emc-users] Emergency Stop switch

I'm looking to source an e-stop switch. I have some already with the
big red mushroom button that latches when you press it, and must be
turned to release. This is good. But what I want is a switch that can
also be operated by a signal from the computer. So if the computer
detects an e-stop condition, the mushroom button would pop down, just
as if I had pressed it by hand. I would drive it from a digital out,
obviously.

Does such a thing exist, and can anyone point me at a source?

Hello. Nothing changes if I try to execute (AXIS, stop) or (AXIS,
hide[show])

I am using EMC2.3.5.

Any suggestion?

Living with the NIST notion of "Sense -> Model -> Act" tends to limit
one from building the buffered motion system you're thinking of.  

EMC started as a servo based system with real position feedback not just
in the drives but at the heart of the computer system doing the control.
Servo position control is still central to all that it does.  Step and
direction signals were an addition with compromises.

I'll grant you that some step and direction systems lack the ability to
sense real hardware position so we get into lots of discussion about how
to detect lost steps.  

But at its core EMC senses all of the machine's state, including
feedrate override and rate of change and factors that state into the
next bit of motion rather than building an entire path ahead and then
apply changing state variables to that predetermined path.

[Emc-users] emc debian rules.

2010-04-12 Thread Jan de Kruyf
Jeff,
 I do not know if you are the right person if not, please disregard this.

I have a few problems with the debian rules file from the latest git
pull, trying to compile under debian lenny with kernel 2.6.30.5 and
rtai 3.8

here is the relevant line in the rules file:

cd src && ./configure --prefix=/usr --sysconfdir=/etc
--mandir=/usr/share/man
--with-realtime=/usr/realtime-$(kernel_version)
--enable-build-documentation=pdf
--with-tclConfig=/usr/lib/tcl8.4/tclConfig.sh
--with-tkConfig=/usr/lib/tk8.4/tkConfig.sh

the tclConfig I have added because the configure script picked up tcl
and tk 8.5 before 8.4
so that works now.

the next problem that is biting badly is the realtime spec:
--with-realtime=/usr/realtime-$(kernel_version)

rtai 3.8 does not make a realtime directory anymore with the
$(kernel_version) extension, it is just called "/usr/realtime"
I made a symlink, but the build process uses on the one hand the above
spec and on the other hand the spec from the rtai-config script. so
there is confusion with dh_movefiles.

lastly the rtai-config script was dumped in /usr/bin by rtai build
process, so perhaps the configure script must check there also.

I realize that this does not make things cleaner, especially if you
want to build with more than one kernel on the same machine.

I will fix all this, that is not the problem, but I like to hear also
some comment from the community, so the fix will be more of a
permanent nature. And perhaps some of it should rather be done in
communication with the rtai group.

Regards,

Jan de Kruyf.
