But by the time I got them switched, and the last spindle problem solved, 
it was way too late to make the P.O. And I still have a new swarf wiper 
to make today.  So now it won't leave here till Monday.

Thanks Peter.

Thats not right either Peter, it was my dumbassed mistake, not yours.

I called myself giving it a good inspection as I was makeing that socket, 
but obviously not good enough. I'm still fighting with my plastic eyes, 
plenty sharp, but depth perception at short ranges doesn't seem to be 
quite as good. I'm using a lot of those Hilitchi crimp-on pins, and I 
don't always hit the hole in the rear colored socket that well. A year 
ago, even with my cataracts, I was doing a lot better. Frustrating, & 
forcing me to admit I'm not the man I once was, not even once.

But I'll see if I can get it back out of there tomorrow, and I still have 
the box & most of the packing from the 2nd one. I'll just put the 2nd 
one in this box, and wait for the fixed one for the 6040 gantry.

Thanks Peter.

Thanks Peter.

the y motor, giving me back a sorely needed additional inch or

shield was too long and was hitting the motor mount.  If I clear
that, I gain nearly 1.5" of y motion. When I put that bellows

Now, a question for Jon:

Normally that 12 volts to the logic on pin 6 will be present
anytime the interfaces line cord is plugged in, and which I intend
eventually to plug into the power strip that feeds the rest of the
motor power box. So it will come on with all the stepper drivers,
but spindle power is soft started by enabling the machine from F2,
takes 3 seconds to get full power.  And I don't trip a 30 amp
breaker charging the supplies caps.

But is it safe to apply the high voltage motor power to the
pwm-servo amp IF for some reason the interface is powerless and
its 12 volt supply is off. This will put full motor power at
pins-1-2, with no logic power on pin 6.

Is that safe, or will it let some smoke out and kill all the local
kittens? I could rig a relay, or better yet, move the SSR +
terminals to the 12 volt supply, better yet disable that in hal if
the 12 volts isn't there by changing the sserial com mode so it
will send an a/d output back to lcnc.  Thats slower of course but
I'll check it out.

Thanks Jon.

Correction, to clarify what I am doing to me when I take a copy to the

I believe I've figured out how to squeeze the pwmservo's controls
into 1, 5 pin plug.

Connecting a ground to pin2 and pin4 on the servo hooks up a - for the
optos for pwm and dir. 1 wire. The shields in a two pair cable, use
pin 3 in the GS12-5 connector.
Feed regulated 5 volts to spindir+ right on the 7i76. no cable wire
Feed spindir- to servo pin 3, direction+.  2nd cable wire, will pullup
servo direction line.


To PCW:

But I got shaky making up that cable and connector and inadvertantly made
a solder blob short between spindir- and ground, with 5.11 volts on
spindir+.  And spindir- isn't coming on even with the short removed now.
FWIW, all 5 of the contacts in this plug are in about a 5.5mm circle.
Next panel I'll use the GS16-5 plug, bigger and far easier for this old
man to work with.



Yeah you can definately fry the OPTO transistors by driving into shorted load




I've fixed the short, but may have toasted that driver chip. If it was
ptc protected, does it take a full everything off including the computer
to reset it, and how much cooldown time. Its had power but has not come
back in around 30 minutes. No heat either.

So sock it to me Peter. If its toes up for good, I can put the 2nd card

Yes its fixable  just needs a TLP127 OPTO and careful work with a SMT hot air 
gun...

Which 
But thats not done yet, I finished up the home rewiring, and I may be 
getting a leetle bit schmardter.  As I'm  hooking things up, and getting 
sserial fails and shut down notices in the shell I'm running lcnc from. 
So when I got the last one  back together and it  didn't work, a 
shutdown left those messages on screen  Restarted lcnc and it works.

So ATM I have a reserved input for the probe, and the steppers to wire 
step-dir sigs to, and I think put the probe on a 5 pin plug thats not 
busy.

Then I should be ready to smoke test it by late tomorrow.. So far I've

I took ohms readings on it at the card input point, figured the shield of 
the existing was ground, and I faintly recalled the power lead to the 
omron was the 5 volt supply and it would be a lower ohmage. That left 3 
unidentified leads, two of which had nearly identical ohms to ground 
while the third was obviously different as it comes from the old optical 
index on the spindle, not from the omron on the motor by way of a couple 
rs455 receivers in a little box in the middle of the encoder cable.

My cable has two shielded pair, a blk-wht and a blk/red.  So I hooked the 
shields to ground, the red wire to 5 volts, the blk wires to enca+ and 
encb+ and the wht to idex+. I even got lucky and had the black wires 
correct, the raw count moves in the right direction when the spindle is 
turned by hand.

So that should be solved, then I read the comment about wiring limits etc 
on page 14, and assumed it also applies to home switches. Which doesn't 
match my current setup, so I'm in the early stages of putting in new 
switches and wireing it up according to that comment on p

This is solved and it looks like I can excise that other stuff from the 
hal file.

Now, re a lack of response at the actual outputs 15 and 14.

I did a setp to set invert true, made them come on when they should have 
been off so I setp them to false, and now they are working as desired.

But they weren't working before I setp'd those 2 output-inverts to 
anything. I can see my halfile growing another 50+ lines, but so far 
I've not yet had to invert an input, mostly because what I've used so 
far (spindle gearshift tally's) is on the SainMmart bob and coming in 
thru p2 on the 5i25.  But the home switches will have to be on the 7i76.  
Thats probably another differently painted horse...

Onward and upward, to encoder inputs (I hope) But the old BoB got in the 
way, so all 4 steppers step and dir's are now on are now on one terminal 
strip, waiting for me to bring in the cables. Small power supplies can 
leave as this new box can supply all that. I can bring in two steppers 
per cable, and use the 5th connection on one of them to ship in the 5 
volts for the drivers + terminals. That gets me down to two cables and 
connectors for all 4 axises. That might leave me enough to run a tool 
changer.

I've figured out the 5 volts and grounds for the encoder but I have to 
power it up to decipher which of the other 3 wires is which. Ditto the 
home switches.  That was such a birds next inside and around the old Bob 
that it just had to go.

And by the time I'd made two trips to the store because the larder was 
getting low, and fixed dinner for the missus, I'm all in but my 
shoelaces.  Tomorrow is the next day to work on this.  Anything else in 
the odd dept. I need to know?  Home switches are all closures to ground, 
do I need to put pullups on the 3 inputs, or do they supply what they 
need?  Or, since their grounds are isolated from the machine frame, 
should I put 5 volts on that ground and watch for a true coming out?

Thanks for your patience Peter.

Re: [Emc-developers] 7i76 vs spinout signal

[Peter C. Wallace]

the nuts on those connectors which are below the boards in this box.

Now in the next step of wiring this up I have a pair of 40 amp SSR's, 
with 5.11+ on both + terminals of the SSR's, and am using 
hm2_5i25.0.7i76.0.0.outputs 15 and 14 with the idea that turning them on 
will ground the -terminals, enabling the SSR's in sequence, when the 
first one is enabled, power is applied to the stack of toroids thru a 50 
ohm 200 watt resistor the start chargeing the filter caps, 3 second 
later an identical signal is sent to hm2_5i25.0.7i76.0.0.output14 which 
bypasses the 50 ohm resistor, enabling the spindle psu at full power.


I can see, with a halmeter that the signal is sent to those output pins.

But they aren't turning on to sink the - pins of the SSR's.  They 
regardless of the halmeter state, stubbornly sitting at 4.66+ which 
would be about what I'd expect to see when I measure to ground/common 
with a 10 megohm input DVM from the - terminals of the SSR controls. Not 
enough current flowing thru the meter to tickle the SSR's of course. I 
am wired to the last and next to last at the upper end of TB5 which the 
docs say is output15 and output14. Field power on the orange connector 
is 12.2 volts positive on pin 1, and negatives are wired common between 
pin 8 of the orange connector and pin 24 of the 4 pin header to its 
left.





Another common issue can be that you are not using the field power common for 
the load common (note that the field I/O is galvanically isolated from logic 
power so the load power common must connect to the field power (orange 
connector) common

I did not find that in my testing, Peter. Neither ENA- was pulled up
to the +12 volts on ENA+, nor was DIR- pulled up to the +5 volts on
DIR+, until I gave it a non-zero spinout. In my testing, no power was
applied to tb4,1-3 because the intent is to use the 2nd pwmgen as the
input to jon's servo amp in this instant build. I will use it with the
vfd in the 6040 build that I bought the 2nd 7i76d for. So I was forced
to use the relay on a sainsmart bob to switch the ena to the pwm-servo
amp and use a timedelay module to delay everything else until the
relay was solidly closed.

Is there some other magic I missed?  Humm, maybe, I had not learned
about the params that needed set according to "man 9 sserial" until
yesterday. IMO, this should have been mentioned in the downloadable
doc for the 7i76 but is not. They now are being set, so I'll retest
and advise today.

Those aren't accessible to a halmeter, so I have to use a dvm (or a
scope) to verify. And I was reading  a wandering 60 millivolts to
ground at those terminals.

Thanks Peter.

However, motion.spindle.is-on is false if spindle speed is zero. Perhaps this 
is a Hal thing?

I just read it again, top to bottom and back up. None of this stuff is
in it, nor is there any reference to reading the manpage for sserial.

So it does, but haveing no reference to it in the doc, I hadn't read
it until now. It also states theres a high likelyhood of its being
permanently out of date.  And it makes zero mention that ENA and DIR
appear to be activated ONLY when when spinout has valid non-zero data.
That might work for a vfd but not for a pwm-servo such as Jon sells.
The way its worded, ENA and DIR appear to be straight thru from input
to output isolated controls, which would make them 100% useful. But
because they aren't activated until spinout has valid non-zero data,
the ENA is of zero use to me. That amp must be enabled, then pulsed to
charge the gates properly before the data from the pid.out arrives at
the pwmgen.1.value pin to start its generation of pulses. I do have a
method worked out that should work, using the otherwise mounted for
its looks, relay on the SainSmart BoB. Driven by p2 of the 5i25 using
a special bitfile Peter sent me which puts a 2nd pwmgen on the P2
connector since the first one goes to /dev/null in the 7i76d. I may be
able to get that wired up tomorrow, but I am making all this hookup
hardware as I go. From a 150 foot spool of wire, and a bag of GS12-5
connectors. Darned near too small for these getting a little shaky old
hands.




Thats not quite true, The 7I76 DIR output is a completely independent
output bit and ENA must be present for the analog output to work, that
is analog out is dependent on ENA but not the other way around.

I did not find that in my testing, Peter. Neither ENA- was pulled up to 
the +12 volts on ENA+, nor was DIR- pulled up to the +5 volts on DIR+, 
until I gave it a non-zero spinout. In my testing, no power was applied 
to tb4,1-3 because the intent is to use the 2nd pwmgen as the input to 
jon's servo amp in this instant build. I will use it with the vfd in the 
6040 build that I bought the 2nd 7i76d for. So I was forced to use the 
relay on a sainsmart bob to switch the ena to the pwm-servo amp and use 
a timedelay module to delay everything else until the relay was solidly 
closed.


Is there some other magic I missed?  Humm, maybe, I had not learned about 
the params that needed set according to "man 9 sserial" until yesterday. 
IMO, this should have been mentioned in the downloadable doc for the 
7i76 but is not. They now are being set, so I'll retest and advise 
today.


Those aren't accessible to a halmeter, so I have to use a dvm (or a 
scope) to verify. And I was reading  a wandering 60 millivolts to ground 
at those terminals.


Thanks Peter.


The 7I76 spindle ENA and DIR outputs are independent of the analog value
of spinout, (though the analog out is forced to 0 if spinena is false)
is it possible you have a wiring error?

The 7i76 manual lacks anything like such an explanation for the

the doc file I am looking at for about 3 months now.

Because it??s a double precision floating point.

Are you reading the 7i76 manual or just the LinuxCNC docs?

Aha! Thanks Peter, due to an Oldtimers attack, I never thought to check 
the halmeter's params menu. Now it all falls into place.  Those are 
relatively small numbers, set in the .ini file for the G0704, excerpt 
minlim which doesn't apply with a pmdc motor, and the way I'm wiring it 
I don't think the inverts will be needed.

However, I'll need an ENA active separately on the G0704. Can that be 
done by inverting a field output? In the sequence of applying signals to 
srart and boot the pwm-servo, I need the +12 volt on its enable before 
its booted, in order for the boot to work.  And since its a d suffix, 
ENA- looks like the only way.

I think I have something else in that path due the the head gear shift in 
the G0704, but I get the idea now.  There's a pid.s in that setup with 
buckets of Pgain. Not needed in the vfd version since it will never cut 
threads anyway. So I'm not 100% convinced I need a spindle encoder on 
the 6040.

Anyway, I am slowly wiring it up.  And finding the GS12-5 connectors are 
a bit small for my getting shaky hands to reliably solder to. But I'm 
getting there. Dinner got in the way for tonight though. And I could use 
a longer backshell, but thats solvable on the next one. Timeing I'll 
have to check with halscope.  Fun & games. What I really need is an ENA 
I can drive ahead of time, a millisecond or so, or possibly recompile 
the boot module for a much longer chain of start pulses.  That might do 
it.  But next is getting the spindle power supply startup sequence wired 
up. That may require I work over a length of 1/2" conduit to fashion a 
13mm socket on one end of a foot of it so I can reach in under the pcb's 
and tighten the nountings nuts.

Thanks for the help.

Approx -1.8 x 10^308 to  +1.8 x 10^308

Because it’s a double precision floating point. 

Are you reading the 7i76 manual or just the LinuxCNC docs?

It would be very, very, very, nice if that was mentioned in the docs, 
Andy. Not a dot for an i or the crossbar of at. So I automaticly assumed 
it was a spinx1 in function.

But whats the range of spindle speed requests that are valid in that 
case.  I currently, for testing, have the motors idle speed set to 2, 
faster than the normal .1 that my hal file uses when neither gear shift 
switch is closed because they aren't wired up yet. This results in 
nearly full scale for a value of 49 sent to the pwm, giving a 99.9% duty 
cycle at the pwmgen output because the pid.s.Pgain is 20.  And on the 
GO704 using one of Jons pwm-servo's, I will/am (not wired yet) using the 
pwmgen.1.output sent to p2-gpio-26 as the pwm for that servo amp. But I 
still need functioning ENA- and DIR- so I've got to feed spinout 
something too else they don't work. Whats currently coming out of 
pwmgen.1 has already been calibrated for the GO704 and its pwm-servo 
driving the spindle.

But on the 6040, with its bastard 120 volt vfd, I'll need this 7i76's 
spindle setup from tb4-1-2-3.  But surely it can't deal with being sent 
a value of 24,000, or even half that at 12,000 for half speed of that 
spindle. For that to work there has to be a scale converting the rpms 
requested to something that ranges from 0 top 10 volts at the equ to the 
arm of the pot at tb4-2, where 1 and 3 are the com and 10+ or 12+ volt 
lines from the vfd.

So how is that "scaleing" between 24k rpms when the motor is to be wide 
open, and a full scale output of 10 volts to the vfd to be accomplished 
when I build this same interface for the 6040?  I rx'd the 2nd 7i76d 
yesterday Peter, but haven't unpacked it yet. One track mind strikes 
again. Oldtimers?

==

Much of the same hal file will be used, with only the gearshift stuff 
excised since that spindle has no gearshift. Nor will it have an encoder 
unless I can rig an IR optical off the wrench flats of the motors chuck.  
That will have to co-exist with the tool changer wrench if I build the 
hack-a-day tool changer. But I've already found the needed carousel spin 
is at least a full turn just to break a collet loose with the collets I 
have and only one nut so far, so thats discouraging. But its still a 
cute idea. Perhaps a ratcheting motion could be programmed, turn the nut 
1/3rd turn, lift it out of the socket, rewind the carousel and xy, drop 
it back into the gator socket, turn it another 3rd turn, wash rinse 
repeat as needed. Reverse to tighten but spring load the holding wrench 
away from an "its tight switch" so we don't loose the homes from 
slipping the motors a step or 70. Perhaps 2 switches in case its too 
tight, in which case leave the locking wrench in place, but lift it 
clear of the socket so a hand wrench can be used on the nut to break it 
free.  Use an M30 pause for that.  On a 6040, its big enough the 
carousel could have 8 pockets, and the larger diameter would give the 
motors a better chance of getting it done with less stress on the motors 
and screws.

Thinking out loud...  And all dependant on getting the vfd to respond to 
the DIR- to work, so the motor could be used to drop the nut and pick up 
the next one. In fact, it runs in reverse just fine if its 
miss-configured. I found that quite by accident while trying to make it 
work from the pc with only a 5 volt pwm, but it seems to need a 10 volt 
pwm, applied to a different input terminal.  But thats another subject 
line for Later. :)

Thank you Andy.

Cheers, Gene Heskett

Subject: [Emc-developers] 7i76 vs spinout signal

Can someone please explain to me, who is used to using a spinx1 for the
pwmgen output to analog voltage conversion, just how in tuncket the 7i76
works? I just now found out, when I tried to redirect a 5i25 pwmgen
output pin and found from the error  msg as it died, that
hm2_5i25.0.7i76.spinout is a float input!

In Other Words, pwmgen.0. in the 5i25 is driveing /dev/null.  So I fed
the hm2_5i25.0.pwmgen.0.value to hm2_5i25.0.7i76.spinout and can now
read it there with a halmeter.  But I've no clue what sort of a float it
wants to use the full voltage range of tb4's spindle- to tb4's spindle+
at tb4's spindle-out.

The document on the 7i76 seems to be totally mute on this. Can some who
knows please explain?

To say I am bumfuzzled at this revelation is putting it mildly if this
does indeed bring the ENA and DIR outputs on tb4 to life, which are not
responding with spinout at 0.. I'll have to recalibrate scales
and gains at several locations in nearly a 800 LOC hal file.

Thanks all.

The 7I76 spindle output should not be too different from a PWM setup
There are three pins related to spindle control

7i76.x.x.spindir
7i76.x.x.spinena
7i76.x.x.spinout

and 5 parameters

7i76.x.x.spindir-invert
7i76.x.x.spinena-invert
7i76.x.x.spinout-maxlim
7i76.x.x.spinout-minlim
7i76.x.x.spinout-scalemax


Typically the maxlim and scalemax parameters are set to the maximum spindle 
RPM, and the minlim parameter is set to 0. This scales the analog voltage so 
full scale RPM is full scale voltage (100% of SPIN+)


The 7I76 output is unipolar so normally its linked to motions spindle speed 
speed-out-abs pin

The 7i76 has a (serial controlled) digital potentiometer.  You just pass it a 
the spindle speed you want and the two resistances change. You wire it exactly 
like a potentiometer and send it a number. 

The Spinx1 takes a PWM input and does much the same at the output. 

Wiring a 7i76 to a spinx1 is unlikely to work.
