The KBIC is NOT isolated from the mains, there is NO transformer inside of it. There is no need for it to be and it would just add to the cost to do so. Since they have made them for 25 years or so I guess the design is solid. With a VFD you have a completely different type of speed controller. It takes the incoming AC, rectifies it to DC, then switches the DC quite quickly to produce AC again at the desired frequency. The control circuits on most VFDs are isolated but you should always RTFM to be sure. Jeff Birt Soigeneris.com From: mach1mach2cnc@...

Hi,
Without exception (from my experience to date ) all VFD's have a 10Vdc supply
that is used as a power supply for attaching a manual speed potentiometer.
This 10V supply is used to provide power to the G540 VFD pins 7 and 9.
If you are controlling a DC motor controller that does not provide such a
supply you will need to use an auxillary dc power supply of a voltage that
suits you spindle speed controller's input specification.
NOTE: This auxillary supply NEEDS TO BE AN ISOLATED SUPPLY!!!! as the 0v
reference for this supply may be near main potential voltage. 110/220V. If
you don't use an isolated supply you may end up destroying your motor
controler, cnc controller, PC and yourself.
If you don't understant the above then DON'T attempt to wire it up as the
voltages involved may kill you. Also, any work involved with Mains Voltage
needs to be done by a qualified electrician.
Cheers,
Peter

Subject: Re: [mach1mach2cnc] VFD and PWM and G540
Hi,
No, the G540 pins 7 and 9 do not output a 12V supply on their own.
The G540 generates an isolated control voltage on pin 8. The amplitude of
the voltage is voltage is a percentage of the voltage that is supplied to
pins 7,8 of the G540. The percentage is derived from the Mark/space ratio of
the PWM signal from Mach3 that is present of pin 14 of the G540's DB25
connector.
So, if the duty cycle (mark/space) ratio is 25%, then the voltage output on
pin 8 of the terminal block will be 25% of the voltage you supply across
pins 7,9. In this example, if you supply pins 7 and 9 with 10V, the G540
will generate 2.5V on pin 8.
If you supply pins 7 and 9 with 12V, the G450 will generates 3V on pin 8
when
Mach3 outputs a PWM with a duty cycle of 25%
Note, the recommended max voltage supply across pins 7,9 is 12Vdc.
Cheers,
Peter

Re: Where are we in Mach 4
So I went a little further in the
configuration(set up my pins/signals in the ESS), shut down and reran Mach4,
and now, when I attempt to get back into the ESS Plugin configuration, it
highlights the "Configure" button and then just sits there.
?
If I then close the Plugin Config window,
and close Mach4, the Mach4GUI process stays up.
?
Looks like this PC may be more of a help
than we thought.......

Hi Brian:
?
I posted on the Machsupport Forum about this. I am using an ESS,
but before I even et to that point, things go haywire.
?
-After install of Mach4, when I try to run it, it says that
"the application cannot run because the configuration is incorrect".
Based on a tip from someone on the Machsupport forum, i installed Gearotic, and
then manually ran the VC++ redistributable install from Gearotic, and was then
able to run Mach4GUI. But after running the GUI a few times, it started to not
appear on teh screen, that is, there would be a process called Mach4GUI, but I
would never see it on my monitor.
?
-So in that state, I could run wxmach, and it does appear on my
screen, but as soon as I try to setup the ESS plugin, Mach4 crashes.
?
?
?
Andy what seems
to be the issue on your machine?
What are you running for a device?
Thanks
Brian
Geez, Ozzie....I'd be happy if I could just get Mach4 to show up on
the screen more than once per reboot.....:)
?

Hi Brian,
Please tell us where we are in the grand scheme
of Mach 4.?
Can we expect a package comparable to Tormach's
new conversational version of Linux for both mill and lathe? Of course I own
the Mill Wizard, but that does nothing like the Tormach program for lathe.?
Will we see Mach 4 with probing sequences
built-in, set-up?
Many of us bought on faith, please let us in on
what to expect, or is this it.
Thanks,
Jerry "Ozzie" Pryor

i checked the manual for my KBIC speed control and it is clear that
what you describe is the case. i also measured from the pot to

If you use a multimeter to measure the voltage across the

Touch the wire that is the 0V side of that measurement and

Using win 7, Mach3 Turn, gecko g540 and uc100 ? Just starting to use Turn and ran into something I don’t understand (there’s a lot I don’t understand). ? When I issue a G03 command it seems to multiply the feed rate by a factor of ten.? ? g01 f5 x0.325 z0.050 x0.300 g03 x0.200 z0.225 i0.000 k-0.02500 ; just zips around the arc! g01 z0.275 g0 x0.3625 ? Shouldn’t it run at the same feed rate as the G01? ? TIA ? RT

Sounds good, will buy the DC-03 when i decide i need program
control. need to get the motor working first and determine if i can
get a better finish by varying the speed for different cuts. i am
trying to produce a part that does not require sanding so i have to
fiddle with every rough and finish and cleanup cut.

Hi Spencer,
One or both relays on the DC-03 can be controlled
separately from the spindle
control if desired.
In normal use they are controlled via the M3 and M4
commands on the Mach3
spindle setup tab, but you could use them for other uses
as well.
If you wanted to you could control two VFDs with the one
DC-03. You could;
1. Connect VA+ to the +10V terminal on one VFD
2. Connect AVgnd to the 0V terminal on both VFDs
3. Connect the AVout to the Control voltage input on both
VFDs
4. Connect Relay one to the FWD or RUN terminal on one VFD
5. Connect Relay two to the FWD or RUN terminal on the
other VFD
You can then use M3 to run on one VFD and M4 to run the
other. If you have
maximum spindle speeds on the two spindles, use the pulley
selection so that
pulley 1 is used on the first spindle and pulley 2 on the
2nd.
The DC-03 can also be used with spindles that use a +/-10V
control voltage
inputs where a -ve voltage reversed the spindle direction.
The two relays can
be wired so that when a M3 is issued the DC-03 presents a
positive voltage to
the spindle controller, and then presents a -negative
voltage to the
controller when an M4 is issued.
By having indepentant control of the two onboard relays
they can be used to
implement a wider range of control variants.
Cheers,
Peter

Hi Brian:
I posted on the
Machsupport Forum about
this. I am using an ESS,
but before I even et to that
point, things go haywire.
-After install
of Mach4, when I try to run
it, it says that
"the application cannot run
because the configuration is
incorrect".
Based on a tip from someone
on the Machsupport forum, i
installed Gearotic, and
then manually ran the VC++
redistributable install from
Gearotic, and was then
able to run Mach4GUI. But
after running the GUI a few
times, it started to not
appear on teh screen, that
is, there would be a process
called Mach4GUI, but I
would never see it on my
monitor.
-So in that
state, I could run wxmach,
and it does appear on my
screen, but as soon as I try
to setup the ESS plugin,
Mach4 crashes.
Andy what
seems
to be the issue on
your machine?
What are you running
for a device?
Thanks
Brian
Geez,
Ozzie....I'd be
happy if I could
just get Mach4 to
show up on
the screen more
than once per
reboot.....:)
Hi Brian,
Please tell us where we are in the grand
scheme of Mach
4.
Can we expect a package comparable to Tormach's
new
conversational
version of
Linux for both
mill and
lathe? Of
course I own
the Mill
Wizard, but
that does
nothing like
the Tormach
program for
lathe.
Will we see Mach 4 with probing sequences
built-in,
set-up?
Many of us bought on faith, please let us in
on what to
expect, or is
this it.
Thanks,
Jerry "Ozzie" Pryor

Re: Where are we in Mach 4
Hey you can do as many great things as you like but its support is
getting to be limited and we picked what worked best for us.Mach4 is
cross platform and so is Lua. Everyone that has taken the time to
work with Lua has seen why we use it, It is SO much faster!
From Wikipedia:
"Mainstream Support for Microsoft Visual Basic 6.0 ended on March
31, 2005. Extended support ended in March 2008.
In response, the Visual Basic user community expressed its grave
concern and lobbied users to sign a petition to keep the product
alive.
Microsoft has so far refused to change their position on the
matter."
Thanks

you haven't worked in Excel/word/Project etc much have you?
I have a macro at work, nearly 40 modules now, (somewhere around

I've written MAJOR systems in VB .... (started back in the

real-time automation robotics in a manufacturing and test

I know I know...why VB?.... because it was easy for a bunch of
non-programmer type engineers to hack numbers and setting to tweak
stuff over the years.
VBA can do everything VB can do....anything in a DLL can be called
as in VB. It's all a matter of how much of the API you

No I don't think I was over the top.
If you use a multimeter to measure the voltage across the manual speed potentiometer of a KBIC-120 controller you will get a reading around 10-15V.
Touch the wire that is the 0V side of that measurement and you will get a main voltage shock. Connect that 0V wire to the 0V of your breakout board and you will release a lot of magic smoke.
On the KBIC, the 10V terminal(P3) sits at 115V, the 0V terminal sits at around 100V.
So yes, the 10 volts can kill you.

Hi,
Without exception (from my experience to date ) all VFD's have a 10Vdc supply
that is used as a power supply for attaching a manual speed potentiometer.
This 10V supply is used to provide power to the G540 VFD pins 7 and 9.
If you are controlling a DC motor controller that does not provide such a
supply you will need to use an auxillary dc power supply of a voltage that
suits you spindle speed controller's input specification.
NOTE: This auxillary supply NEEDS TO BE AN ISOLATED SUPPLY!!!! as the 0v
reference for this supply may be near main potential voltage. 110/220V. If
you don't use an isolated supply you may end up destroying your motor
controler, cnc controller, PC and yourself.
If you don't understant the above then DON'T attempt to wire it up as the
voltages involved may kill you. Also, any work involved with Mains Voltage
needs to be done by a qualified electrician.
Cheers,
Peter

Subject: Re: [mach1mach2cnc] VFD and PWM and G540
Hi,
No, the G540 pins 7 and 9 do not output a 12V supply on their own.
The G540 generates an isolated control voltage on pin 8. The amplitude of
the voltage is voltage is a percentage of the voltage that is supplied to
pins 7,8 of the G540. The percentage is derived from the Mark/space ratio of
the PWM signal from Mach3 that is present of pin 14 of the G540's DB25
connector.
So, if the duty cycle (mark/space) ratio is 25%, then the voltage output on
pin 8 of the terminal block will be 25% of the voltage you supply across
pins 7,9. In this example, if you supply pins 7 and 9 with 10V, the G540
will generate 2.5V on pin 8.
If you supply pins 7 and 9 with 12V, the G450 will generates 3V on pin 8
when
Mach3 outputs a PWM with a duty cycle of 25%
Note, the recommended max voltage supply across pins 7,9 is 12Vdc.
Cheers,
Peter

Hi Spencer,
One or both relays on the DC-03 can be controlled separately from the spindle control if desired.
In normal use they are controlled via the M3 and M4 commands on the Mach3 spindle setup tab, but you could use them for other uses as well.
If you wanted to you could control two VFDs with the one DC-03. You could;
1. Connect VA+ to the +10V terminal on one VFD
2. Connect AVgnd to the 0V terminal on both VFDs
3. Connect the AVout to the Control voltage input on both VFDs
4. Connect Relay one to the FWD or RUN terminal on one VFD
5. Connect Relay two to the FWD or RUN terminal on the other VFD
You can then use M3 to run on one VFD and M4 to run the other. If you have maximum spindle speeds on the two spindles, use the pulley selection so that pulley 1 is used on the first spindle and pulley 2 on the 2nd.
The DC-03 can also be used with spindles that use a +/-10V control voltage inputs where a -ve voltage reversed the spindle direction. The two relays can be wired so that when a M3 is issued the DC-03 presents a positive voltage to the spindle controller, and then presents a -negative voltage to the controller when an M4 is issued.
By having indepentant control of the two onboard relays they can be used to implement a wider range of control variants.
Cheers,
Peter

We have a server here
that we use... the package is called screen connect.
Sure, Brian, I could get you in there-what remote software do you
prefer?

Hello Andy,
Is there any chance I could remote into that machine to see if I can see what
is going wrong? Very sorry I didn't see that on the forum, I have been working
on code and testing, My forum time is very limited and I count on direct
contact so please feel free to contact me directly if you have an issue! I want
them fixed!!!!
Thanks
Brian
Hi Brian:
?
I posted on the Machsupport Forum about this. I am using an ESS,
but before I even et to that point, things go haywire.
?
-After install of Mach4, when I try to run it, it says that
"the application cannot run because the configuration is incorrect".
Based on a tip from someone on the Machsupport forum, i installed Gearotic, and
then manually ran the VC++ redistributable install from Gearotic, and was then
able to run Mach4GUI. But after running the GUI a few times, it started to not
appear on teh screen, that is, there would be a process called Mach4GUI, but I
would never see it on my monitor.
?
-So in that state, I could run wxmach, and it does appear on my
screen, but as soon as I try to setup the ESS plugin, Mach4 crashes.
?
?

Andy what seems
to be the issue on your machine?
What are you running for a device?
Thanks
Brian
Geez, Ozzie....I'd be happy if I could just get Mach4 to show up on
the screen more than once per reboot.....:)

Hi Brian,
Please tell us where we are in the grand
scheme of Mach 4.?
Can we expect a package comparable to Tormach's
new conversational version of Linux for both mill and lathe? Of course I own
the Mill Wizard, but that does nothing like the Tormach program for lathe.?
Will we see Mach 4 with probing sequences
built-in, set-up?
Many of us bought on faith, please let us in
on what to expect, or is this it.
Thanks,
Jerry "Ozzie" Pryor

Mach3 can be set up to generate PWM on any pin that you like.
This is done with the dialog at Config > Ports and Pins > Motor
Outputs. Fill in the desired PWM pin under Step for the Spindle
Motor. Then go to the Config > Ports and Pins > Spindle Setup
and look for the Motor Control section and put a check mark in
the Use Spindle Motor Output and the PWM Control boxes. You
may also want to configure the Relay Control and the Flood/Mist
Control (as an alternate way to control the second spindle). This
is a two step process. After you assign an Output number, go
back to the Output Signals page and assign an actual pin to the
outputs that you used.
The traditional way to control modern VFDs with analog inputs is to
use an interface that converts the PWM signal into an isolated
analog voltage. Our PMDX-107 is one such device, but it is not that
difficult to build your own. The PMDX-107 does not use a separate
control signal from Mach3 to turn the spindle on and off. It monitors
the PWM to decide when to turn the spindle on. Mach3 turns the
PWM completely off if the M5 spindle off command is issued.
Running two spindles will require that you take direct control of the
spindle on/off signals or move the command for the second spindle
to something other than M5 if you plan to use a PMDX-107 for the
first spindle. I would recommend that you use the Flood/Mist
controls as a way to run the second spindle.

i read it all but it is for an air cooled spindle and the most
important point relates only to air cooled fans etc. mine is water
cooled so i don't have to worry about that aspect. i assume you run
the cooling water all the time the machine is running even if the
spindle is stopped.
i still need to know the best way to control the speed if i decide i
want to. still don't know if mach3 will pwm the step or direction
pin assigned to spindle in ports and pins if i choose pwm control in
spindle setup. if so i just need to connect an FET driver to a
voltage source to get what i need for the voltage following input of
theVFD
still need to know if it is possible to have one spindle PWM
controlled and the other one on/off without PWM control.
?
and you will then be completely au fait
with all aspects of the VFD etc

Re: Where are we in Mach 4
Almost all of my g-code is created using a VBA macro in AutoCAD.
VBA's not dead, or going away.

VBA limited?
you haven't worked in Excel/word/Project etc much have you?
I have a macro at work, nearly 40 modules now, (somewhere around
25,000 lines?)? autol oads when I auto-start Outlook first thing
in the morning. Processes/catagorizes my email, manages schedules,
auto responds to priorities, training programs, auto formats
reports, ...about 35 daily functions now.
I've written MAJOR systems in VB .... (started back in the
original DOS version then coverted/ported to Windows) controlling
real-time automation robotics in a manufacturing and test
environment.
I know I know...why VB?.... because it was easy for a bunch of
non-programmer type engineers to hack numbers and setting to tweak
stuff over the years.
VBA can do everything VB can do....anything in a DLL can be called
as in VB. It's all a matter of how much of the API you
understand/or are familiar with.???? :-)

I guess we had better tell Microsoft that they don't
support VB. ??; -)
It is in the 2015 VS preview download.?
I am guessing you mean VBA which was pretty limited.

Re: Where are we in Mach 4
Start out by saying i don't consider myself even near the same league as Brian, Art or the others that program. ?Just a mere hack.
Like yourself I have used VBA although in the DOS days was doing LISP. ?Most of my experience was in Autodesk products but have done some of the Microsoft office products.
Last summer wrote Komo and Onsrud posts in Alphacam.? Alphacam posts are VBA. ?Alphacam installs the VBA patch when you install it.
Currently I spend most of my time in VB.net, but work some in C# and C when there is no other choice. Alway forget the dang semicolon... Learning Python currently. ?Fun project with Raspberry Pis, Barcode scanners and PLCs.
VBA is limited comparatively to other programming languages including VB, because of the API that you have to work with.
A project from a year or so ago.
Have the user select a zipped file, extract the files that are within. Then update a data base and print out a Win report form based on some of the data in one of the files. ?
Add a worksheet to that days excel workbook add the values from another file into the newly created sheet.
Then finally fill out a PDF template from a combination of the files along with some user input and then email the resultant PDF to a selected email as well as allow the user to print if they want.
I imagine you could do it in VBA but using .Net or LUA is a whole lot easier.

Excellent, what type of power supply can I use for this as it appears a
second power supply is required
Thanks

Subject: Re: [mach1mach2cnc] VFD and PWM and G540 Hi, No, the G540 pins 7 and 9 do not output a 12V supply on their own. The G540 generates an isolated control voltage on pin 8. The amplitude of the voltage is voltage is a percentage of the voltage that is supplied to pins 7,8 of the G540. The percentage is derived from the Mark/space ratio of the PWM signal from Mach3 that is present of pin 14 of the G540's DB25 connector. So, if the duty cycle (mark/space) ratio is 25%, then the voltage output on pin 8 of the terminal block will be 25% of the voltage you supply across pins 7,9. In this example, if you supply pins 7 and 9 with 10V, the G540 will generate 2.5V on pin 8. If you supply pins 7 and 9 with 12V, the G450 will generates 3V on pin 8 when Mach3 outputs a PWM with a duty cycle of 25% Note, the recommended max voltage supply across pins 7,9 is 12Vdc.

Hello:
Can anyone tell me how the PWM signal comes out of Mach?. And if you
have made connection correctly from G540?. Pin 7,8 and 9 are connected
to VFD, Does pin
7 and 9 put out 12V on their own?
