Generic Spindle interfaces, I/O boards, Misc boards and panels / Re: Setting up PMDX-107/VFD with PMDX-126 and relays

Thanks so much 12strings
...good info about the specific criteria related to ESS setup.
Through trial use of the MDI, I found an acceptable work-around (at least for the time being).

It turns out that the following G-Code syntax will shut down the spindle at the end of an executed program.

G0 ......(program's ending lines)
M5
S0
M30

The "M5" has to be on a line separate from and ahead of the "S0" (S-zero) command.

As to your questions about the LED indicators;
yes, they go on when triggered at the program's outset and shut off when the above command protocol is followed.
(Intensity looks as though it changes with speed (RPM) commands; (which commands I've had no issue with).
...go figure...
However, I'm glad it's operational and that its operation at least resembles the intentions of the Warp9 folks; (sorta)
I'll delve into this issue with Warp9 (and perhaps Newfangled) when time permits.
Unless of course you have some other ideas.

Thanks

Hello Again
Sorry for such a late response.........Life
The new setup runs well, in spite of the glitch, I'm really quite pleased.

The spindle.... Just doesn't seem to like an M5 command.

Responds to G-Code M3 with S####
Responds to G-Code M7 and M9 (Mister)
Responds to any written mid-code (as well as Mach4 dashboard) change in spindle RPM
Responds to M3 S#### executed within the MDI

Herein is the exception.....
Responds only to a separate MDI "S0" (zero speed) command outside of the executed G-Code in order to shut down spindle.
JP1 = To run on pin 1    (K1 relay not used)
JP2 = To run on pin 14  (K2 misting relay; running great)
ESS Motion Control

You pointed out:
"PMDX-107: Normal mode, SSRs are "run" and "direction", ignore "charge pump OK" signal, fast PWM filter and 10V output range."
I have set these parameters accordingly.

I've noticed Plug-Ins for Mach4 when 107 is paired with the Smart-Bob boards to rectify M3, M4, M5 etc issues;
does that also apply here?

Thanks again 12strings and sorry for my late response.
I hope I have properly addressed your questions to me.
Walt

Hi...new poster (I think)
I too am having a somewhat similar situation, but yet also a little unique.
I’m utilizing a PMDX-126 with the DIP configuration: 1-8 all on except 7 is off;
 married with the PMDX-107 with its DIP configuration: 1,2,5 & 6 are off, 3 &4 are on.

My VFD (Teco) is solid; utilizing an toggle (by relay or SS) and speed (RPM) by analog input (10VDC)
All has worked well under a different BOB and controller.
Also, when I push the 107’s self contained “Test” button, everything works fine.
However, when I manually click the spindle button on my Mach4 interface or enter the appropriate
code in the MDI (stating speed) my “spindle on” (PMDX-107 out-pins, 4 & 5, I get only a quick energization
at k1 (relay and light) and of course the light at pin 5, then nothing until I make a second attempt at starting
the spindle.
Again, pushing the self-contained “Test” button on the 107 has the spindle performing as it should.

...not sure if I was to post here (couldn’t find where else to go)
Thanks in advance....
Walt
