c-11g to mach3 to speedmaster vfd need help

[m8kingit]

I'm in the final stage of the redo of my cnc master's mishap controller.
I'm installing a c-11g board , however i can't find enough documenttaion to finish hooking up this vfd I have a shematic from the vfd high looks pretty easy, however, I'm not finding what i need it mach3 to coordinate the hookup
Mu guess would be the two relays on pin 1 and 16, however, i didn't see any here in mach 3 where to coordinate where they were hooked up.

I do see where the spindle is suppose to be configured to pin 14 step and 8 dir, but that's in the cnc 4pc documenttaion and that's as far as it goes.

In macg there is a setting for the ccw and cw but it ask for pin 1-6, it doesn't say anything about 16.
I'd also like to know if mach 3 will control the speed thru 14 and 8 if i connect the 0-10 analog current to the terminals specified in the vfd manual.

I've attached a copy of the two pages that i feel are of importance form the Leeson speedmaster manual.
All help appreciated.
Thanks

First off I would see if you can set up the vfd for forward on one input and reverse on the other. Having spindle start on one and fwd/rev on the other may make it more difficult to interface to mach3.
It should be possible to have din1 be fwd and din2 to be reverse. you will also have to have it set up so that when it sees either command it will run in that direction and if it sees neither command it will be off.
It is then easier to have M03 be fwd and M04 be reverse in mach3.

Since it looks the the breakout board pins are the same as p-port pins numbers thru the smooth stepper hook it up this way.
Pin 1 to din1 = fwd. pin 16 to din2 = rev. using the N.O. contacts.
Then go into ports and pins in mach3 and setup the same thing for pin numbers.
I don't have a computer with Mach3 in front of me or I could give you a more detailed explanation.

If you have the VFD set up with a minimum speed, be aware that when you give an M03 or M04 command the spindle will start turning, even without an "S" comand.

I will go way out on a limb and assume that pins 14 and 8 are for a step and direction spindle, which you are not using. You are however using pin 14 for this setup in a different fashion so you can't use pins 14,16, or 1 in the other places it shows up on the board.

In mach3 it is asking for "outputs" 1-6, not pins 1-6.
Use output 1 for forward and output 2 for reverse. Then under ports and pins in the output section you will set the pins to 1 and 16 for outut 1 and 2. Just make sure that you don't start using the same output for more than 1 funtion, unless you are very sure about what you are doing. You may also have to set active low or high to get it to be on when you want it to be and off when you want it to be.

I believe that you will be generating a pwm signal from mach3 and it will get converted to an analog 0-10v signal on the bob.
Make sure you download a copy of the Mach3 users manual and read it twice. I have gone thru it 3 times now and I am still amazed at what I missed.

Let me know if it helps or I can go more indepth when I am in front of a Mach3 computer

Mike, you seem to have given me the missing pieces that weren't explained anywhere . i was lost about the pins and outputs in that ccw and cw window. The rest I pretty much figured out, with the exception of the spindle enable pins. Art emailed me and says, I do not use the pins 14 step and 8 dir to enable the spindle, he says i use pin 15 step and 0 direction.
This was nowhere in any of the three manuals that i could have read. The c-11g manual actually says 14 step and 8 dir and that's all that's available there.
Maybe, I'm the first to use this type of breakout board with the type of vfd, but those pins would have been the deciding factor .
I' ve read all i can on setting the parmeters in the vfd, but i guess my next question would be tuning the motor in mach3. I've briefed thru it and i guess i could guess my way thru, but that's no good. I'd hate to be up and running and have a problem, becasue I thought it was right.
Thanks i really do appreciate all of your help

It took me 2 days to wire my first one to my dspmc and it took me 5 minutes to explain it to you. I think I could hook one up in 1hr, just to be safe.
It seems that on the second machine, all of the stuff goes faster.

I am glad that Art was able to set you straight on the pins.

Let us know when it is up and running.

Mike, Ironic that Art just emailed me back and said what he had told me about pin 15 step was a typo it is pin 14 step and 0 dir.
i should be running today, I'lll let you know. You've been a great help.
Thank you

Mike, I can't seem to get any voltage from my analog. I've gone back and read what i can on the c-11g board. i went into the spindle tuning and set the velocity to max, along with the acceleration, turned on the power and i still don't have any voltage output at the analog terminals. Do you have any suggestions? I've played with the pot and the band width, but i'm still missing something, because I get nothing more than a few ma's. Please help.

Section 5.5.5 of the Mach3 manual covers this nicely.

http://www.machsupport.com/docs/Mach...all_Config.pdf

The short version is go to the pulley setup under the config tab of mach3.

Set 0 for the minimum speed, whatever max speed is for you and a ratio of ten and try that. It should at least give you a starting point.
