Welcome to LinuxCNC.org

Its probably best to verify the enable circuit with a mechnical switch first
Most drive enables just require a switch closure to activate
The 7I77 enable output is just a switch (though a polarized switch),
on for enabled and off for disabled.

It seems to me (from reading all your posts) that you are kinda in a hurry and are jumping around with different techniques for getting this going.
First my recommendation is for now to pick one way to make the configuration either pncconf or Petere's prebuilt sample.
Either one is fine just pick one. then as the errors or troubles come up announce them to us and we will try to help.

When describing an error or problem please try to give as much pertinent info as possible.
For instance tell of a following error is not much help. I now assume the motor didn't even try (important information!)
Telling that the openloop test didn't work and why would be helpful.

It is specifically for testing the output of servo drives and input of encoders.
For a servo with feedback (the encoder) it's important to check that the output and the feedback agree on direction of the axis.

If you have a multimeter use the openloop test to check the output of the analog pins without a drive connected.
does the pin output at all? Is the scaling right?
turn the encoder by hand - does it register properly? is it scaled properly? does the numbers change even when the encoder isn't moved?
after that then you could connect the drive and then check the directions match properly.

If the openloop test doesn't work (assuming i haven't made any errors in pncconf) then its not going to work anywhere else either!

and don't forget that even after all that - you must tune the PID loop a mistuned PID loop will give you a following error!
When it goes time to tune the PID - It's suggested that one open up the following error limits - pncconf sets them fairly tight.

Oh and read the manual if you haven't - most of what i have just said is in the manual - look under the PNCConf section if you continue to want to use PNCconf. PNCconf also has help screens (only in English) that basically explains the pages.

Hope that helps.

Thanks for information from both of you.

cmorley ! I will try again with pncconf. But this time I will be prepared. My machine will run as openloop till I get something out of it. Also I will take care of your notes.

Hopefully I didn't put you off from asking questions - We are here to help - we want you to succeed almost as much as you do !
PNConf is not well tested with the 5i25/7i77 as of yet so if an error shows up please speak up and I will try to fix ASAP.
Some of the help pages are missing a few details about specific 7i77 needs.
eg scaling of the analog output
I'm going to update it soon.

I always appreciate and try to take care of precaution notes. This was my stupidity to did things in hurry. Even I didn't try to check with multimeter. Or try to put a switch between circuit as drive supplier also suggested me. hopefully I will do better next time.

I am really thankful to all the kind people helping me here.

I'm back again with a couple more questions -

I've set up my spindle control and it seems to run correctly from AXIS after a little massaging of the scaling numbers (it appears that the analog input of my VFD wants a max voltage of 1.5 to get 60 Hz which for some reason works with a scale of about 6.4 - however I'm not sure what AXIS' default spindle speed is supposed to be when you leave spindle at 100% and press the CW rotation button). When I tell it to run in reverse, it correctly sets the spindle CCW pin but the PWM pin output stays at 0. I've seen this discussed here www.linuxcnc.org/index.php/english/compo...57&catid=38&start=18 with a workaround but I see at the end of the thread that you updated PNCConf (or was it stepConf?) to fix it. I wanted to see whether I should proceed with the workaround or if there's a cleaner way of fixing this behavior.

I'm also having trouble getting my servomotors to run in AXIS. I'm able to run them in the open loop test dialog in PNCConf but whenever I try to jog them in AXIS I get no motion whatsoever and a following error. The ".. Amplifier Enable" pins, which I have connected to X/Y/Z-release relays on my end, are not being activated when I try to jog in AXIS like they are in the open loop test. Now the complication is that there must be some intricacy of my Bridgeport control circuitry/servo amplifiers because if I jumper a logic high signal to a release relay, I hear a progressively louder buzzing noise for about 2 seconds until the main contactor trips out completely. This is pretty bizarre. I can't find any differences between what is on and off when I successfully run the open loop test and when I try to jog in AXIS except the release relay drive signal being low. I would appreciate suggestions on this issue but the question I imagine is more answerable is "Why aren't the X Amplifier Enable.. etc pins being activated when I jog in AXIS?"

I also would like to figure out how to get my multi-axis MPG encoder to work. I don't think it does at the moment despite being set up in PNCConf; I don't see any activity when I rotate it but maybe I need to press a button in AXIS to get it to run. Getting the linear axes running is the more important issue at this point though.

Any pointers are appreciated.
