1. Got acorn setup and bench tested, motors spinning (kl-5056d + stepper), nice acorn schematics available. Estop wired and working
2. Started to hookup this 'soyan svd-e' vfd that came with a half finished emco 8e lathe conversion with a 'generic vfd' schematic.
3. I hooked up x1 x2 to relays 1 and 2, and set the spindle fwd and reverse to those outputs in the wizard, however the buttons in the cnc12 for spindle fwd/reverse didn't seem to control the relays. I opened up the PLC view and clicked the relays on and off manually (they fire to life), and the VFD starts running (or rather it stops, because the vfd/motor started running when I plugged it in to start the tests. Depending on the two relay statuses, i can get the spindle to run in either direction.
4.
I moved on to the speed control, and connected ai1 and common of vfd to ACORN. Fired the machine back up ... and I 'smelled' something. I pulled the wires from acorn and tried their spindle bench test, no voltage. Separately I measured the ai1 and common from the vfd and no voltage present...Either way, here are my questions
1) If the vfd / test spindle gcode provided out of the box does not provide 0-10vdc, does that mean I smoked the acorn, or part of it? The acorn still communicates with cnc12, moves the axes, and reads the estop. Are there additional tests I can do to inspect for issues? I do see a black spot underneath where the socketed mini computer...!
2) I did some searching and found this topic... where the OP had a similar problem but I believe he made a mistake, where he provided the VFD's internal 10v signal direct to the acorn. I did not do that, and since ai1 and common dont provide power (i confirmed this by running VFD and measuring), not sure how it could have harmed the acorn. Can you think of how I could have possibly damaged the board?
3) in point 3 above, you'll note I couldn't use the GUI fwd/reverse buttons and get the relay states to change. Shouldn't i have expected that?
Other musings:
2a) If you read the post below the consensus is that the VFD below doesn't accept an external 0-10vdc signal, hence the white silicon over the terminals (mine had the same, or some evidence of it). I will be getting a new vfd, because I'm not sure if that is true or not, but my hitachi wj200 for my uccnc router worked great. Some good advice in the thread, 'if you're not sure, ask some people online before you apply power". However I was pretty 'sure'... so on we go. Not sure if I got a fluke/bad board

Thank for reading my mini novel, and appreciate any support ya'll can provide. I wouldn't consider myself a novice when it comes to this stuff, but also wouldn't consider myself extremely proficient.
