Well Im here to make an update.
I need some help with the last bit of wiring to my vfd.
First I'd like to show some of the things I did to get this finished. Mostly to make sure this thread gets finished off and shows how I went about getting this done for any future internet searchers with the same lathe and would like to switch to acorn as well.
I think for someone who doesnt know what they are doing here and has never done anything like this, I did a decent job...(my opinion).
So I re-wired the front control panel. After a lot of thought, all that was really needed was a estop switch, machine power on switch and a "cnc mode" and "manual mode" switch. There was a lot of room left on the control panel becuase I got rid of all the other switches so I also put in a Voltage Amperage Power Energy Meter. This one to be exact incase anyone wants one.
https://www.amazon.com/gp/product/B014W ... UTF8&psc=1 also used green led lights to show power on or "mode".
Inorder to keep manual operations for my machine, I added a second vfd and a manual control panel. When the machine is in manual mode, one vfd is getting power, the second is not. I also added a second AC contractor for this. Same vfd that came with the machine off ebay for about $80 and same ac contactor also off ebay for around $15.
The manual control panel has a 1k potentiometer, a 12v tach, estop button, start button, stop button and a forward and revers switch.
When the "mode" switch is in the manual position it turns all power off to the vfd, gecko g540, 48v power supply and all acorn components.
When the "mode" switch is in cnc mode, it shuts off power to all the manual control components and turns on all the cnc components...simple enough I suppose.
To add a second vfd and the acorn, I had to add some electronics boxes to hold them as there was no room for them in the lathe. I used shielded cable, sjoow for power and cable glands. Its not pretty, but I think it should function just fine.
To make things a little easier I also made the cover panel on the lathe act like a door by adding a piano hinge. Just drilled and tapped the holes.
For the omron spindle encoder I did a "jack-shaft" like setup. It has ball bearings and the "axle" with lock collars and then the encoder screws on to one side with the mounting holes on the encoder. I 3dprinted the jackshaft stand had planned on replacing it with one machined from aluminum, but its very strong, I'll pry stay with it for now.
My manual control has a tachometer so I know spindle speed. So I also had to add a tachometer sensor.
I have all the manual portion of the machine wired. I havent tested it or programed the vfd yet. I am going to wait for all of it to be done.
I have most all the cnc side of the lathe finished as well. All I have left is to wire the home switches and wires from the relay board and acorn board to the vfd.
I think that pretty much sums up where I am at. Just wanted to add all that so it didnt look like this thread just ended abruptly. And if any future searchers find this and need any other info, they can PM me.

Anyway I am kinda not sure how to wire this last bit up.
From the relay board there is a vfd common going to the vfd. I am pretty sure this goes to com on the vfd???
From the realy board there is a spin forward going to the vfd. I am going to put this on DI1.
From the relay board there is a spin reverse going to the vfd. I am going to put this on DI2.
From the real board there is a vfd rest going to the vfd. I think this should go to DI3. (function code p4-02 #9 pg #69 in manual)?????
From the acorn board there is AN GND going to the vfd. This is going to GND on the vfd.
From the acorn board there is AN OUT going to the vfd. This is going to AI1 on the vfd.
From the acorn board there is a spindle ok going to the vfd. It seems this needs to go to an output on the vfd??? Possibly DO1(function code p5-04 #15 pg #74)???? I have no idea.
From the acorn board there is COM going to the vfd. Does this also get put on the COM on the vfd?? Im not sure. Does this also need to be an output from the vfd?
Is this correct and can anyone help with the wires I am unsure about?? I attached the vfd manual.
All the wiring should be done after this. All I would need to do is program the vfd settings and run through the acorn wizard.
