Installing the Acorn with Adtech CNC drives

Post by dmbgo »

I have received my new Acorn.
Initially I bench tested it and the Acorn was allocated an IP address by my router and I have installed and licensed the CNC12 Lathe software. The PC is Windows 10 and I followed the W10 setup video, it meets the requirements listed. The CNC12 software has no issues communicating with the Acorn board.
I went ahead and started to configure the Acorn board, to the ports labelled STP1 etc for X and STP2 etc for Z. by installing the same step and direction outputs that I used on my Ethernet Smooth Stepper board.
I connected the 24v output from the power supply to my 12v in line to the servo controllers (they are rated 12 > 24v for inputs).
The servos are Adtech AC servo drivers (QS6) with ACH06040 motors.
I am now at the point where I think I need to take one motor and controller off the lathe and get it working on the bench. I'm guessing that I will need to input some parameters, like the number of steps per revolution etc.
How do I do this? I have found the wizard in the CNC12 software and created a custom servo type, but I haven't worked out how to input any parameters, or how the parameters translate to the information in my manual. For example my guess is that steps per rotation are the same as encoder lines per revolution, but that's only a guess and I don't know how to input it anyway.
Is there some sort of setup manual for servo types that aren't listed as a default for the Acorn?
Thanks and sorry to be a pain, I have manuals for the Adtech AC QS6 servo drivers and ACH06040 motor, but I'm not sure how to attach them to this post, here is a synopsis of the servo motor parameters:

First Welcome.
Second, you would do well to follow this post to provide more information about your build:
viewtopic.php?f=60&t=1043
Do you have a link to the manual for the drives? Please post it here.
What you did post suggests that the encoder is 2500 pulses per revolution. So in the wizard under axis configuration, try and enter 10000 steps per motor rev. Without documentation for the drive, we can't offer much suggestion just yet.

The motor specifications can be found in more detail within this document, the data you want is for the ACH6040 motor:

The QS6 AC Servo drive manual is here:

So rereading your post, the lines per rev value of the encoder on a servo motor are equivalent to the pulses per rev setiing in the Acorn Software?

Is there some step by step documentation that explains how to set the Acorn up?
I have found the bench test videos, but there doesn't seem to be one on customising Acorn to suit particular servo drives that aren't in the list of standard drives.
For example (ignoring machine safety for the time being), How to enable the board, tell it to use specific signal outputs as particular axis drives etc?

Yes, generally X4. In your case 2500x4=10000
Set your turns per rev to 1 for the bench test.
If you do an MDI of G01 XYorZ1.0 F10, the motor should turn one revolution.

I'll look at your manual later.

There is no Acorn Installation Manual yet. It is being worked on.
Because your drive is not listed does not mean anything. Acorn is a step and direction motion controller.
There are two ways to get the step direction signals for drives. The DB25 which is meant for +5V logic drives.
You will use the headers on Acorn.
Your manual shows SEVERAL models of drives WHICH model specifically do you have. Then you can look at the example wiring diagram in the manual.

Because you are using AC servo drives, I suggest you follow the Acorn System Schematic. It is in the schematic package, but I have attached it here for convenience. Do your basic bench test first. Get CNC12 4.50 loaded on a Windows 10 CNC PC meeting the minimum system performance requirements:
Be sure to use a 1080P Wide screen monitor. There is a new bench test video on Centroid's YouTube Channel. Get all that done first.

THEN connect one drive and one motor to Acorn and get it turning.

Is this your first CNC Control retrofit?

Thanks for the reply Marty, no it is not my first retrofit. I built a CNC router, back in 2002, this got me interested, I then converted my CQ6230 Lathe to stepper motor based CNC using Mach3 in 2006. Subsequently I bought a King Rich KR-V3000 mill and some GSK AC Servos, using a proprietry GSK MD980A controller, which I have used as a manual mill with powered feeds. I have also built another CNC router of my own design that I use for PCBs and engraving.

I have the Adtech QS6-AA015M servo drives on the lathe.

OK, you have previous experience so you should be able to muddle through.
You say the Adtech drives are "on the lathe" does that mean they are currently running under something like Mach?

All you need to know really is that
-Pul
-Dir
-Ena
get connected to the Acorn header
You need to provide voltage (12-24VDC? If 24VDC you can use the 24VDC from the Acorn power supply)
TO the drives:
+Pul
+Dir
+Ena terminals

ALM- to COM
ALM+ to Acorn input

In the Wizard, go to the DB25 and make sure it is set to HEADER not DB25

You will need to configure the drive to be DISABLED on power up and require the ENA signal to operate. Acorn will ground (Enable) it when you try and jog the axis, home or go into MDI.

You really should have at least one motor and one drive on the bench for testing. Once you have things sorted and running, then build/wire your cabinet.

Suggest you use a shielded cable from Acorn Header terminals to your drive. Ground the shield drain wire on the Acorn side.

These are just suggestions. Read up on your drive manual. You may need to set some parameters in that drive too.
