I decided to make some changes since I discovered some Brains features which are useful in the design of Brains file. I have also decided to split the file into two parts, one is the basic control and the other is the "bonus features". I think this makes it simpler for others to reuse my idea and adjust the necessary changes.
I have also made a short video which could be used as a simple guide. This video is just the first part. At the end of the video there are three pictures showing the brain file with the basic controls with three Mach3 commands: M3 S3000, M4 S9000 and M5.
For best detail, please watch in full screen mode. It is 19 minutes long, so if you just want to see the Brain file views you can jump directly to the last 40 seconds.Last edited by A_Camera; 28-08-2016 at 07:11 PM.

There is one HUGE disadvantage with using 0-10V, at least with the BoB's I have, is that if Mach3 is not fired up and the BoB is getting power then it will output 10V and random states for the digital outputs. This creates a dangerous situation since the spindle can start spinning when your hands are too near. This situation can never happen if you use Modbus.
I agree, this is another major advantage of using Modbus, and I will cover that in my next video. I am reading parameters like Output voltage, current, torque, power, temperature, real RPM, RPM stable... and there are plenty more, but to read those and have some use for them you also need to modify Mach3 screens used, otherwise you won't be able to see those. I have just started with this, so I am no expert, but used Screen4, which can be downloaded from Mach. I find it pretty buggy, crashes fairly often, so frequent backup of the changes is really important, but it is free, so why complain? In any case, to make modifications to existing screens is pretty simple.
Yes, I would also prefer a decent manual, but that is hardly going to happen now that Mach3 is dead. The Brains territory is even less documented than the rest. I managed to gather quite a bit of documentation spread around on the Internet about Mach3 macro programming, use and parameters, as well as about some other bits and pieces, but very little about Brains, so that is not really like skiing off-piste, more like skiing off-piste uphill. Yes, the best I could find was also Youtube video, but unfortunately not enough to help me, so I made my own. I don't know if I will write some kind of user documentation later on, because it takes quite a lot of time, but at least I will document my workflow which can be use by others to figure out what to do and how to solve their problems.

I can't disagree, although in my case I am using a CSMIO-IP/M which is held in e-stop mode by the safety relay until it is explicitly re-enabled. I think that it stays in standby until it starts communicating with Mach3 as well - I'll have to unplug the Ethernet cable while it is running and see what happens!
As I am currently using a Huanyang VFD and given its poor support for Modbus, I'm not going down that path. Still, if it blows up one day and I have to replace it, then I might well look for something that both supports the official Modbus standard and also has a usable manual!
Good luck with this project - I shall follow it with interest.

A-Camera, thanks a mil! I had been beating my head against a brick wall for weeks trying to get this going. Using your posts I got it all up and running sweetly
I registered on this board just to thank you!

Hi, I have a Bosch Rexroth EFC 5610 VFD with all the manuals. I couldn't see anywhere, which terminals you used on the actual VFD itself. Could tell me what terminals you used or direct me to the manual where I can find correct information on how to configure the VFD?
I have recently replaced all the motion control gear on my router table and so far so good. I have fully calibrated motion and just configured it with an xbox360 controller.
I really would like to have the ability to monitor and control my spindle settings within Mach3.
.
I am using the '2010 screenset' on Mach3 to control my machine and have used 'Screen4' in the past, to modify various screens in mach etc.
I have a USB to RS485 dongle setup and showing up as 'COM4' on my windows 7 machine. My EFC5610 is already setup and controlling a 3ph 5.5kv max. 17,400RPM Perske spindle.
I have been reading through your posts on the subject on various forums and I just wanted to ask your advise now as I'm just about to start? After all you did, what is the best way to go about setting this up from start to finish?
Would it be helpful if you sent me copies of your Mach3 brain file and the Modbus configuration file with a workflow? I was thinking that I'd have many of the same parameters as you, between Mach and the Rexroth VFD.
Any help will be much appreciated!
Regards!
Darren

Hi Darren,
My manual says:
14.3.2 Modbus Interface
The Modbus communication is via RS485 interface, see descriptions on RS485+ and RS485- in chapter 8.1 "Wiring Diagram" on page 50 and chapter 8.3.2 "Control Terminals" on page 65.
It explains how to wire in details. Anyway, I posted on CNC Zone as well as on my Youtube video. Did it help?

Yes it did help indeed! Thank you again. I can now send M3, M4, and M6 commands via the MDI in Mach.
The only thing that I have to do now is change the ' RPM DRO' To read and display the 'True RPM' Values.
I know that I have to use a screen editor to change the 'RPM' somehow from no. 39 to '1002'. Thing is, I'm using 'Screen4' and 'MachScreen' and I cannot find a procedure to do this.

I'm using the 2010 Screenset so the original Mach script editor doesn't work with the 2010 set. I have however found a way to change the DRO no. to 1002. I've used 'MachScreen' to do it, you can see where to edit it when you open the screen file, goto -> view -> overview. Here you can see an overview of all the DRO's LED's & Buttons etc. All the values can be edited here on-the-fly. So I've made the changes to the screen but I will not know if it is working until I get in to work tomorrow. I will let you know how it goes...
