I'm asking this because I currently do not have physical access to the controller, otherwise I'd just take the back panel off and look...

I'm looking at page 83 (transformer) in document 3HAC024480-004

It's my understanding that there is an internal transformer that can be changed based on the available input voltage. Is this correct?

Shared photo of cabinet label

The label on the cabinet says:

Type: IRC5 M2004
Voltage: 3*600V

Version: 144A 400-480V

It's a single cabinet.

Ideally because of some other equipment I have, I'd just like to run it off of the 480V.

Thanks

Greg.

OK I better understand, thanks for the example!

To make it automatic all I have to do is to attach a gear and motor with a drive and a PLC ( https://velocio.net/ace/ ) connected to the robot controller via digital IO. Four signals from the controller gives me 16 positions. The robot moves away, the PLC does the turning and gives a signal back when it's done.

This is interesting! I'm curious, what happens at the edges where you split the model? When you split the model do you overlap slightly? So there is no obvious transition in the machined surface? If I understand correctly, instead of using one model in the CAM, I'd slice up the model into N number of sections, run each of those through the CAM, then run them as N distinct jobs on the robot? Is splitting the model even necessary or can the CAM handle that?

This solution seems like it could work well for me. Thanks for sharing.

NC operator for eight years and did all the programming there for 3, 4 and 5 axis machines. Profile milling, polishing, 5-axis sawing and some lathe saw / milling of sculptures.

Odd that we both posted here! What I've done isn't too complex, I'm sure you could have done it to, especially with your background. Once I started looking at 5 axis machines for milling stone they all had the same problem, not that large of a working area. And the ones that had any size were super expensive. That's why I started to look at robots. They seem a perfect fit for large stone work.

Again thanks for sharing this solution. I going to try to find more information on indexing...

Thanks for the reply.

Coordinated axis are cool, but mostly not needed in most applications.

Is this really true for what you want to do? It sounds like you want to mill with the robot?

With your solution will you only be able to index the part (perform machining on one surface, stop machining, rotate part, start machining on next surface)? Or will you be able to do coordinated moves for milling a 3D shape? That's where I'm confused. Without the robot controller knowing of the turntable axis, I don't see how coordinated movement can work.

If you are bored, here's how I used a slew bearing for my setup:

Plain 24VDC brushed motor, very old Advanced Motion Controls B12A6D Brushless PWM Servo Amplifiers ($50USD) and a 48VDC power supply. The CNC controller uses +/-10v to the drive.

Thanks Skooter for confirming this. That alone rules out integrating another axis and the other factors are decisive as well - the costs are just overwhelming.

What were you quoted for enabling the axis in the software?
I'm looking at buying a used IRB 7600 with the IRC5 M2004 controller and would like to use a rotary axis. Like you I already have an existing rotary table that I use with another CNC machine (custom made for turning 20ton blocks of stone).
Thanks
