Hitachi seiki VK-55 retrofit advice?
« on: May 05, 2008, 12:36:23 PM »
Hello,
I just purchased a basket case VMC.
It needs alot of work and I am looking at 10K just to get the controls going agian.
This would be the 1997 seicos control, and who knows when it will be smoked again.
Would it be a good idea to try and retrofit something like this with mach 3?
The only thing I can see causing a problem would be controling the spindle drive, it looks like the OEM control uses a digital bus for all the drives.

Here is a link to it on ebay:

Let me know thanks.

Hmmmmmmmm, lots of questions to ask. You need to find out what type control signal the drives will take. Are they not analog? I doubt they are step and direction.

Jus figured out that it uses yaskawa drives, that is a good thing because I think it might use -+ 0-10 V
I should be able to make Mach3 control that.
Let me know what you guys think

Thanks
