I recently purchased a MC-50VA mill with a OSP5020M controller that has not run in several years. On power up we had several drives that had faults that needed to be removed and serviced. Also...
Algirdas,
Looking closer at the components that you suggested. The SF3B41 is a thyristor. The C84 is a diode and it checked continuity in one direction and open in the other so I am going to...
Algirdas,
Here are a couple of close up pictures of the area that you circled. I know that my eyes are getting bad but I just don't see a fuse in that area. I hope you can shed some light on it...
Thanks for the input. Unfortunately I don't have another spindle drive to switch out with my current drive so it looks like I am going to have to get it powered up so it can communicate before I can...
Well, let me try this again. I thought that I had added the pictures to my posts.
Thanks,
David

aike, thanks for the schematics and files. I will try and get the schematics translated but I have a pretty good idea of how you went about your retrofit. If anymore of you have some schematics...
I have acquired an old Hypertherm Max100 plasma torch. I basically got it for free because they were not sure that the unit worked. When I powered it up everything seemed fine and when I tried to...

Thanks for the input. I will go to your website and look at your cards. I am sure that I will have plenty of questions for you as I get further into this project. By the way, I have...
I have a Hurco KM-3 mill with Ultimax 3 controller, Servomate SM1090-1110C servo driver and Electro Craft Corp servo motors. The Ultimax controller is no longer functional but I believe my servo...
Hi,
I am working on a Hurco KM3, trying to bring it back to life after several years in storage. The control boots up and I can move all three axis but I can only move the cursor in the horizontal...
You are correct that the opto pulses when it sees a clear spot on the disk. What I saw on the scope with the computer mouse is a pulse even when the mouse was not moving. I wasn't very clear on my...
