I was afraid because in the Mazak VMC from the wiki the author decided to replace the drives. What I have to do know is to look for some information about the resolvers and I think I could try it out in the near future (January most likely). My idea is to make the first test without touching anything on the original CNC. I think I'm going to put the PC next to the machine and move the servos and try to tune them. The other thing I need to control is the turret DC motor, now it's working with hall sensors only, I guess some hal logic will work just fine. -- *Leonardo Marsaglia*. -- Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!

I'm going to check out now the forum to know a little more about how you did it. So the drivers work with +/- 10 volts, that's great because I couldn't find anything about that yet, but anyway I could measure the input of the drivers since the machine is working. -- *Leonardo Marsaglia*. -- Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!

Indeed, once you find where the analogue voltage has to go and which wire is which on the resolvers it should all be relatively simple. With apologies to jon@pico-systems (who has a system that would work well) I think this sounds like a perfect fit for the Mesa 5i24 and 7i49 combination.

I was trying to find your posts on the forum but there are so many that I can't. Can you point me to the post if you remember the name of it? or may be your user name on the forum?. The control of the machine is a Mazatrol T1. The servo motors are Mitsubishi, and the drives are Meldas. The servo drives model numbers are TRA-31A and TRA-41A. The main concern for me is how to set up the connection to run the drives with LinuxCNC. From what I could read, it seems that if I let everything as it is, and run the drives with the ready signals and the analog voltage for the velocity they should turn. The tachos will be telling to the drives the actual speed and I would only have to close the loop on LinuxCNC using the resolvers. I guess it's not more difficult than that.

hi looks the same servos as on the M0 which is a machine i retrofitted, its a Mill but the same deal check the linuxcnc forum i put alot of info on the drives on there when we did our retrofit with the old DC servo drives... if you need to know anything else let me know ill try and help the best i can... what is the melda control model? or more so what are the servo drive numbers i might have a manual of sorts rob -- Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!

It seems the driver uses tacho generation to close the speed loop within itself, and the only signals I need to replace are the analog voltage for the velocity command and some of the ready and fault signals to make it work. Also the pin information is a great help to start testing. I'm not sure about one thing in the pictures of my drivers and it's the fact that there's a connection between the two of them, I'm going to see if I can find out something on my PDFs but I'm not sure about what that might be for. I'm planning on use the resolvers as you suggested since they work really great and also everything is already mounted so practically I don't have to touch anything of the mechanical units. I hope I can do some testing soon because replacing the original control will give me a lot of new functionalities.

There's an interesting section there about how to tune the parameters using the presets on the driver. I think I saw something like that in one of the PDFs that I have, I don't know if it's the same.

[Emc-users] Running Mitsubishi Meldas DC servo motors with LinuxCNC
Hello to all! A few months ago our Mazak spindle died and we replaced it with a new one of the brand Yaskawa. The lathe is behaving well but it's a good idea to replace the control with a LCNC machine following a planned schedule just to avoid the emergency of replacing it in case of a sudden failure on the Mazak original cpu. I've seen that there's a link on the wiki with a VMC Mazak retrofitted to LinuxCNC. (http://webpages.charter.net/bengvall/emc/emcconversion.html). >From what I can read on that link and what I found about the DC servos on our Mazak, both work the same way comparing the phase to eliminate the following error. I've got some info on the manuals that came with my lathe that says the following: X Axis Servo MotorZ Axis Servo Motor HD81-125 HD101-12 0.8 Kw - 1.5 Kva1.1 Kw - 2.2 Kva Here are two links to pictures of the drivers to see if there's a possibility to use them with LinuxCNC or if it's better to replace the drivers for simpler ones. http://imageshack.com/a/img537/5573/lgfKjB.jpg http://imageshack.com/a/img743/4134/rk1IuG.jpg What I find a little strange is the power of the motors, I thought that for the size of this lathe 0.8 and 1.1 kw it's not that much, but may be that's because I'm not used to work with servos, I only worked with steppers so far.
