Have you tried calling Mitsubishi? I agree that their documents are not always clear.

OK, I got a new battery, initialized the MC161 board, and finally got the machine to start up. Not without errors though. I am getting a Spindle error during startup. I can jog the axis' and I can home them. Once home though, I can't jog them. I know I have to set more settings correctly and send in the parameters, and tool change macros. Is there some document that is clear in the step-by-step proceedure. I have three different docs that, to me, are not as clear as they could be in the whole proceedure. It's been about 5 years scince I've had to do this and when I did it them, I made alot of mistakes. I eventully got everything to work, but man, it took a long time.
I just don't remember this spindle error last time.
i know this is an old machine but I was hoping that some one would remember what to do next.
Thanks,
Bill
Have you tried calling Mitsubishi? I agree that their documents are not always clear.
Yes I agree. Try calling Mitsubishi. They will help you through the alarms unless you can list them for us. If you have homed out the machine and it will not move it sounds like you do not have the soft limits set. If I remember correctly there are two sets of them, one set in the user parameter area and one set in the machine parameter area.
What is the spindle alarm?
Mitsubishi phone number (847)478-2100
Thanks for your replies guys. When I have the time , I will give Mits a call. I want to be in front of the machine when I call. Machine is in my garage, I'm at work.(not in my garage) Plus i have computer issues. The laptop computer that I am using to communicate to the machine is have startup issues. Luckely I have spare computer that has all the info in it.
Gosh, Its been so long since I've opperated this machine. I hope I remember how. I run Haas machines now. Much simpler.
Thanks again,
Bill
I have all the books with my machine. I entered in the parameters that were in the service book that someone (I assume the factory) entered. Would the parameters that I have help?
Thanks, but I do have the parameters.
I got my laptop to work, so now I'm ready to comunicate. I just have to remember the steps to go through before sending the parameters in. it's been about 5 years since I've had to do this. alot of water has gone under the bridge since then. i.e. I have changed jobs 2 times and run about 4 different cnc machines. It's tough to rmrember all the nitty gritty stuff for each manufacture.
Thanks again for your help. Would you like the electronic set of parameters I have?

That would be great. You can send them to devans@aeroinc.net.
How much was the battery anyway, Mine needs replacing and I have not gotten around to it.

How are you making out with this bkobernus? When inputting the data you need to make sure that all of you I/O parameters are set up for communication. Make sure the CNC is ready to receive the data before sending from your PC.
I GOT IT TO WORK!!!!!!!!!! I GOT IT GOING!!!! IT IS ALIVE!!!!!
Wow. Today was the day. For some reason I could remember what steps to take to bring my machine back to life. The hardest part was getting the tool change program in the machine and get it to stay there. It has to do with turning the edit lock on and off. Now I have to write down ALL of the steps before I forget what I did.
This board was very helpful in reminding me to do the first step. Initalize the boards after replacing the batteries. I had notes on it but could not remember what they meant.
Anyway, thanks to all for your help. I hope I can repay by helping someone else.
Thanks again,
Bill

I have a Meldas 520 AMR Control in my Feeler FV-800 that has program memory protection levels ABC.
Level A protects all data in the memories. All programs except those within the range of 8000~9999 can be input, output, edited or erased by turning the data protection key on the panel to the "OFF" position.
Level B protects all data in the memories within the range of 8000~9999.
If the "B" key is disabled in the user parameters menu, all programs except those within No. 9000~8999 can be input, output, edited or erased by turning the data protection key on the panel to the "OFF" position.
I can handle things so far, but:
The trouble is that I can not find info in the Meldas 520 AM Instruction Manual about disabling/enabling the "C" protection key.
Level C protects all data in the memories within the range of 9000~9999.
I have read this in a bulletin made by Mitsubishi USA:
"If the "C" key is disabled in the "base spec. parameter" in the machine parameters menu, also programs within No. 9000~9999 can be input, output, edited or erased by turning the data protection key on the panel to the "OFF" position."
Can you please write step-by-step how you do this?
This is necessary to know if the program "O9001" gets damaged and needs to be reinstalled.
OK, I actually found it! Guess it was a bit late at night last time I checked the manual. So below I describe it step-by-step.
Procedure for disabling/enabling the Edit Lock "C" in Meldas 500 series:
1. Press DIAGN IN/OUT button.
2. Press Menu key under the screen until you can see the option PLC I/F.
3. Press PLC I/F key under the screen.
4. Make settings: DEVICE (1001) DATA ( ) MODE ( M ).
5. Press green INPUT CALC button. You will see no change, but leave it at that.
6. Press TOOL PARAM button.This brings you to the MACHINE PARAMETERS menu which is now open.
7. Press BASE key under the screen.
8. Press the Next Page key (rightmost key under the screen) until you reach
screen 5/10.
9. Check Parameter #7 "edlk_c".
10. Set value 0=OFF.
11. Press green INPUT CALC button.
12. Now you can edit the "C"-key protected data.
13. Do not forget to set Parameter #7 "edlk_c" back to value 1=ON again after the editing is done.
14. Press DIAGN IN/OUT button.
15. Press Menu key under the screen until you can see the option PLC I/F.
16. Press PLC I/F key under the screen.
17. Make settings: DEVICE (1001) DATA ( ) MODE ( U )
18. Press green INPUT CALC button. You will see no change, but leave it at that. This brings you back to normal "USER PARAMETER" status.
Hey, if any of you guys have a Meldas controller on a Dyna machine with a 16 tool turret, could you send me your tool change program? I've been trying to get mine to work forever! It works in MDI mode just fine, but in memory mode it gets halfway through the tool change and then stops and gives a Z axis overtravel alarm. It's right before the spindle raises to clear the tool holder. Any ideas? Even if you don't know, I'd still like to compare tool changer programs. Thanks guys!
