Meldas-M3 Dynamyte DM4400M Problem

Hello, I am new to this site but have been interested in CNC for sometime. I was GIVEN a CNC mill but have not have had any luck getting it running. When I powered it up I could not get anything on the CRT. I have been toying with retrofitting it like the Bridgeport project (Stepper motors) that is in one of my machining magazines. Does anyone have any suggestion as to possibly getting the original machine running (possibly just reloading the paramenters?) or mayby using the existing AC servos and getting a different controller? Any thoughts would be welcome. Thanks David

Hi Sandro.
Welcome back.
Does the borrowed computer have a real COM-port?
Have you configured the computer, the DNC-program and the CNC to the same parameters?
Have you built a cable as described earlier in this thread?
Please tell us your current status with all equipment and settings used.
For just sending and receiveing complete programs to and from the CNC you should be able to use most modes such as Tape, MDI, Edit and Auto.
But when running the CNC with programs directly from the PC (drip feed), you must use "Tape" mode. Sometimes "Tape" is also called "On Line".

Hi friend, please see below.
The computer have a real COM-port and the same parameters is present in boths and also the cable was built as described.
But about the modes to sending and receiveing complete programs to and from CNC, maybe this is my error, I'm not making this correctly, maybe I'm using DNC mode to sending / receiveing programs.
Because I can make this from the PC, for exemple, a program called 100 on the CNC, on the PC I just call the same name 100 but occur a error, and the same occur when I try sending a complete program called 200 from the PC.
Are there some procedure to sending or receiveing complete programs from the PC? About the names of programs, how can I call them on the PC? Do you know if is it a manual with details or training to making comunications with CNC?
All Best.
Sandro.

Sandro,
With "mode" I meant the setting on the CNC. If you have a "DNC"-mode on the CNC that should work.
When sending programs to the CNC, I start the DNC program on the PC, open a program so that all program lines are on the PC screen. Then I press "send to CNC" in the DNC program. Then it says: "Waiting for CNC".Then I go to the CNC, press Diagn. >> Data Input>>Input and the program goes from the PC to the CNC's memory and stores the program there. Note, there must be enough free memory capacity left in the CNC or it will fail. If not, you must free some CNC memory space by erazing not used programs.
I personally will not store programs in the CNC memory anymore since I got my DNC drip feeding working so good. I will just run all programs directly from the PC to the CNC, with the CNC set in the "Tape" mode.
When receiveing programs from the CNC, I start the DNC program on the PC and press "receive from CNC". Then it says: "Waiting for CNC".Then I go to the CNC, press Diagn. >> Data Output, select a program and press Input. Now the program goes from the CNC to the PC.

Hi Friend,
I followed your tips but nothing and also I tried use the Hyperterminal and nothing too.
My settings are the same that you have posted and now I'm using the program call Ncnet Life from Cadem. Do you have others tips to give me?
All best.
Sandro

Sandro,
Please list all your parameters for CNC, PC, DNC program, like I have done below, so we can check for any possible error you may have overlooked.
I have a 1996 Feeler FV-800 with Mitsubishi Meldas 520 AM control and have no problem drip feeding at 19 200 Baud with a 20' serial cable between my PC and the front panel. Remember that there is also a 22' internal intermediate cable from the front panel to the control at the back. Total L=42' !

Hi,
Is there any Dyna Myte 4400M user who have mechanical drawings about that machine. I have 1997 Dyna Myte with mitsubishi control...and i also need information about backup battery, where i get new battery and what is the price? i see that someone is using phone battery...
I give information if there is someone who like to ask something...i transfer my programs with KwickDNC software, it^s cheap and very simple to use...working like a traintoilet...(Finnish joke)

Hi Friend,
Please take look on page 5 according address attached berlow, you will find details about your question.
http://www.factorydaily.com/forums/showth...t=14443&page=5 (Meldas-M3 Dynamyte DM4400M Problem)
All the best,
Sandro.

I need the schematic electric of the Dyna DM4400M - N SERIAL: 030 571
Model CNC
TYPE: FCAM3A
SERIAL: C3167250449
The machine is stopped and we're not getting fix it. Could anyone help me?
My email is [email protected]

Hello Dear,
Sorry but I'm in vacation and no access to manufacture plant. I'm going back just on the september end.
So, sorry.
Regards,
Sandro.

Friend,
I checked for your information and it is ok. Now I'm using the program called Andrew Carter's software for RS232 communication too.
But I can't find in my CNC the procedure to sending / receiveing programs, in special the screens "Data Input" and "Data Output", when I press Alarm/Diagn shown me a screen called on top left (PCL-I/F) and on top right ALARM/DIAGN 4.
I'm in front of the CNC with a computer linked on internet and on the CNC.
Thanks.

OK,
here is a close-up picture of my control panel.
I press DIAGN IN/OUT button (4:th button in top row). Then I press soft key under screen for INPUT or OUTPUT, depends on what I want to do.
Very important: To be able to send or receive programs or data from the CNC, you must turn the MEMORY PROTECT KEY to the OFF position. You can see the memory protect key on the right side of my black control panel.

Then you just do as I described in my earlier posts.

Peter,
About the cable you sad :
"at 19 200 Baud with a 20' serial cable between my PC and the front panel. Remember that there is also a 22' internal intermediate cable from the front panel to the control at the back. Total L=42' .
We are working with back panel and our cable has 180' maybe I will have make a adjustment on this cable, to connect on the back panel I will need a cable with 50' is it possible?
I sad before about the program that is the same from you but when I make a test serial port appear some error with RTS/CTS signal and communication at baudrate, maybe this is caused by the dimension cable, isn't it?
My control panel is different from you, I would like to sent a picture to you but now I do not have camera here.
I will be here for more 2 hours please fill free to contact me.
Tks,
Sandro.

Sandro,
I have not used so long cable yet, because I did not have to, and now I use LAN + Ethernet adapter + only 0,8m RS232 cable directly to the Mitsubishi control, which works very good at 19 200 Baud.
I believe that your 180' cable is too long, especially at 19 200 Baud. I think you could cut to minimum what you need (50') and try it at the front panel + via your intermediate cable of (22' ?) first. If no good, then try the 50' cable direct at the back panel. If still no good, then reduce Baud rate to 4 800 Baud and try again. Note you must change to 4 800 on all places!
And please send pictures of your front panel with all buttons, front RS232 connector, back panel with connectors etc...

Hi again,
Your post arrived a few seconds before mine, so I only saw your pictures now. Oh, you have a PROGRAM IN/OUT button! Then it must be this one that you should use! Just check again with existing cable and settings before you do anything else.
And I think, in your case, for only sending program to and from CNC, maybe you shall use the MEMORY mode. It may be possible that you can use all of modes MDI, MEMORY and DNC for this so try them all.
I think that the DNC mode is for drip feeding programs directly from a PC and is probably the only mode that works for drip feeding.

Peter, in attached are the pictures, one is the connector from back panel another picture is a result after a test of comunication, this result is with cable 50'.
But I need change the baud on CNC now is number 0, which number must I need work?
Tks,

Hi again,
Came to think about your back panel connector. Sometimes the back panel connector can have a different pin-out. Have you checked this? Can you try the cable in the front panel connector (do you have such?)

Peter or Viking sorry I don't know more how is...
I tried this parameters and nothing and also I checked the PLC parameters too. Do you konw the program that I am using? I tried make a test of communication and appears that errors showed on those pictures. I dont know what do here, in Brazil we don't have specialist in this subjects.
Att.
Sandro.

Yes we have a blue circular connector this is to use on external functions such as an indexer. The output signal wave-form is pulse type with a width of 300 msec. Yes we have a connector in front of painel, but the paramenters to CNC is diferent, isn't it?

Friend,
I checked for your information and it is ok. Now I'm using the program called Andrew Carter's software for RS232 communication too.
Thanks.

Sandro,
Does this program work with Hardware Handshake = RTS/CTS mode? If not, that may be your problem!
I tried another program earlier and it did not accept this, so I had to run it in XON mode. That meant that I had to change some of the parameters in the CNC and also in the PC and the DNC program.

I don't no, I really don't no!!!

Yes we have a connector in front of painel, but the paramenters to CNC is diferent, isn't it?

No, I think that this front RS232 panel connector is the "Channel 1" connector and the first choise to use. If it says "RS232" and is a 25-pin D-sub female socket, try it.
And open the DNC program and check the settings for "Handshake", or "Protokol" etc. There should be the RTS/CTS choice. If not, tell me what choises you have. Take a screen shot or photo of the screen and post the configuration menu so we can see it too.

Sorry my last replay, I would like to know that I do not know but I would like to know.
Well. I will go to home now here is 7:40 PM and I'm tired.
Until the moment thanks a lot of, maybe tomorrow morning I will seat in front of CNC to thing in same solution, that God help me...
Bye,
Sandro.

Please see photos in attached.

Hi Sandro,
This looks OK to me, it was possible to set RTS/CTS.
Now I am curious to see what happens when you use the front panel RS232 port.

Hi friend,
To connect in front painel, the parameters to CNC is the same posted later?
I have somes questions?
Is there other think that I could test or check on CNC or PLC Mitsubishi M3 Meldas ? Is there some tests that I could make to check the port RS232 without a computer?

Sandro,
I don't know much about troubleshooting RS232 on CNC. Have you re-checked your cable so that all pins are right, also the jumperings?
Did you check if there is an intermediate cable from panel to control that is loose or something. Probably not likely that it is loose or that both front and back panels have same error. But worth a check just to be sure.
/Peter

Peter,
I will check it in front and back painel, my cable is correct. Could be a problem to me the Windows XP to work with RS232 with CNC of the 1990?
Sandro

No it should not be a problem with XP. I also have XP and it works good.
The parameters should be correct especially if using front panel RS232, which is the "normal" CH1 port. This port is connected with an intermediate cable, SA21-1, to the 15-pin Dsub female "CSA-21" port on the CNC control in the Electrics cabinet. Note, this is how it is with my Meldas 520 AMR. Maybe it is a little different with Meldas M3!
About the RS232 cable that you are using:
Are you using "My cable" as shown in post #48 or "Your cable" as shown in the Word-file in post #42?
My cable:
PC side 9-pin Dsub female <---> CNC side 25 pin Dsub male
2 RxD <---> 2 TxD
3 TxD <---> 3 RxD
5 Signal Ground <---> 7 Signal Ground
7 RTS <---> 5 CTS
8 CTS <---> 4 RTS
Pins 4 DTR & 6 DSR are jumpered at PC side's 9-pin Dsub female
Pins 6 DSR & 20 DTR are jumpered at CNC side's 25-pin Dsub male.
Your cable:
PC side 9-pin Dsub female <---> CNC side 25 pin Dsub male
2 RxD <---> 2 TxD
3 TxD <---> 3 RxD
5 Signal Ground <---> 7 Signal Ground
7 RTS <---> 5 CTS
8 CTS <---> 4 RTS
Pins 4 DTR & 6 DSR are jumpered at PC side's 9-pin Dsub female
Pins 6 DSR &
5 CTS
are jumpered at CNC side's 25-pin Dsub male.

I don't think this is correct.

Pins 8 DCD & 20 DTR are jumpered at CNC side's 25-pin Dsub male.
If you use "Your cable",
change the jumperings
at CNC side's 25-pin Dsub male to this and try again:


Remove jumpering
from pins
6 DSR & 5 CTS
at CNC side's 25-pin Dsub male.


Remove jumpering
from pins
20 DTR & 8 DCD
at CNC side's 25-pin Dsub male.

Pins
6 DSR & 20 DTR
are jumpered at CNC side's 25-pin Dsub male.

After these changes, "your cable" will be like "my cable".
Use Front panel RS232
/Peter

Hi Peter,
Uah!!! That explanation, very cool.
Today I was out office, but I will check this configuration from the cable and as soon as I have some news I will post here.
Thanks again,

Hi Peter,
I can't managed yet... I need recheck for the all information.

Hello, hello, hello,
I have good news. I can sending and receiveing programs now, that's cool dude...
I will need your help to work with DNC mode. But I'm very happy.
Thanks a lot of friend.
All Best.
Sandro.

Hi Sandro,
Congratulations!
What did you do? Was it the cable? If yes, then perhaps you can step up again to higher baudrate parameters?
Do you use the front panel port?
If this works, I can also show you how to communicate PC - to - CNC and drip-feed via LAN (Ethernet network). No problem with even 100 m cable etc...
And now you must try to drip feed.
But before you try, take all tools out of the ATC and spindle, remove any vises and fixtures from the table and make sure it only can cut AIR.
Then just open a program in the DNC-program in PC, press "Send to CNC". You will se message: "Waiting for CNC". Go to CNC, turn to "DNC" mode and press "Cycle Start" button. The machine shall now start running the program.
Do not store your programs in the CNC! Store them in the PC and make regular backups. When you can drip-feed from the PC, there is no need to have programs in the CNC, except the tool change macro etc.
You must post and tell exactly what you have done, mistakes, fixes etc, so we all can learn from this.
We all want to know.
/Peter

Peter,
On next Monday I will be on office then I can describe to you all steps, you know, I can't belive yet, that's challenge !!!
Firstly, on the Monday morning I will try running with DNC mode because this is very important to us, our programs are large.
Have a nice weekend to you.
All best,
Sandro.

Sandro,
This is strange.
1. Is there no "Send to CNC" button in the DNC program?
2. Why do you have to go through all those steps to start a program at the CNC? Can't you just press the "Cycle Start" button on the CNC?
3. I think with any normal DNC program you can send the selected program over and over again just by pressing "Send to CNC" another time. As a safety measure, you should always press "Reset" on the CNC, just to be sure that the buffer memory is really empty before running a new session.
Have you checked these things with AMC Software's support?

Peter, see the screens that are used to transfer programs from PC to CNC.
CNC Transfer 1.doc
CNC Transfer 2.doc
CNC Transfer 3.doc
CNC Transfer 4.doc
CNC Transfer 5.doc
Sandro.

Sandro,
Thanks for the pictures.
I can see that there is a "Send" button, but then there is an extra "Start" after that. So far I am not impressed by this DNC program.
When drip-feeding a program, can you actually see the data flowing both in the DNC and the CNC?
What about the CNC: Can you really not start it by simply pressing "Cycle Start" button?
In "TAPE" mode (your "DNC" mode) with my Meldas 520 AMR I never have to tell the CNC which program to run etc..., before I press "Cycle Start". When I press "Send", the data from my DNC goes all the way into the CNC's buffer, just waiting for me to press "Cycle Start".
If you can not run the program from the DNC again without restarting DNC and/or CNC, get a better DNC program. A program that is opened in the DNC should remain there for re-use, editing etc. until YOU decide when to close it.

Peter,
Yes, I can see the data flowing both in the DNC and CNC.
Right, I can not restart it by simply pressing "Cycle Start" button, when I try appear a message "Program is running".
I am not sure about your procedure in my CNC, but in mode DNC is need call the program and select number 1 on gap call TAPE after that I press "Cycle Start"
I do not know other program free, this program was indicated on thread posted here (http://homepage.ntlworld.com/amcarte...p/download.htm), then I tried use anothe program called Cadem program (http://www.cadem.com/dnc/freednc.htm) this is free but to mode DNC is terrible, just to transfers programs is good. Could you indicate one good free program?
All Best,
Sandro.

Sandro,
I'm using the same DNC software and Dyna machine. I can transfer files to the CNC at 19200 baud but cannot DNC at 19200. DNC runs at 9600 baud maximum. DNC at 19200 eventually gives a communication error.
To run DNC:
- Open the file on the PC and press the SEND button. That will give you the screen telling you to get the CNC ready to receive. This enables the COM port on the PC so the Dyna does not give the DEVICE NOT READY alarm when you search for the program number.
- Go to the CNC and set the MODE SELECT switch to TAPE/DNC.
- Search for the program number and be sure to enter 1 in the field for TAPE ().
- Go back to the PC, and press the START button in the DNC program.
- At the CNC, the first line of the program should be loaded and you can press CYCLE START to begin the program.
The older Mitsubishi M3 control is not as advanced as the M520 Peter has and will not DNC at 19200.

David,
Do you get any red lights on the control boards? Not the operator console, but the computer inside the electrical cabinet.
If so, then the most likely culprit is a dead battery. There's two screws on the front of the computer that you need to take off to get at the battery, I think it's at the bottom of the power supply.
Before replacing the battery, try re-initializing the control. This should work if you've had the power on for a while and nothing else is wrong with the control. You should see a DIP switch on the front of the computer with 8 switches on it. With the CNC off, turn on switches 1, 3 and 8. Turn the CNC on and wait for the green led's on the CPU board to light up, takes just a few seconds. Turn the CNC off and turn the DIP switches back off. Turn the CNC on and watch the led's on the CPU board. If you get all green light's, then you are in good shape.
If you get this far, you may also need to check your machine parameters. I would look for any documentation that might show what the parameters should be set to.
Regards,
Scott

I've got two of these machines and Scott is probably right. The battery went dead and the MC161 card needs to be re-initialized. Contact Mitsubishi at 714.220.4796 and speak with them regarding the problem. They will walk you through the procedure or fax it to you.
After initializing the main card, you'll also have to reload the canned cycles, enter the tool change macro and possibly the machine parameters. If you need the tool change macro or machine parameters, I can email you them to you.
I highly doubt you'll get a retrofit that will outperform the control on that machine. It will rigid tap at 2000rpm, rapid traverse at 500ipm, 5hp 10,000rpm spindle, and coutour at 200ipm.

Scott, Yes I do get lights on the board marked MC1619-1. There are two horizontal lights (both red) then below the right light there are two vertical lights ( both green) and finally there are two more horizontal lights ( both red) All these lights are located around a small toggle switch. The battery was dead as I only had .1 VDC on it. By the time I had to shut down, I had 1.86 VDC. I tried the procedure that you wrote of but the lights did not change to all green. I shut off the machine at the source but I can shut it off at another small toggle switch located on a board marked PD19A. Is the procedure you wrote of the same procedure that CAPRIRS is referring to from Mitsubishi for re-initializing the MC161 Card? I do have a sheet with all the parameters on it but am kind of at a stand still. Any additional thoughts as to what I can do? Thanks Again David

David,
The initialization procedure is the same, but there's more to it than what I described. The complete procedure, like Caprirs said, also involves reformatting the program memory and reloading the canned cycles and parameters. I gave you the short version because until you get the screen back up, the rest is pointless.
The battery should be 3.6VDC, so it's possible that there just isn't enough voltage to get the control to come back up. I'll look tomorrow and see if I have the initialization procedure somewhere. If I can find it, I'll post it here. It sounds to me like you need to replace the battery before going any further.
As you noticed, the switch on the power supply (PD19A) does the same thing as the control on/off switches on the operator console. I think the toggle switch on the MC161 card is a reset switch.
Regards,
Scott

My recollection was:
- DIP switches 1,3 & 5 got switched on
- then power on the control for 30 seconds
- shut down
- flip the switches back to off
- power back up again
Once you can get a screen at the front, there's a sequence to go through to format the memory, reload the canned cycles, initalize the ATC, re-load the tool change marco.
I certainly have a feeble memory on that so that's why I recommended calling the guys at Mitsubishi. I used to work for Dyna about 7 years ago but I can't remember some of the procedures. The number I listed above is to the office in SoCal.
Get the machine working and it's worth $12K-$15K.

OK, So far so good. 1,3,5 dip switches procedure worked and I have a screen. I jogged all three axis and everything moved just fine. I called Mr Mitsubishi and he told me to load and save a small program to see if the memory needs to be reformated. Does anyone have a shortened program entry procedure? By the way, Thanks for all the help, I have been messing with this thing for about a year on and off getting more and more frustrated all the way. Mr Mitsubishi said that I was about 90% there.

You can enter a program by:
- pressing the Program/IN-OUT button at the top of the keypad
- press EDIT softkey at the bottom of the screen
- press PROGRAM softkey
- enter a program number (1-7999) and then press the green INPUT key
- type in text for a program like G0 G40 G90. End each line of code with the EOB (end of block) button on the keypad. The control does not complete the entry until the INPUT key is pressed.
Now you should be able to shut down and re-start to see if the program was retained. Upon power up, go back to PROGRAM/IN-OUT and press the softkey at the bottom of the screen marked FILE. Your new program should be there. If not, you have more procedures to go through to format the memory and reload the canned cycles.

Thanks for all the help. I got it to accept programs and entered in the tool change sub. and that is working fine. I am now working on the DNC.
Thanks Again.

Can anyone help with cable pinouts and port configurations for DNC on a Mitsubishi Meldas M3 control ? Any thoughts would be welcome.
Thanks
