It finished in a state without of errors - DISPLAY STATUS : 6 ; green +5V & PR leds ON , but all data had been lost . [Sinumerik 840D ; NCU 572.2 ] Could you please ,describe, how to upload the backup to make the machine workable? We found CD with files : Archive // NCxxxx.ARC // PCxxxx.ARC Ghost // xxxx.gho S7 Projekt // Apilog , CONN,..... other couple of files . I only have some experience with uploading backup to Sinumerik 810 with PCIN software and I do not have any idea how to do it .

Do you have pcu20 / pcu50 in your machine??? if it is pcu50 you can load the backup from the screen it self... check you have it??? if it is PCU20....you can load the backup through the PCIN software with RS232 CABLE Please check and revert back Regards, Prakash

I have found Sinumerik 840D , BS 002 MMC 103 , 200MHz, 64MB DRAM 256KB Cache , WIN 95 6FC 5210 0DA21 2AA1 behind the LCD screen. Let me know if I have to search again. Take care , Vlado

Ekalavya Posts: 2964 Rating: (476)	Hello, In your case your machine is equipped with MMC103. no need to check whether it is PCU50/PCU20 You can check whether your machine backups are there in the Harddisk it self. Press menu select button > go to startup > set the password after setting the password come out of the screen and the press ^ (Recall Key) goto startup press (>) etc key in the vertical key you will fing Read Startup Archive you will find your machine backups if you have kept here. select the particular backup if you have kept it and then load the NC and PLC Your machine should work.

(siemens , sunrise, evening .. ) I wonder if there is any backup stored there , is it a common to create the backup ? Unless I find it , what should I do ? However , I will report what is new tommorow , after I get close to the machine and try what you recommended . If there is the backup stored there , I would like to know if I'm able to find where is a propriet archive and what to reload and where. According to my experience it is not going to be so easy as you have described. I hope I'm wrong and your description will be enough. Take care , Vlado

It is almost impossible to do it so , if anyone does such kind of a job once a long time ... It requires step by step instructions , with some pictures if possible for the best result. I finally did it by a help of pdf that I have found . Despite it, I still have some problem - error in one axis which does not allow to do referencing and to use the machine at all. It could by some hardware problem, but I think it also could be some problem with a configuration of the mentioned axis. error of both encoders As I said the other day , I have CD with NC and PLC files and I have a feeling that these files are different than files with same names stored in HDD of MMC 103 . (difference in a size , even though I do not know if the size of the file which is displayed on the screen of Sinumerik should correspond with the size displayed in my computer ). How could I upload files from CD into HDD ? Vlado

Ekalavya Posts: 2964 Rating: (476)	Hello, Your welcome for your comments..... What is the alarm are you getting ??? provide us the details... Your machine is equipped mmc103 and it doesn't have USB... If your machine has floppy driver from there you cancopy your backups NC and PLC ... put the floppy in the floppy driver from there you can copy and paste in your harddisk form there restore the bacups... Hope these will solve your problem... Regards, Praksah

First , I will resume some information : 1. non working machine (sinumerik840D , MMC103, simodrive 611, NCU 572.2, 6 drivers in 3 double blocks ) the cause of the problem : - a bad working power supply unit 24V DC 2. I fixed power unit ( bad capacitor 100uF/35V replaced ) 3. After powering the machine on , digit 9 at the 7-segment display of NCU 4. General NC & PLC reset was made by S3,S4 switches of NCU (all data lost ) 5. Downloading NC and PC files from the archiv of HDD 6. The screen with these alarms : 3000 emergency stop 27000 axis X1 is not safety referenced 27000 axis Y1 is not safety referenced 27000 axis Z2 is not safety referenced 300950 axis X1 drive 3 is not safety referenced 300950 axis Y1 drive 4 is not safety referenced 300950 axis Z2 drive 5 is not safety referenced 700008 Pre warning temperature rise drivers 25201 axis A1 drive fault 300613 axis A1 drive 6 maximum permissible temperature 25001 axis A1 hardware fault of passive encoder 25000 axis A1 hardware fault of active encoder 300504 axis A1 drive 6 fault of motor transducer 300614 axis A1 drive 6 time monitoring for motor temperature I have to remind that Z2 and A1 are located in double drive and in a mean time - there was error red LED on ( all another drivers without of error LED ) Till this time I have not had any interest about hardware configuration of the machine . So , I wanted to know what wrong is with A1 axis. What I found was a bunch of 3 cables ( motor A1 , active and passive encoder of A1 ) not connected . I was informed , that this axis has not been used . (motor disconnected , active encoder disconncted ) Well , I suppose that I downloaded backup for some old configuration with A1 axis , but the machine was reconfigured without of A1 and a new backup was not created. (only my idea ) 7. I tried to find information how "to get rid off" A1 axis and I have found something about enabling/ disabling drive in machine data menu ( MD 30130 , 30240 , 30350 ) However , when I disabled A1 axis ( by changing some parameters and doing NCK reset ) , faults from 25201 - 300614 dissapeared , but all drivers have had error LED on . So , I do not know what to do , how to disable A1 . Any suggestion what I should do ? Thanks , Vlado Attachment drives.JPG (514 Downloads)
