I have a problem with an old Beyeler machine RTS63/1200.

It is with Cybelec control DNC-7000. It has a problem with initialization and it is not possible to access parameter pages 8, 9, 10. Do somebody have a software for this type of control and any idea how it has to be installed?

Or may be at least some manual in English?

Any help will be highly appreciated.

When your EURO4/DNC70 PSG controller only shows video information when started in keyposition 3, what should one start looking for?

The beast has blank screen when started in other keypositions - but when started in pos.3 it reacts on the L, P, N, C and main menu buttons, but further actions are mostly rejected - message:"Ignored" or no response...

We are allowed to choose local language and some other options, but the use of the machinery is still quite limited. The initialization procedure described in the user manual did not help. Backup battery holds 3V, the other static RAM replaced, ..

Hope somebody with repair experience on this unit will give a helping hand. Schematics and functional descriptions of system is too much to hope for, I guess ...

The controller works with a Beyeler press brake.

Best regards

1 How do I enter the menu without the key for the key lock( to put it on position 3 - machine initialization ). There are 4 contact on the back of the key lock with 2 diodes anodes connected togeather and 3 wires connected to the rest of the contacts.

2 There is exactly same working machine in the neighbourhude so I can read all the necesary parametars is this OK.

3 Can You send me the initialization procedure in English - please

Thank you, Bent

I'm pretty new to CNC. We own a Durma press brake machine with cybelec Cybelec S-CNC-CA04PSE2 controller and ModEva10S as display panel. Currently we facing intermittent problem with vertical axis (Y-axis)movement. After some diagnosis we notice that during auto mode the controller not supplying voltage to proportional valve. But no problem with manual mode. To futher analyze the situation we need to access to the CNC logics, I believe this will help to see what condition stopping the vertical axis. Could you advice how actually we can view the logics?

thanks.

We brought to Dominican Republic a Beyeler with CNC7300PS.

in the time of transportation the battery ran out then we have to introduce the parameters, now the controller boots ok, when we press the green start button I feel the noise on the valve but the beam is not moving at all. I dont know is is a wrong parameter or if is some mechanical problem. what do you think?

With the power off test how hard it is to turn, if it is hard to turn then that is the problem

guessing its still the pressure differential in the valves..which were changed to proportianal valves ..

and also still have to sets of controls for the machine looking to part with..

two controls cybelec dnc 90/900 with extra boards and one with working monitor and track ball.. motoarmour@gmail.com

thanks for all the help here hope someone could use these spares.. the are collecting dust..

Can you tell me how ro initialize the machine? it's a weinbrenner with dnc900.

Also i get an error when i go to "bend numerical" and try to bend - the error is "negative face lenght".

Thank you.

best regards

I have a problem with DNC with CPU1202 board,

in the bios I set the value of the memory video to "None", after restarting the ModEva console longer displays anything, I connect a VGA screen on the vga mainbord connector, but nothing displayed.

if you can help me solve this problem.

I try to remove the battrie located on the motherboard during 12 hours but without result.

thank you for your help.

i have the Motherboard type: Cybelec CPU1202-board (LX800 processor or VE400) with XP Embedded

sorry for the long issue, but i was really busy in the last months.

1. you already have the problems ?

2. if yes, please tell me what type of pressbrake you have... servovalve controled machine or torsion pressbrake

3. the machine do the preset operation without problems ?

4. check the input for external 24 V !

hello simo,

also sorry for the long issue...

ok i understand your problem, i will ask to get some informations to help you... i'll give a answer in the next days...

i should tell you to initialite the machine ?! OK

1. turn machine on and start the pump

2. if the dnc is boot up, go on automatic mode and press the start button

3. the ram goes up and the stops drive to their preset points

4. if the preset is finshed, the red led in the green start button goes off, of this not the case, we have a problem...

5. press the green start again and the axes will move to their programmed postions, after that you can bend

your problem : its sounds like the product is not programmed finished or has some incorrect values...

check this in that you go the page "product numeric"... here you will see a table with the values for your piece you wanna bend... check this values if they are correct or delete the whole values and program your piece in "bend numerical"...

thats all for now...

you say the ram will move in manual mode, but not in automaic mode... pls check with the electric diagramm the circuit for the fast closing part of the ram, normally in that you have some safety conditions in it, like the watch signal for the fast move down valves...

to get acces to machine parameter of the dnc, you must press "ALT" (first and hold it) and then "3"... normally a window will pop up where you must enter the code for this level... this is in standard "333"... xou can check your level, in the right bottom corner of your display... to get acces to the levels press ALT + 1 or 2 or 3... the code is the level three time "111, 222, 333"

thats all for now...

i know this problem from other controls... i think the only thing you can do is to reset the dnc...

for this turn the machine off, turn the key switch to position 3 and turn the machine on...

normally you will get a screen where you see a page with lines like "

[_] Zone variable, etc...

and on the bottom you must enter a code...

okay on this page you will delete the whole memory of the dnc, but mostly after this the dnc works fine... before you do this, check if you have a backup from your machine parameters, thats really important, because the problems come from this...

if have this type a "1" in the line [_] zone machine paramters, or something like that, nor sure cause its maybe that the language on this screen isi in french...

then type the code in the line for it : 817

after that turn off the machine and switch it on again... therefore turn the switch key to "1"... if the dnc boots up, turn the switch key on the dnc to 3 and type your backup paramters line for line in... after this you will get normally access to ypur missing pages... if this not the case, maybe we have hardware problem...

thats all for now...

My cnc bending machine is "donewell" with "cybelec" control (year 1984)

i want replace its control panel with a new HMI, so I need to know the cybelec "servo switching amplifier" tech. info

thanks

for this i need to know what servo amplifier is mounted in your machine... also i need the type from your dnc and the type from ypur servo valves, after that i can send you a pdf file what you need !

thats all !

MB

the servo amplifier is called " servo switching amplifier SVC 206"

no data about DNC type

solenoid

ATOS

DIS 83655

DHS-9-71-9

380V AC delta

1450 RPM

Our controller is a

Cybelec V-DNC-1200/B

DNC 1200 PS/B

Does anyone have information regarding the hdd on this, as we need to replace it, i believe it is a solid state drive if this helps
