Deckel FP4NC

[MWeesenaar]

Hi people,

I am working with a Deckel FP4NC with a Dialog 4 terminal and I am wondering if there is any way to replace this interface for a PC or a laptop.
I guess there will be programs somewhere which can communicate with the PLC as if it is the terminal.

Could anyone give me a hint or something about what I can do.

Kind regards,
Mikki.

Hi,

I just bought a Deckel FP5NC with Dialog 4 stearing. While plucking it down for the transportation we disconnected the computer from the mashine. I had a couple of days with it before the rest of the machine arrived. I noticed that (When i took the hood of) the axis are on four dedicated boards. while the sensors probably is on a separate one as well. but i havent confimed this the io board yet. When i saw this i got the same thought as you, to replace it with a bit newer computer (our's from 1986).
My plan is listening in on the pin's to figure out the comunication to the servo controllers. I guess it's some kond of pulse communication and i guess it's not that complicated. but i haven't got any experience with servo controllers yet so i might be wrong.

I googled quite a bit but found none that has replaced the dialog4 with anything else. It might be that dialog4 is all we need, but the thought of depending on a 25 year old computer isn't a good one. If you get any futher on this please post a post.
or if anyone else has any information on the communication please do post.

I know Sentner Machine tools will put a heidenhien on it for you. We have or had a lot of old Deckels here, the controls are OK when they work. We even have a super rare Hurco-Deckel. I would think it wouldn't too hard to dump all the control, and still use the bosch drives. I would for sure dump the PLC. Those are were we have most of our problems. You probably could just use a siemens logo module for the new PLC, not much on those machines.

Dear Sir,

How r u?

I have one CNC machine. Complete detail with model is given below:

Machine Model: 64V Linear.

Machine Maker: Deckel Maho

Machine controller: Heidenhein iTNC530

In this machine I m facing one problem of I leak Led at power supply UV 123. That problem solved and now I have new alarm on the machine.

When I ON the machine and after complete CNC system booting. Machine gave “relay ext. dc voltage missing”.

When I ON the drives the all drives gave READY green LED. But after few seconds all drives off and machine at LCD screen gave alarm of

C3B0 Motor X does not rotate or some times it’s gave C380 Motor X not controllable.


Please give me the technical guidance to resolve my problem. Drive model is UM113.

I have no any manual and electrical drawing.

Hope you give me positive response.

I suppose the old controllers Dailog-4, with FP4NC are Obsolete but quiet robust.
I fail to understand , whether replacing these controllers would ever be a great idea ? instead it would be a better idea to mantain these controllers.
I had a quote from Centroid (from their Indian agents/integrator) , they say we will not supply controller only , but all the DC motors, Drives also need to replaced with AC Servos & Compatible drives & Total cost of retrofitment goes USD 15000 ?
also by employing this advance controllers it will not be possible to do any highspeed milling OR complex 3d profiles on this mc
Is it worth spending this amount on retrofitment of FP4NC ? or is there any low cost option

Could anyone suggest a maintenance support for Dailog-4 ,

If you have a dialog whatever control in your machine, use it as long as it works. If one of the controllerboards are defective then you can try to change only the controller. All these old machines have the +/- 10V interface for the drives. The tacho of the motor goes to the drive, therefore it can have the feedback. But you need a replacement for the Heidenhain DRO as well. The old parts have a 11µA currentinterface, which can not read with any modern control. Some controls have a 1,1Vpp interface, for this you need a small amplifier that you can build DIY from some OPamps, or you buy it for a price in the range of 150-200$ each from HH.

I think a retrofit of only the controller will be not really much more expensive, (because you need only 3 or maximum 4 axes) than the repair of an old controller board. And you can wait, til the next board will defective.
