I talked with Fanuc today about this problem and Dick Swisher in parts was aware of exactly what you want to do.

He said an option is available to solve your problem.

You still use the G10 method

Sorry for re-posting that.

When you call and get connected to anyone in parts just ask to be transfered to Dick

I was actually able to talk to Dick, but he said that because it was a wire
edm that the functions were likely different. I must contact the importer,
Methods machine.

I'll post if I ever get a straight answer....

Thanks for all your help..

I've never heard of a method for changing parameters from a program on a Fanuc. If there is such a feature, it's not documented.

Dan you are the Fanuc MAN how can you not know this? It is a usefull function when you got a couple of EL's in the shop that constantly think they know best. I have several Parameters that I force a value to. Here is the part of the Manual for the 18I that exsplains it. What I would like to know is are you familure with L60 or L61 function. I see that our Kittamuras are using these functions in a few of there programs and I am not sure what they are doing.

Well .... ahh .... ahem .... Thanks for the compliment (I think). I do know a bit about Fanucs, but my knowledge is mostly from the "olden days" when I worked for General Numeric. The latest & greatest controls back then were the Fanuc sysems 6, 10, 11, and 15 series, and they've come a long way since then.

The feature to change system parameters with a program command really is new to me. I'm a bit surprised that Fanuc would permit such an intrusion into the inner workings of the control. With the earlier Fanuc models, all you could do is read macro system variables (axis position, current feedrate, etc.). You couldn't write to them, nor could you change system parameters unless you were reading them in through a tape reader or a serial port. The only feature that I remember that came close was was a command to program the "safe zones", or programmable overtravel limits.

It would make sense to use a feature like this if you needed to adjust servo acc/dec rates or limit rapid rates under program control. I can imagine situations where an enormous pallet gets loaded onto a machine by a cell controller and the inertia of the X and Y axes changes dramatically.

I definatley meant it as a compliment, I learn quite a lot from reading your post as I am sure lots of us do. I see you help out a bunch of folks. I have been in this CNC game since the Yasnac B and C controls with the LED readouts way before Zero returns and all that easy stuff. And I have had exspierienc with every Fanuc with the exception of the 15I and the new 30I. It is a fun game and I enjoy it emensly. except right now I am stuck in a real low tech job. The Delphi Plant I was at is going down so I transferd to a facility where I am supporting 58 year old transfer lines. Quite a shock. But I will give the old guys credit they still make good parts.

Thanks for making it informative, Bluesman

Hello,

I know this is an old thread, just found it. I have the same control on an EDM. I am cutting some SST rings and I get wire pinch. I am wondering if you know of a way to after the machine detects wire break, instead of the machine trying to travel back through the cut it just made, to have the machine start cutting from the beginning of the program. This would ensure the cut is made. I do not mind the extra cycle time.

Thanks!
