Default G68 G69 for 1985 VA 55 II won't work

I work for a company that recently purchased a 1985 Hitachei Seiki VA 55 II with FANUC controls. I need to use programs that a 2007 model cnc using FANUC has generated with lots of variables and subprograms.
My superviser does not understand enough to know that the existing programs for a 2007 FANUC will not work on a 1985 FANUC.
I will use G68 and G69 extensively on sprockets. I am not able to get G68 to work, the error tells me that G68 is not an acceptable G code.

Need help with Macros to program without the aid of a computer.

example........... repeat the same 3" straight line cut multiple times with a .08 step depth each time for multiple tooth sprocket. (the size, number of teeth, length of cut, and location change for each sprocket configuragion)

No computer............. I asked, no go....... old school only.

Am I completely SOL?

Robert:
Tell your supervisor that programs from old Fanuc controls usually work in newer or brand new controls, but it does not work the other way.
If your controls says something like "Illegal or Unknown G-Code", it means you do not have it.
If you have software to generate programs, you should be OK.
You do have Subprograms and you may have the Macro option.

I have taken programming classes for CATIA, it is not available here. The VA 55 II is stand alone and will not be hooked up to a computer anytime soon. I have to program with the controls only............takes a long time to repeat the same cut 7 times.........can you show me how to use a short macro with G91 rather than my first instinct of cut and paste with Notepad.............controls only programming.

But do have macro option available on your machine?
Execute #500 = 1; in MDI mode, and see if the machine accepts it. Then the macro variable screen should show 00001.000 stored in #500.

What model Fanuc control are you using? Also as Sinha has stated let us know if you have macro programming on the control by trying what he suggested. This will help us determine the best way to program your passes. And no worries it can be done.

I MDI'd "500 = 1;" Got illegal spacing alarm. Is "Execute" part of the comand? Real tough to type words with control panel.
I looked at the soft button "C.A.P." it brought up a page that states the C.A.P. is not available.
I had to go through that button to find the 1-500 page of macro's.

Stevo, not sure what model, how do I find the page that would tell me the FANUC model.

It is not 500=1, rather it is #500=1.
Better still, try #500=SIN[30] and see if variable number 500 stores 0.5.
You have to use square brackets here.

The model of the control is usually on the front of the control. If not in the power cabinet there should be a sticker located either on the main board or some moduals depending on the model machine. It should tell you the model and serial number.

As Sinha has stated you have to use # symbol before the 500 and you then have to use your ; symbol or EOB then insert that code and press cycle start. So it should look like this #500=1; No spaces when typing this.

You should not have to go to CAP to view your #500 variable. It should be under settings. You may have to push settings a few times until it is under the section labeled variables. This is why knowing the model control would be helpful because then we could tell you the exact sequence of buttons you have to push.

#500=1 shows up in MDI as #500 =1 and I get an illegal spacing alarm, I'll try #500=SIN[30] on monday.

Inside the cabinet there is a metal plate with

FANUC SYSTEM 11
TYPE A0215-0076-13501
NO 1485 1985-10


FANUC is on the front of the monitor.

There is not a variable screen in settings, got about 5 other screens by hitting settings multiple times but, no variable screen.

You have to insert semicolon (referred to as EOB, end-of-block) also:
#500=1;
Even then if you get an alarm, you do not have macro option enabled on your machine.

Default Re: G68 G69 for 1985 VA 55 II won't work

I don't think I have macro's on this machine, it alarms out for "#500=1;" and "#500=SIN[30] as well. I tried both MDI mode and inside a short program. Both gave me an error when the controls turn the command into #500 = S I N [30] by adding spaces when inputted into program or MDI.


can anybody tell me what is wrong with this program,


O0016;
G58;
M3 S500;
G0 X0 Y0 Z6.0;
G1 X-7.727 Y0 Z6.0 F11.0;
G68 X0.0 Y0.0 R0.0;
G1Z-.1;
X2.0 Z.01;
Z.1
G69
G1 X-7.727 Y0.0;
M30;
%

I'm just trying to test G68, I get an error when the G68 command is run.
I copied, and adjusted from a program for a 2007 FANUC.

How do I turn the G68 command on, it shows up in the Manual provided for the machine.

G68 may not be available on your control. Fanual manual contains all possible codes.

In G68 X0.0 Y0.0 R0.0; X0 Y0 is center of rotation, and R0 is rotation angle in degree (it has to be different from zero). Is your groove of varying depth?

What is the error that you are getting on the MC when it reads the G68? As Sinha has stated all codes are in the manual but some are options that may or may not have been activated.

The alarm is PS010 IMPROPER G-CODE....................

I don't think we have this nor macro's on this machine.

I tried changing R0.0 to R20.0, still got the same alarm.

Do I have any options other than wait for a computer to be hooked up?
