Problem- Custom Macro A alarm 76

[Lene Madsen]

Hi all!

I hope some of you can help me deal with a problem I get when I make a program in Custom Macro A for a Fanuc O-MD, 3-axis milling machine.
My problem is that when I try to run my program (posted at the bottom) I get alarm 076 address P not defined.
I have tried to define my P#values both at the main program, in variables definition of main program and later I tried to define them in the subprogram. Neither seemed to get rid of the problem, and since I haven’t been able to find much help on macro A I seem to be stuck.
The program has to drill 9 holes (3x3) in each of 8 parts that are lined up as 4x2
I am new to CNC programming so it might be some very basic knowledge I’m lacking. I really hope someone can help!

Thanks!

Regards,
Lene Madsen

Dear Lene,
Could you tell me result of try as follows(Delete or skip M,S,T code and insert M30 at the end of Main program).
(M6 T1);
(G00 X0 Y0 Z0,5 S400 M13);

I answered your post last night, but I don't see it here this morning. Not sure what happened there.

Anyway, the format you're using to define P is correct with User Macro A. In the following example, P would take on the value of Q, being 4000

G65 H01 P#121 Q4000

When a program contains macro statements, and the control alarms for no obvious reason due to something related to the Macro statements, try isolating a line of code that the error message relates to, in a program by itself and try running it. For example, construct the following program and run it.

O1000
G65 H01 P#121 Q4000
M00
M30
%

1. If the program errors and displays the same error message that you have been experiencing, then you have an issue with the control because the code in the above program is viable.

2. If the program runs without an error, and when it stops at the compulsory stop M00, look up variable 121 in the Macro variable register and check that the value 4000 has been stored in the corresponding variable.

3. Continue to add to this program one block at a time, the blocks from your original program, but include the M00 just before the end of the program.

4. After each inclusion of the additional block, run the program to see if you get the error and check the variable as in point 2 above.

This may sound a bit tedious, but when you have an error situation that is occurring for no obvious reason, this is a good way of finding the cause, particularly when the program is relatively short as yours is.

Please post the result if you decide to run this test.

Bill

Or if you are just learning CNC programming then you may want to use macroB instead. This is more current with machine programming then A. I am never against learning something no matter how old it is but it is definitely 2 breeds of programming and macroB will help you longer term. You will also find more support to B then A. I am taking nothing away from the people already helping and their suggestions.

Sorry I know read the rest of your post with the macroB code. May I ask why you were advised to write this in macroB first?

Can anyone tell that I hate macroA??

Sung and Angelw:

I will be trying both your suggestions once the machine is off duty, thank you very much both!

Stevo1:

The particular machine I am running only has the option to program in macroA.
I was adviced to write in macroB since they mostly differ on syntax. Is that wrong?

The syntax of Macro B is very much like Basic or Pascal and is quite intuitive and relatively easy to read. Macro A, on the other hand, uses codes to represent functions and accordingly, you have to know what the codes represent to be able to read the program.

In the following example the two Macro statements have the same function, but the Macro B code is far easier to read.

Macro A------------------------------Macro B
G65 H02 P#101 Q#102 R15------------#101 = #102 +15

I can well imagine someone suggesting you write the program in Macro B, then transpose the Macro A function code to perform the same task, because of the better readability of Macro B. However, the same could be achieved by drawing a Flow Chart, which is the approach taken when designing software.

The attached picture is an example of a flow chart just to illustrate how symbols, lines, and directional arrows can be used to show functions, conditional statement etc in a graphical, easy to follow form. Flow charts are often just quick hand sketches to allow you to better visualize the logic of your program.

Bill
