In many ways, Macro Programming is the highest level of G-code Programming. It offers the most flexibility and the greatest potential power of any of the G-Code Programming Techniques. Not all controllers support full Macro B, and there are variations supported by some non-Fanuc controllers. Until now, all of our g-coding has been done without any recourse to variables or formulas.
If we wanted to go to a particular coordinate, we had to enter that coordinate, either absolute or relative, to get there. A tremendous amount can be accomplished in that way, but just as algebra is more powerful than arithmetic, so parameterized programming is more powerful than basic g-code, and for the same reasons. Once you have variables, you can start to parameterize your programming. Imagine being able to create your own custom canned cycles that can do almost anything. A custom drilling cycle, or perhaps a routine to automatically serial number your parts.
Almost anything is possible. Covering the whole of parameterized programming will involve three chapters in our tutorial. The next chapter will delve into how to divide your code up into subprograms and access the subprograms. Not all controls support parameterized programming. You may have noticed that different companies often make the CNC Controller versus the actual machine tool.
In fact, this is nearly always the case. There are a collection of settings inside the controller that are called parameters that are used to perform that configuration of the controller to the machine tool. For example, the travels, spindle speed range, rapid traverse rate, and many other types of information that are critical to making the control work right with the machine. You should make sure you have a good backup of all your parameters in case the battery fails on the controller or they get inadvertently changed.
Typically there is a procedure available for your controller to use DNC to perform a backup. First thing is first, what are variables? Simply put, they are just like algebra variables that you can use in your g-code. They can be assigned values, and when you refer to them, they give back the last value they were assigned.
The syntax for a variable is the pound sign followed by a number up to however many digits your controller supports that identifies the variable.
The variable 0 always has a null value, and you can give any other variable a null value just by assigning 0 to it. For example:. These variables fall into ranges that affect their meaning and how they can be used. Here is how Fanuc thinks of these ranges, for example:. Fanuc Macro Variables: Note that these ranges may vary across controllers and especially for non-Fanuc controllers!
Mach3 has 10, variables available, from 0 to Use variables whenever you think you might want to change a value in different situations. For example, suppose you have a macro or subprogram that cuts a square pocket.
You probably want to have variables that let you define the size of the square and the feeds and speeds so they may vary as the material changes. Depending on the subprogram, you might want a variable for the top left corner of the square, or you might simply let that corner be the current position when the routine is called.
You may want a variable defining the depth of the square pocket. And lastly, you may want a variable that defines the diameter of the tool. System Variables and Local Variables have some special behaviors, so steer clear of those unless you specifically want those behaviors.Learn more about Scribd Membership Home.

Quick navigation Home.I am always amazed that when people ask for a variable to do something, a lot of you know this stuff. Im not amazed that you know it, I'm amazed that there seems to be some super secret document out there that shows what a lotmaybe most, of the system variables do.
So I ask. Is posting this list for the group a violation against fanuc? We have thousands of users in this forum. I think everybody came across a problem one time where they needed a variable, then they found it and posted it As far as the list 1 I dont think is a good idea to write a list hundreds because of copyright issues 2 Even if you write one, we wouldnt be able to keep track.
There are thousands and thousand of variables. Another problem may arise from the disclosure of information from the manuals that belongs FANUC without their consent may not be disclosed. I really like this idea. I've discovered a couple of nice ones just through experimentation. Other ones I've found out from some one "in the know". Do a control-F for them in the system variables document? I would like to see a list of variables that are not in the current documentation, with a blurb of the theorized or observed affect of the variable is.
How could Fanuc claim copyright when the variable in question is not in their documentation? You could categorize them so searching through them is easier.
These variables directly affect the mechanical unit. These affect the motion planner. It would be far better than how Fanuc organizes their system variable document plain A-Z. I agree with Nation. Knowing some of these variables can make our life so much easier. This one saved me already a lot of hours troubleshooting.
I think everybody should post usefull variables so we can list them. Reading a couple of parameter-related topics, among this one, I notice a lot of the answers can be found in the manuals or documentation supplied by Fanuc.
I had about the same questions, sent an e-mail to our Fanuc representative and got all the information I needed. I have to admit that not all information is in the standard docs, and as standard Japanese companies are not so very keen on handing over all technical info about there creation However so far it has never been a problem getting the right documentation in the right way from the right source.
Maybe there's a difference in policy about this we are a Dutch Fanuc integrator thus dealing with Fanuc BeNeLux but anyway. System Variables for RiB. I honestly believe if your company has a Fanuc robot registered to them, all you have to do is call spare parts and they will set you up with an account for free. Also if you have ever taken a Fanuc class you can get access. I took a class last summer and the access the students are given on the cRc site is far less than I already have working for an official integrator.
I don't know if the access they are given includes access to manuals, I would guess not. Seeing as they only took a class, not buy a robot from Fanuc. Like you said though if you can show you own a robot you should have good luck getting access.Name: Allen-Bradley Interface Configuration.

Smart Options and Accessories.Imagine this: you have a robot that easily keeps up with its task trust me, these applications do exist! The robot works its ass off for a few seconds and then sits there motionless, waiting for the next part to come down the line.
You try putting up signs. You hold a special training session on robot happiness to no avail. The next step is locking the teach pendant away in a cabinet. All of this could have been avoided if you or your integrator took control of the robot override properly. One issue with this is that it will not prevent people from changing the override while the robot is running.
Lucky for you, FANUC has another feature that lets you configure four different overrides based on a couple of input signals. I am fairly certain that this is a standard option at least here in North Americabut I could be wrong.
The function itself is pretty self-explanatory: two user-defined DIs control the override based on a setup table when the feature is enabled.DIY - Tutorial - Quick mastering procedure using a Teach Pendant from a FANUC robot.
The function is only in effect while the robot is in AUTO. You will still have control in teach mode. The issue with this is, of course, that you only get four override values. In all honesty this should be more than enough, but a lot of times people want even more control.
Reason 1: you can only use this statement to set the override to the value of a register, constant or argument register. Reason 2: if you accidentally send a real number e. The error should probably indicate a type mismatch instead, but this is what you get.
Reason 3: this statement cannot be used in a Background Logic program. NOTE: The scaling factor is out of Of course you could just modify all your segment speeds, but who wants to do that? I never set the override within my process TP programs. The other one will not allow you to select a GI as the value.

There's more where that came from.The funny thing is I have another page that does have the icons, and the review box does pop up.
If I make a version of your link with my Google page (to go right to the review), NOTHING happens. You just get my page. I have been into Settings. Nice write up Travis, I was just figuring this out the other day after Google slammed Local and thus shut down our old approach.

For those following this article, I have found a way to include a direct link for leaving a mobile review. I am still working out a few of the details, but I hope to have it complete soon. I tried different links to Business Google pages, but this is HANDS DOWN the most direct and best method. Why is Google so ignorant not to place these instructions in their help pages. Do you know of a fix for this. Hmm Without being able to duplicate it, I cannot trouble-shoot it.
My guess is that the issue lies on your computer with a improper clearing of the cache or something else similar. Sorry to give such basic suggestions, but as I mentioned above, I cannot troubleshoot the issue very well, if I cannot replicate the issue.
Thanks for the quick response. Same result after clearing Cache, in latest versions of Chrome and IEWhat browser are you using. I just tested in the newest versions of Chrome, Firefox and Internet Explorer. I am having the same problem as Jay. I am sorry but your link isnt working as stated. Your business page comes up and then an empty white box appears where I am assuming the review would go but there is no writing in it. I also attached the link you directed to my business url and it didnt work either.
