Parameters I Like to Change
Category : Fanuc Parameters
Messing With Parameters Can Be Fatal!!!!!
If you have worked on many Fanuc controls like I have you will know that there are massive differences in the way they operate. No it’s not because they were not all created equal. It’s just the dreaded parameters.
Now I can’t stress enough how important it is not to mess with the parameters of a machine. So don’t.
Please Proceed If You Are Stupid
Maybe your not stupid maybe you actually want to wreck your CNC Machine so you chose to carry on.
Once I have set these parameters the machine almost performs how I want it to.
These are not machine options that you pay for or anything like that. They are just choices as to how you want the control to work.
Point of No Return
First of all you’ll need to go to the setting screen and change the parameter write box to a 1.
You will need to be in MDI to do this and all the subsequent alterations.
Please note that these parameters wont necessarily be the same on all machines so please check your parameter manual.
This stops that annoying alarm when you reach the end of travel on the various axis.
1401 Cutting Feed-Rate 0% stops movement of machine
When proving out I like to use the feed rate override control to stop rapid moves as well as feed moves.
3202 Unlock Program 9000 to 9999 and 8000 to 8999 to Edit
I often need to acces the 9000 series program and this allow me to do it.
This parameter will clear the MDI screen each time it is used.
3401 Calculator Type Decimal Point or Integer
This parameter will determine if you need to add a decimal point to your X Y Z numbers.
6005 Allows the Use of Local Subroutines (Newer Control)
I love local sub routines, this parameter means M98 Q500 will jump to internal program N500
3301 Allows you to make screen shots
I use screen shots all the while they are really useful for keeping a record of the different screens especially parameters so do yourself a favour and use this one
That’s it away you go.
Oh just one other thing before you go off and cripple your machine forever.
Do yourself a favour take a picture of the screen before you change a parameter. If you aint got a camera then you must have a piece of paper.
Even better back everything up.
Thanks
