Today we are going to change the parameter that sets all the modal G codes when you first turn on your machine. This is often known as the wake up state.

Power Up Fanuc Parameter How it works?

When you switch on your machine certain G codes will be active. But what G codes are active?

Well…. they are whatever you set in this parameter.

Imagine you just typed in X50. Y50. in MDI and pressed cycle start. Would it rapid, feed or try and go around in an arc?

In parameter 3402 the different bits set the G codes that are active when you first turn on your machine.

#0 G01 (Set to zero you wake up in G00 set to 1 you wake up in G01)

#1 G18 (Set to zero you wake up in G17 set to 1 you wake up in G18)

Isn’t it just great to sort out those annoying problems?

Things like the machine waking up in incremental can be a potential disaster.

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 ain’t got a camera then you must have a piece of paper.

Even better back everything up on a regular basis.

Unlock Programs Fanuc Parameter 3202

Tags : Fanuc Parameters

Category : Fanuc

Messing With Parameters Can Be Fatal!!!!!

Unlock Programs Fanuc Parameter, first of all you’ll need to go to the setting screen and change the parameter write box to a 1.

Programs 9000 to 9999 are used for things like probing, tool-change and all sorts of other important things.

So beware back em up ASAP.

These programs along with 8000 to 8999 can be locked so no one can mess with them.

3202 if NE9 is 1 then programs 9000 to 9999 can’t be deleted or edited.

3202 if NE8 is 1 then programs 8000 to 8999 can’t be deleted or edited.

Once you’ve finished don’t forget to lock the 9000 programs back up and turn off that parameter write switch.

Unlock Programs Fanuc Parameter 3201

So you might want to use this yourself if you have a sub program in your machine that you use quite often and you don’t want anyone messing with it.

Don’t forget when this parameter is set to stop you editing the programs you can’t read them in and out either. That means you can’t back them up until you unlock them.

Parameters You may Need to Change

1300 Stops over travel alarm

1401 Cutting Feed-Rate 0% stops movement of machine

3101 Clear Screen

3203 Clear MDI Screen

3204 Unlock Program 9000 to 9999 and 8000 to 8999 to Edit

3291 Wear Offset requires Key to Adjust

3401 Calculator Type Decimal Point or Integer

3402 G Codes that are Active When The machine is Turned On

5003 Retain Geometry when you Press Reset

6005 Allows the Use of Local Subroutines (Newer Control)

6050-6059 Allows you to Call a 9000 series Program with a G Code

6080-6089 Allows you to Call a 9000 series Program with An M Code

8134 3453 allows you to use ,R and ,C (Rads and Chamfers)

That’s it away you go.

Oh just one other thing before you go off and cripple your machine forever.

Decimal Point Fanuc Parameter 3401

Category : Fanuc

Messing With Parameters Can Be Fatal!!!!!

Decimal Point Fanuc Parameter, to change this parameters you need to go to the setting screen in MDI. Now put a 1 in the parameter write box.

Today we are going to change the parameter that allows us to program with or without a decimal point.

Decimal Point Fanuc Parameter

If you set parameter 3401 BIT 0 (DPI) to a 1 then you can input numbers like a calculator.

X5000 will be taken as 5000mm

If you set parameter 3401 BIT 0 (DPI) to a 0 then your numbers will be taken as microns..

X5000 will be taken as X5 (in other words 5000 microns you would need to program X5000. to get 5000mm

X5000000 would also work

This should make it work. If it doesn’t then maybe you should call the Samaritans.

Decimal Point Fanuc Parameter Why?

It doesn’t really matter how you set this it’s entirely up to you. What I would recommend is that you make all your CNC machines behave in the same way.

Teach everyone to always input a decimal point and then if it’s needed then you got it.

Parameters You may Want to Change

1300 Stops over travel alarm

1401 Cutting Feed-Rate 0% stops movement of machine

3101 Clear Screen

3102 Unlock Programs

3203 Clear MDI Screen

3204 Unlock Program 9000 to 9999 and 8000 to 8999 to Edit

3291 Wear Offset requires Key to Adjust

3401 Calculator Type Decimal Point or Integer

3402 G Codes that are Active When The machine is Turned On

5003 Retain Geometry when you Press Reset

6005 Allows the Use of Local Subroutines (Newer Control)

6050-6059 Allows you to Call a 9000 series Program with a G Code

6080-6089 Allows you to Call a 9000 series Program with An M Code

8134 3453 allows you to use ,R and ,C (Rads and Chamfers)

That’s it away you go.

This guy has more CNC Manuals than you can shake a stick at.

Oh just one other thing before you go off and cripple your machine forever.

Offset Keylock Fanuc Parameter 3291

Messing With Parameters Can Be Fatal!!!!!

Offset Keylock Fanuc Parameter, before you change this you will need to go to the setting screen in MDI.

From here you can allow yourself to alter parameters.

Put a 1 in the parameter write box.

Today we are going to change the parameter that stops operators from altering wear offsets.

Offset Keylock Fanuc Parameter

Apprentices should be inquisitive it’s normal. We want them to experiment and learn by making mistakes.

Mmmm sounds great but and there is a big but. By a big but I don’t mean a big arse I mean but with one t.

I once trained an apprentice on a Haas VF1. He picked it all up really fast. When I revisited he was really excited to show me how he’d learned to alter parameters all over the place.

It was real scary stuff he thought it was fuckin space invaders or some computer game.
