Messing With Parameters Can Be Fatal!!!!!

Power Up Fanuc Parameter 3402. To change 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 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?

Even better back everything up on a regular basis.
