FANUC lathe M-codes

MarkGilson · Mar 15, 2018

My lathe is controlled with FANUC series oi-Mate TD and i can not find an accurate M-code list. I have 6 books that came with it and there isn't a list in any of them.

I've found a few lists online but they are not for my series (M21 unclamps the jaw on mine)

I'm mainly just looking for air ON-OFF and chip conveyor ON-OFF if it has one.

Any help is appreciated!

Who is the machine builder? They right the ladder logic.

the Lathe is a Mighty Viper VT17L

M codes beyond M0, M1, M3, M4 are machine builder assigned. Look for them in your Mighty Viper manuals.

This, or you are just going to have to experiment and make your own list.

Like the time I discovered that M76 mirrored the Y axis on our 6MB.

N76 mistyped M76. Drove me nuts!

That's a good one! Probably wore out a bald spot with the head scratching that required.

@OP:

As others have posted most M codes are machine builder defined. Inputting random M-codes to see if anything happens or to try to determine what they may do is not without some risk. Some machine builders use M codes to put the machine into various states for maintenance or adjustment. Often this includes turning off interlocks or safety logic. In most ladder programs, re-booting the control will reset back to correct condition, but not in all cases. Your best solution is to get the proper M-code list from your machine builder.
