Fanuc Oi Tc Programming Manual
Guys Does anyone have a parameter that can be changed which would coerce this miserable thing to reset the program pointer back to the top of the program in MEM mode when RESET is pressed? I mean, in my world if I hit RESET, I do so for a good reason, and absolutely have no intent to restart the program from wherever it happens to be. I've managed to get it to rewind in EDIT mode, but having to double hit the miserable softkey in MEM is just DUMB!!! Now the reason: This DUMB idiot mistakenly thought I was in EDIT mode when hit RESET, and in the belief that I'm back in the beginning, hit the green thingy. Plowing the threading tool 2' into the material. And it wasn't the first time similar thing happened, just the first time that I didn't catch it.

When M30 is executed in Auto mode the program rewinds to the Start because the M30 output is tied to Reset and ReWind (RRW).

The Reset Button is a momentary swich and the RST bit is monetarily turned on when the Reset Button is pressed. Accordingly, you could add an 'OR' rung to the ladder so that M30 'OR' RST turns on the RRW coil. Because RRW normally internally turns on RST, you would have to ensure that one didn't hold the other on indefinately; perhaps by using a timer in the RST 'OR' rung. Regards, Bill. Another stupid Fanuc convention. This exact scenario plays out here probably once a year with one of the operators, it's actually remarkable it doesn't happen more.
It would be one thing if it stayed on the same line when you hit reset, but it jumps a couple of lines forward, probably wherever the read ahead buffer was at or something. Bill, do you have any idea why the MTB's don't write the ladder by default the way you describe? I honestly can't think of a single reason why the Reset should behave the way it does, and I'm pretty sure every Fanuc I've ever used handles it the same stupid way.

Their control systems are made quite flexible for MTBs, and at the end of the day its the MTB that defines the character of the control in relation to the machine.
With many of the alternative setting options available via parameter, there are those who are going to hate either option. I also can't think of a good reason for not having the control rewind on Reset in Memory Mode; its not a difficult Ladder mod to implement.
It may have a lot to do with 'that's the way we've always done it'. Irrespective of how fool proof you may make a system, a suitably talented fool will always find a way to stuff it up.

Quite unfortunately, it sounds like the issue became purely philosophical, as I don't think ( don't know of a way ) that I can get into and modify Mori's ladder.
