    Daewoo Puma 240 rapid override stuck at F0 or 50%

    We have a puma 240 with fanuc 18 control.
    Our problem is that the rapids will not go past 50% and while on 50% the led is blinking.
    Can anyone help on why the machine will not go into 100% rapids. I have turned off the tailstock and checked the touch setter inputs for up and down.
    Thanks

    Could be that the OP soft key is over ridding. There is an software operator panel under one of the mode keys.

    Door interlock?

    Touch setter would cause "no travel" in the direction of the problem, if it were the issue. (so that's probably not it.)
    The fact that, when you have it set to 100% rapid you get a different action than when you have it set at 50% (i.e. flashing switch or non-flashing switch LED...so that's probably not it.)

    The lack of tailstock extended, or at home position could give the same issue you are experiencing, check those switch's inputs for function.
    Is the "Dry Run" switch functioning correctly and in the correct position, as it makes rapids slower.

    If you check those and they are correct, give me the ladder version and I'll look into it further.

    Every time I have seen this in the past it was switches on the tail stock If I remember right it has always been the switch that shows that the tail stock is clamped

    Tail stock. Easy fix, don't bother calling a tech.
