HI- I have an Okuma ES V 4020 mill and I need to reset our G30 Pxx home positions and lost the instructions for exposing the nc optional para's.. I remember it was something like setting bit 7 of para 16 but i can't remember the exact steps- anyone know how to do this?

In other words- when the machine does a tool change, it moves to a predefined Z position, and then it travels to an X and Y postion. I want to get rid of the XY move because the part i am doing is very tall and there is a chance of a crash. I know how to change these parameters, but for some reason they have been made invisible. I am sure there is a way to unlock paramaters but nobody seems to remember how and the notes have been long since lost..

NC Optional Parameter Bit line 16 bit 7 set to 1 opens the System Parameters.
