    Exclamation I need to disable the 4 axis - Fanuc 21-mb

    Hello, I have a Fanuc 21-mb machine and I need to disable the 4th axis - (A)
    I already tried to change the parameter 9900 - the machine does not allow to change, asks to restart it, does anyone know how to solve this problem?

    sorry for the translation, I'm from Brazil and there is no good forum like this one

    I think setting parameter 12.7 and 1005.7 to 1 for the A axis will do what you want.

    I did this procedure, the parameter 1005.7 was already set to 1 and 12.7 was not, when I do this, the alarm 401 appears - servo alarm : z axis vrdy off

    Are the Z and A axis on a common / dual axis drive?
    If they are what is the drive part number?
    There may be another parameter involved in case of dual drive.
