I have a Mori Zt2500 with a MSG-501 control. Running Fanuc. We got he machine and the upper turret/main spindle does not show the X axis on the display screen just Z, Y, 5(turret). The lower turret displays X,Z,5,A like it should . I don't know what parameter to change to have the X displayed. They had issues with the turret and i believe the changed it to display that and not the X but didn't switch it back.
