hello, i have a mazak 8g cnc lathe, and i cant get the z axis to move, when it is powered up it comes on as normal with no alarms, when put into a handle mode you can turn the wheel and the numbers on the position screem move as normal but the table(gang tool lathe) wont move, i replaced the limit switch and it does work, but if it jogs at any speed it will alarm out with a z axis servo overload. i called mazak and they dont really know what to say. this machine is late 80's. anybody have suggestions
