We have an old mazak T2. The machine is alarming out on occasion. The Fanuc AC Spindle Servo Drive is showing the Alarm 1 led lighted. The display shows alarm 204. That tells you to clear the alarm and cycle the power. I want to know what the alarm LED 1 is telling me on the drive. Can anyone help me with this. Our manuals tell me nothing about the controller. I would appreciate any help or input.
Thanks,
David Snyder
