I have a Supermax lathe with Fanuc O-T controls and I am getting an alarm that requires powering down and restarting to clear. The alarm message is:
1005 Spindle Alarm
409 Servo Alarm(serial err)
The board has AL-04 on it.
The problem seems to be getting progressively worse, as the alarm is happening more frequently.
If anyone is familiar with this issue I would appreciate any advice you can offer. Thank you.
