If an alarm occurs, the alarm number and message are displayed on
the CNC screen.
CHECKING ON FAULTS
After identifying the following items, call the FANUC service center.
In some cases, a symptom is not actually a fault in the oscillator,
although it looks like a fault. So, check it with the following sections.
(a) State of operation
(machining in progress, oscillator being started, etc.)
(b) Timing of a fault (alarm)
(c) Alarm number
(d) How often the fault occurs
(e) Oscillator serial number
(2) Other information
(a) Software system and edition indicated on the CNC screen
when power is turned on
(b) Parameter settings;
check the current parameter settings with the corresponding
values indicated on the unit, and report your finding to the
FANUC service center.
