ALM No.4067
LASER CABINET OH (detected by the C2000-E only)
The temperature of the input side of the electrode cooling fan is
monitored and sends alarm when it exceeds 60
°C.
When the temperature decreases below the prescribed value, the
alarm state can be solved by resetting. Before that, it cannot be
solved.
Alarm output condition
This alarm is issued if the "temperature in the cabinet" signal becomes
"0" after the start of the oscillator and immediately before the completion
of purging.

BEAM REFLECTION
This alarm is issued, if a workpiece reflects laser beam more
than the rating to the laser oscillator. This can happen when the
laser beam is used to drill, cut, or weld materials (such as copper,
brass, and aluminum) having a high reflectivity to the laser beam
(10.6
µm).
Alarm output condition
This alarm is issued when the actual laser output is in one of the
following conditions at the time of beam output:
(1) The actual laser output is higher than the average command power
(power × duty) by more than the value set in parameter No. 15265.
(2) The actual laser output exceeds the value set in parameter No.
15266.
The actual laser output is not monitored for five seconds after the beam
is turned on or the output is changed.

LASER IF PCB
This alarm appears when there occurs the anomaly in the
stabilized power unit voltage +5,
±15, +24V of IF PCB for NC
interface.
Alarm output condition
The enable signal in the IF in the IF PCB becomes "0" and this alarm is
issued when an error occurs in the stabilized power unit voltage (+5V,
±15V, +24V) after the start of the oscillator and immediately before the
completion of purging.
