APPENDIXG. ALARM LIST
4054 E CODE DATA ERROR The specified E code value is beyond the allowable range.
4055 E CODE NOT COMMANDED Because no E code is specified, a laser output calculation cannot be
4056 OPT. PATH NOT SET In constant optical path control, the mirror block position cannot be
calculated with the current positions of the axes. Perform reference
4060 TRACE ERROR EXCESS In gap control, the nozzle is brought too close to the workpiece.
4061 A/D CONVERTER–1 A/D converter 1 (for reading power and gas pressure) on the laser
interface board does not perform conversion normally.
4062 A/D CONVERTER–2 A/D converter 2 (for reading voltage and current) on the laser interface
board does not perform conversion normally.
4063 RF POWER SUPPLY The R/F power supply in the laser oscillator becomes abnormal.
4065 SHUTTER ACTION The mechanical shutter in the laser oscillator does not operate normally.
4066 DISCHARGING At the start of discharging of the oscillator, discharging could not be
4067 LASER CABINET OH The temperature in the oscillator has exceeded a specified level.
4068 BEAM REFLECTION The beam reflection from the workpiece has exceeded a specified level.
4069 LASER IF PCB The laser interface board is not connected. Alternatively, the laser
interface board is abnormal.
4070 CHILLER NOT READY No ready signal has been received from the chiller.
4071 ASSIST GAS NOT READY No ready signal has been received from the assist gas supply unit.
4072 CHILL FLOW The flow rate of water supplied to the oscillator is insufficient.
4073 LASER GAS PRES. The laser gas pressure supplied to the oscillator is too low.
4074 OXIGEN DENSITY The oxygen concentration in the oscillator exceeds a specified level.
4075 CHILL TEMP. There is dew condensation in the oscillator. The water temperature is
4076 LASER POWER DOWN The laser power lowered from the average value of commands by a
specified value or more.
4077 ABSORBER TEMP. The temperature of the absorber has exceeded a specified value.
4078 LASER TUBE PRES. The laser gas pressure has exceeded the range of (100 (1 = 13Pa) of
the set value.
4079 PUSH RESET KEY The emergency stop button was pressed. Release the emergency stop
state, then press the reset key. This message is issued when an
emergency stop state is entered in the stages from LRDY to LSTR.
4080 LASER TUBE EXHAUST At RUN–ON, a specified gas pressure cannot be obtained by
exhaustion within 10 minutes.
4081 GAS PRES. CONTROL The laser gas pressure is not within the range of (20 (1 = 13 (P) of
the set value in 45 seconds after the start of gas pressure control.
4082 TUBE PRES. SENSOR The value from the negative pressure sensor is 0.
The negative sensor may be faulty, or there may be a cable
4083 SHUTTER NOT OPEN Although the shutter was not open, a laser output command was
4085 MIRROR CLEANING Because the output compensation coefficient has exceeded a specified
value, clean the mirrors.
4087 SHUTTER OH The shutter temperature has exceeded a specified level.
4088 LASER VOLTAGE DOWN The discharging tube voltage has lowered below a specified level.
4089 ASSIST GAS NO SELECT Although assist gas was not active, a laser output command was
4090 LASER NOT GENERATE Although the oscillator did not generate oscillation, a laser output
command was issued.
4091 INVERTER The inverter for the blower is abnormal.
4093 BLOWER GREASE Because vibration in the turbo blower has increased, change grease.
