G. ALARM LIST
4094 VANE PUMP The vacuum pump is abnormal. A thermal trip occurred in the magnetic
contactor because of overload on the vacuum pump.
4095 A/D CONVERTER–3 A/D converter 3 (for reading gap displacement) does not operate
normally. Check the analog input board in the CNC.
4096 UNDER TRACING With the gap control axis selection function, an attempt was made to
switch between axis selection signals during gap control.
4097 TRACE AXIS SELECT With the gap control axis selection function, no gap control axis
selection signal is selected, or more than one gap control axis selection
signal is selected.
4098 TRACE AXIS & PLANE With the gap control axis selection function, plane selection is specified
for the gap controlled axis.
4099 GAS PRES. NOT REACH When the base discharge state is entered, the laser gas pressure has
not reached a specified pressure level.
4100 INVERTER 1 Blower inverter 1 becomes abnormal.
4101 OUT OF FREQUENCY 1 The inverter frequency has not reached a specified level within 120
seconds after turbo blower 1 was started.
4102 OUT OF VIBRATION1 Vibration in turbo blower 1 was detected.
4103 T.B NOT STOPPING 1 The rotation speed of turbo blower 1 has not lowered to a specified level
within 120 seconds after RUN–OFF.
4104 TURBO OVER CURRENT 1 An overcurrent alarm was issued in turbo blower 1.
4105 TURBO TEMP. 1 The temperature of turbo blower 1 has exceeded a specified level.
4106 BLOWER OIL SHORTAGE Lubricant in turbo blower is insufficient.
4107 MIRROR NOT INSTALLED The folding mirror is not mounted.
4110 INVERTER 2 Blower inverter 2 becomes abnormal.
4111 OUT OF FREQUENCY 2 The inverter frequency has not reached a specified level within 120
seconds after turbo blower 2 was started.
4112 OUT OF VIBRATION 2 Vibration in turbo blower 2 was detected.
4113 T. B NOT STOPPING 2 The rotation speed of turbo blower 2 has not lowered to a specified level
within 120 seconds after RUN–OFF.
4114 TURBO OVER CURRENT 2 An overcurrent alarm was issued in turbo blower 2.
4115 TURBO TEMP. 2 The temperature of turbo blower 2 has exceeded a specified level.
4116 BLOWER OIL TIM LIMIT Turbo blower oil has been used for a longer time than the replacement
Because there is a possibility that the turbo blower is damaged, change
oil as soon as possible.
4124 OVER COOL Even when warm–up operation is performed, the temperature of the
oscillator cannot increase to a specified level or higher.
4129 SHTR OPEN IN DISCHRG The shutter was opened during discharging in the oscillator.
4130 STEP TIME NOT SET The step time for high–speed piercing is not set.
4131 INCORRECT STEP DISTANCE
In step control, the rest of travel distance becomes shorter than the
ramp–down distance before the ramp–up distance is completed.
Alternatively, the ramp–up distance cannot be completed within one
4132 PARAMETER WAS CHANGED. The setting of parameter No. 15223, 15242, or 15243 was changed.
4133 TRACE DEC. POSITION The gap control displacement observed at the start of gap control is
smaller than the deceleration start deviation (parameter No. 15848).
Sufficient deceleration for the gap controlled axis may fail, which can
cause a collision with the workpiece. This alarm is not issued if bit 2 of
parameter No. 15840 is set to 1.
4134 PRG. ERROR FOR TRACE A move command for the gap controlled axis was issued from the
machining program during gap control.
4135 PULSE PFB DATA ERROR Because the pulse power feedback table data read through a memory
card or reader/punch interface was incorrect, the read operation was
4136 INTERNAL PRESSURE TOO HIGH This alarm is issued when the pressure inside the laser gas mixer
becomes too high (1MPa).
