(9) Check the supply gas pressure.
Check that the secondary pressure of the gas regulator is
0.175±0.025 MPa.
(10) Turn on the power, then check the operation of the fan motors in
the housing.
The fan motors installed in the oscillator start turning as soon as
the power to the CNC is turned on. Check the operation of each
fan motor. Note, however, that the fan motor installed in the laser
power supply does not start until the oscillator sequence starts the
turbo blower operation.
(11) Check the parameters and setting data.
A parameter table for the laser oscillator is attached to the
oscillator. Some machine builders prepare a parameter table
including parameters for the laser oscillator. If data sheets are not
found, contact the machine tool builder.
(a) On the setting screen of the CNC, set the parameter write
enable state.
(b) Check the parameters, and enter the same values as
specified in the parameter table.
(c) On the setting screen of the CNC, set the parameter write
protected state, and press the reset button.
CAUTION
1 If the oscillator is started with an incorrect
parameter value specified, the oscillator may fail in
the worst case. Be particularly careful when
entering and checking parameter values.
2 Some parameters may require modification to, for
example, suit the operating state of the oscillator or
enable maintenance. When parameters are
modified, it is recommended that modification
history (date, parameters before modification,
parameters after modification, and reason for
modification) be recorded so that old parameters
and invalid parameters are not used.
3 Be careful not to lose the attached data sheets,
and keep them safely.
(12) Check that cooling water is supplied normally, and that there is
no water leakage inside the oscillator or at any external
connection points. (See Subsection 3.3.3 for details.)
Check that the temperature of the cooling water is set to 20 to
30°C.
