PROGRAMMING18. SPECIFYING THE LASER FUNCTION
B–63664EN/02
340
Whether the laser power control function is to be enabled or disabled can
be specified using the laser setup screen or a parameter.
1) Specification using the laser setup screen
The laser power control function is enabled by setting the power
control item on the laser setup screen to 1.
S Power control (on the laser setup screen)
1: The laser power control function can be used.
0: The laser power control function cannot be used. When this value
is set, laser power control mode, described later, cannot be set.
2) Specification using a parameter
The laser power control function is enabled by setting bit 0 (LPC) of
parameter No. 15000 to 1.
S Bit 0 (LPC) of parameter No. 15000
1: The laser power control function can be used.
0: The laser power control function cannot be used. When this value
is set, laser power control mode, described later, cannot be set.
Any of the control items, peak power, pulse frequency, and pulse duty, can
be selected using a parameter (PRM.15096). More than one item can be
selected.
If none of these items is selected, no power control is performed.
The power control function uses the nozzle feedrate to calculate each laser
output factor (peak power, pulse frequency, and pulse duty). To get hold
of this feedrate accurately, you must specify which machine axis is related
to the operation of the nozzle, using parameter No. 15089.
If this parameter is omitted, the first and second axes are assumed to have
been set up.
An axis subjected to simplified synchronization control is related to the
movement of the nozzle. This axis, together with the master axis, should
be excluded from the setting.
If the laser power control function is enabled using the laser setup screen
or the appropriate parameter, the peak power, pulse frequency, and pulse
duty can be controlled in proportion to the feedrate by specifying G63P1.
The system is returned from laser power control mode either by
specifying G63P0 or by entering a reset signal (laser power control mode
is canceled).
