PROGRAMMING18. SPECIFYING THE LASER FUNCTION
The laser output increases because
the reference feedrate lowers.
Override changed (large to small value)
Reference feedrate Fc after
override is changed
As the feedrate becomes
steady, the original laser
output level is restored.
Actual feedrate and laser output (2)
When an F command is specified in the power control mode, the reference
feedrate is assumed as follows as in the case where the override is
When bit 5 of parameter No. 15096 is set to 0
The reference feedrate is not changed.
When bit 5 of parameter No. 15096 is set to 1
The reference feedrate is changed to the value specified with address F.
(G code specification)
(If controlling the power specification, pulse frequency, and pulse duty)
Both Mo and Mmin are assumed to be 0.. . . . . . . . . . . . . . .

Before issuing G63P1, you must specify a machining
condition that corresponds to Mc shown in Fig. 18.3.
Specification using E codes
(When the power command, pulse frequency, and pulse duty cycle are
When an E code for cutting is specified in a program, the corresponding
cutting conditions are searched for, and if the conditions include a power
control condition setting, the power control mode is entered.
In the following example, the E001 command enters the power control
mode, and the E003 command cancels the power control mode.
