8.7 LASER POWER CONTROL
Overview
When a difference is detected between the actual speed and the
programmed speed in a corner portion, for example, the laser power
control function adjusts the peak power, pulse frequency, and pulse
duty ratio to achieve uniform machining.
When the laser power control mode, described later, is selected by a G
code or external signal, the power, pulse frequency, and pulse duty
ratio are controlled to maintain the following relation:

Pulse duty ratio
Mo : Power, frequency, or duty ratio when feedrate F is 0,
specified in a parameter
Mmin : Minimum power, frequency, or duty ratio, specified in
a parameter
Mc : Power, frequency, or duty ratio in laser power control
mode, specified by a program
Fc : Feedrate in laser power control mode, specified by a
program
