B-63662EN/01 8.LASER OUTPUT CONTROL
- 55 -
• Valid data ranges
The valid data ranges are as follows:
Ramp UP/DOWN step distance : 0 to 65.000 mm
Step power : 0 to 7000 W
Ramp UP/DOWN operation is performed by measuring the
distance of the straight line from the machining start point to the
machining end point in a single cutting block.
• Number of steps
The number of steps in which the laser power is changed in step
control is 10. This number is fixed.
• Step control mode
In a machining program, step control mode is set by specifying
command E301 to E305. Step control is canceled by specifying
E300. Only the laser power is changed in step control mode; the
other machining conditions set with the previously specified E1
to E10 commands remain as is.
• Step distances
The ramp UP and DOWN distances cannot extend over multiple
blocks.
• Power override
Power override is effective for the laser power output in step
control.
• Operation on arcs
For an arc, step control is possible if the distance of the straight
line from the start and end points is longer than the sum of the
ramp UP and DOWN distances.
A full circle, on which the start and end points are the same,
does not satisfy this condition and, therefore, step control is not
possible. If, however, the circle is divided in a machining
program, step control can be performed on each part of the full
circle.
Limitations
• This function is an option function, and requires the following
separate functions:
1) Option function, "machining condition setting function"
2) Option function, "expansion retention type memory add
function"
• This function can be used to its full advantage when used with
the FANUC C series laser.
• This function cannot be used with the automatic corner override
function, edge machining function, and startup machining
function. The step function takes precedence.
