8.7 STEP FUNCTION
The step function controls the laser power in steps for a set distance,
starting from the weld start point and for another set distance ending
at the weld end point when welding is performed with laser beam
machining, to achieve good welding results. The figure below shows
an outline of the ramp UP/DOWN distances and power control. The
laser power is changed in ten steps over each of the set distances.

Distance
The ramp UP step distance multiplied by 10 is called the ramp UP
distance, while the ramp DOWN step distance multiplied by 10 is called
the ramp DOWN distance.

Explanations
• Setting the machining conditions
The data area provided for the step function is capable of storing
five data item sets, each set consisting of the data items listed
below. E301 to E305 are allocated as the E numbers for
specifying the individual data items.
a) Ramp UP step distance b) Ramp DOWN step distance
