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.
Ramp UP step distance Ramp DOWN step distance

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.

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.
