Details
Set the cam resolution for generating the cam.
Set the required input amount with the cam per cycle.
Set the reference value for the stroke amount
specified by stroke (Yn).
When the cam stroke amount units are "%", this is
ignored.
Set the display unit of the cam axis length per cycle,
and the unit for cam stroke amount in hexadecimal.

Set the starting point as the point corresponding to
"cycle length = 0" of cam data.
Set the number of sections of cam data.
Set data for the number of sections specified.
Set the cam curve.
Set the point for cam axis length per cycle (cam axis
*1
position value per cycle).
It is necessary to set a value larger than the end point
immediately before (Xn < Xn + 1). Also, for the final
end point, set as the cam axis length per cycle.
Set the stroke position from the cam reference
position of when at the end point specified by cam
axis position value per cycle.
Set the curve applicable range (start point: P1, end
point: P2) for the cam curve. Set so that "P1 < P2".
When "P1 = P2 = 0", "P1 = 0" and "P2 = 100" are
applied.
Set the acceleration/deceleration range (L1, L2) for
the cam curve. The range that can be set differs
depending on the cam curve. When "L1 = L2 = 0", the
default value for each curve is applied.
