*1 The set value is only used for cam data generation. Control is performed by the output axis parameter "[Pr.439] Cam axis length per
cycle".
*2 Refer to the following for the shapes of each cam type. Use P1 = 0, P2 = 1.00, and default values for L1 and L2.

*3 If setting is outside range, the cam axis length per cycle will be set as the final end point of the section settings.

Details
Set the cam resolution for generating the cam.
Set the required input amount with the cam per cycle.
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 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.
When set at "1000000000", it becomes the position set in "[Pr.441]
Cam stroke amount".
The data specified by "number of sections" becomes valid.
It is not necessary to set the data after the specified number of
sections.
