When the coordinate data corresponding to an input value that is 0 or when
the cam axis length per cycle setting does not exist, the coordinate is
calculated from the line segment between the nearest two coordinates.

CAUTION
If the cam data is set incorrectly, such as simply setting a target value and command speed
similar to positioning control, the position and speed command to the servo amplifier increases,
and may cause machine interface and servo errors such as "Overspeed" (error code: 2031) or
"Command frequency error" (error code: 2035). When creating and changing cam data, execute
a trial operation and provide the appropriate adjustments.
Refer to "Safety precautions" for precautions on trial operations and adjustments.
