(3) The range from the last point of cam data to the cam axis length per cycle
When "the last point of cam data [Cd.617] Cam position calculation: Cam axis position value per cycle < cam axis length per
cycle", the position corresponding to "[Cd.618] Cam position calculation: Cam axis command position value" is searched from
the last point of the cam data or later.
If the corresponding position is not found even though the range of (3) has been searched, "Cam position calculation cam axis
1 cycle position value calculation disable" (warning code: 0EB4H) will occur in reciprocating cam pattern.
For the feed cam, calculate "[Cd.618] Cam position calculation: Cam axis command position value" by the stroke difference
and search the whole range from the 0th point again. If the corresponding position is not found even though the search
process starts again, "Cam position calculation cam axis 1 cycle position value calculation disable" (warning code: 0EB4H)
will occur.
When "[Cd.617] Cam position calculation: Cam axis position value per cycle" is corresponding to the last point of cam data
