3 Axis Command Instructions
Periodic (Periodic Mode)
If you specify TRUE (periodic) for Periodic, the cam motion will be repeated from the start to the end
point of the cam table.
If you specify FALSE (non-periodic), the cam operation ends when the last point in the cam table is
executed.
If the stroke position of the slave axis is the same at the start and end points of the cam table when
TRUE (periodic) is set, the cam operates as a reciprocal cam. (Refer to Reciprocal Cam Operation.)
If the stroke position of the slave axis differs at the start point and end point, the cam operates as a
feeding cam. (Refer to Feeding Cam Operation.) In the following chart, the horizontal axis indicates
the master axis and the vertical axis indicates the slave axis.

EndOfProfile (End of Cam Cycle)
EndOfProfile (End of Cam Cycle) is TRUE for one period when the command value of the cam
motion for the phase and displacement defined by the end point in the cam table is output. Set the
absolute position of the master axis as the StartPosition (Cam Table Start Position) and the cam
table becomes relative to that position. EndOfProfile (End of Cam Cycle) functions as an output indi-
cating the end of the cam table.
