Periodic/Non-periodic Cam Operation(Periodic)
In the actual application of electronic cams, some may be executed periodically and some just need be
executed for one cycle. The Periodic parameter is used for choosing one of the two cases for the
electronic cam motion.
As Periodic=TRUE, the slave axis follows the master axis to periodically perform the cam motion till the
cam relationship is disconnected.
As Periodic=FALSE, when the end point of the cam cycle is reached after the slave axis and master
axis enter the synchronous cam motion, the cam relationship between the slave axis and master axis
will be disconnected and the slave axis will stop moving immediately.
If the velocity at the end point of the planned cam relationship is not 0, the slave axis will constantly
move at the disconnection speed after the disconnection of the cam relationship.
The impact of other instructions on cam operation
MC_CamOut
The MC_CamOut instruction can be used to end the cam operation which is being carried
out.
MC_SetPosition
The MC_SetPosition instruction has no impact on the being executed motion instructions.
