■Master axis absolute coordinate
The following explains the operation at MasterAbsolute set by MC_CamTableSelect.
• [0: Relative coordinate] is specified to the master axis absolute coordinate
MasterSyncPosition becomes the start point of the cam data. When InSync turns TRUE, cam operation is executed
corresponding to the relative movement amount of Master.
Cam operation is executed continuously, even when ring counters of Master and cam table are not matched.
Ex.
Master axis: Ring counter of the current value: 0 to 360.0000 [degree]
MasterSyncPosition: 180.0000 [degree]
Cam: Cam length per cycle: 540.0000 [degree]

■Slave axis absolute coordinate
The following explains the operation at SlaveAbsolute set by MC_CamTableSelect.
• [0: relative coordinate] is specified to the slave axis absolute coordinate
When InSync turns TRUE, the slave axis starts the operation of the cam profile from the current position (set position).
When the periodic mode of the cam profile is set to [1: Periodic], the next cycle starts from the stroke position (set position)
where the last cycle completed.
