The conditions for starting cam operation are given in the following table.
Input variable
Periodic (Periodic Mode)
StartMode
StartPosition (Cam Table Start Position)
MasterStartDistance (Master Following
Distance)
For condition 1, the InCam (Cam Motion) and InSync output variables both change to TRUE and the
slave axis starts cam operation when the master axis passes 0°.
For condition 2, the InCam (Cam Motion) changes to TRUE when the master axis passes 0°. Then, the
InSync output variable changes to TRUE and the slave axis starts cam operation when the master axis
*1
passes 80° . For condition 2, cam operation starts in the middle of the cam table, so the slave axis will
accelerate rapidly.
