The cam table settings are the same as in the previous example. The conditions for starting cam oper-
ation are given in the following table.

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) and InSync output variables both change to TRUE and the
slave axis starts cam operation when the master axis passes 40° (the value that is specified for
StartPosition (Cam T
able Start Position)).
