5.10.23 Writing a Cam Point
1. Motion control function block
The motion control function block T_CamWrite is used to modify a particular point in a cam chart. The
value of the CAMTable input pin indicates a cam chart. The value of the CamPoiontNo input pin
indicates a cam point number. The value of the MasterPosition indicates the position of the master axis
specified, and the value of the SlavePosition indicates the position of the slave axis specified.
