3.5 "Cam disk" technology object
Use the "Cam disk" technology object to implement complex
motion structures. A "Cam disk" defines the dependency
between the slave position and the position of a leading axis.
A cam disk describes a position-specific transmission behavior between a control
value source such as a virtual positioning axis or external encoder (input variable)
and a following axis (synchronization axis, output variable.)
The "Cam disk" technology object is configured in S7T Config. The cam profile can
be defined in S7T Config or in the user program.
• The cams are created in S7T Config, based on interpolation points or
segments. Use the Scout CamTool or CamEdit programs to apply the cams.
• The cam can be defined in the user program, in the "MC_CamSectorAdd" and
"MC_CamInterpolate" technology functions. Before you do so, reset the cam
disk by executing the "MC_CamClear" technology function.
