3.5.3 Scaling and Offset
The defined areas and range of values of cam disks can be adapted in S7T Config
to meet the requirements of various applications. The function can be expanded or
compressed (scaled), and shifted (offset).

The scaling and offset of the cam disk can not be modified by the user program.
3.5.4 Interpolation
At a cam which is defined by means of polynomials and interpolation points, gaps
in the defined area can be filled by interpolation.
During interpolation of a cam disk
• the cam disk definition is verified to eliminate ambiguous values in the defined
area, for example
• continuity and marginal conditions are checked
• missing areas are supplemented.
Note
After interpolation, new polynomials or interpolation points can only be added after
resetting the cam with MC_CamClear.
During interpolation and in the continuity check, the properties of master and
following axes are neglected.
