In our example, the ANY pointer refers to a range of values of interpolation points
that begins at address 6 in DB10 and consists of eight interpolation points
(eight value pairs).

Data type Variable Function
0 REAL X1 X coordinate of the 1st interpolation point
4 REAL Y1 Y coordinate of the 1st interpolation point
8 REAL X2 X coordinate of the 2nd interpolation point
12 REAL Y2 Y coordinate of the 2nd interpolation point
... ... ... ...
REAL Xn X coordinate of the last interpolation point
REAL Yn Y coordinate of the last interpolation point
Disadvantage: The creation of cams based on interpolation point tables takes a
longer time, because a higher data volume is required for the cam description
compared with polynomial definitions.
Note
Firmware V3.1.x of the integrated technology
This firmware version allows you to add all interpolation points and polynomials of
an MC_CamSectorAdd command in a single command execution cycle. By
starting several MC_CamSectorAdd commands, you can also add more than 30
interpolation points, or more than 4 polynomials to the cam disk.
Note
Firmware V3.0.x of the integrated technology
With this firmware version, the interpolation points and polynomials are distributed
to several command execution cycles.
While a MC_CamSectorAdd command is busy, you may not start any further
MC_CamSectorAdd, MC_CamClear or MC_CamInterpolate commands.
