: Interpolation data record
The
interpolation data record
are the data words which are necessary to perform the
interpolation algorithm. The number N of data words in the record is defined by
interpolation
data configuration
. The interpretation of the data words in
interpolation data record
may
vary with the different possible interpolation modes as set by the
interpolation sub mode
select
.
For the linear interpolation mode each interpolation data record simply can be regarded as a
new position set-point. To describe a cubic spline interpolation e.g., four or more data words
are needed for the spline coefficients, and further interpolation parameters.
After the last item of an
interpolation data record
is written to the devices input buffer, the
pointer of the buffer is automatically incremented to the next buffer position.
