10.2.3 Free programmable linearisation
When you need to process the SSI encoder data and transform them into a
curve in the parallel output side (Linearisation), set the parameters as follows:
EXAMPLE
In the example a 16-bit SSI encoder provides 65,536 information to be
transformed into a programmable curve.

This programmable feature allows the user to convert a linear motion to a non-
linear parallel output and vice versa. There are 16 programmable interpolation
