EXAMPLE:
A Setpoint Generator with the following pattern:
Fig 4.31.1 - Pattern for setpoint generator
In order to represent this curve of 17 points, two blocks are necessary. If the Setpoint Generator
block is configured with
CLIN=9, the blocks 109 and 110 shall be configured as shown on the Table
4.31.2.

Table 4.31.2 - Points of the Curve
It is recommended to program the last point of the curve with the maximum value possible for the
input (X). To be in the safe side, it is good to program the last X with 102% and the last Y with the
appropriate value.
