Fixed speed setpoints

Description
This function can be used to specify preset speed setpoints. The fixed setpoints are defined
in parameters and selected via binector inputs. Both the individual fixed setpoints and the
effective fixed setpoint are available for further interconnection via a connector output (e.g. to
connector input p1070 - CI: main setpoint).
Properties
● Number of fixed setpoints: Fixed setpoint 1 to 15
● Selection of fixed setpoints: Binector input bits 0 to 3

– Binector input bits 0, 1, 2 and 3 = 0 -> setpoint = 0 active
– Unused binector inputs have the same effect as a "0" signal
