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
S Number of fixed setpoints:
S Selection of fixed setpoints:
– Binector input bits 0, 1, 2 and 3 = 0 –> setpoint = 0 active
– Unused binector inputs have the same effect as a "0" signal
