A setpoint can be entered via the analog inputs, the serial communication
interfaces, the JOG function, the motorized potentiometer as well as also using
fixed frequencies. The fixed frequencies are defined using parameters P1001 –
P1015 and selected via binector inputs P1020 – P1023, P1025, P1026. The
effective fixed frequency setpoint is available via connector output r1024 which
means that it can be connected further. If this is to be used as setpoint source, then
either parameter P1000 or P0719 should be modified or BICO parameter r1024
should be connected to the main setpoint P1070 or supplementary setpoint P1075.
Contrary to parameter P0719, when parameter P1000 is modified, this implicitly
changes BICO parameters P1070, P1075.
Example:
3 methods are available when selecting the fixed frequencies.
Direct selection
In this particular mode, the control signal directly selects the fixed frequency. This
control signal is entered via the binector inputs. If several fixed frequencies are
simultaneously active, then the selected frequencies are added.

The fixed frequencies can be selected via the digital inputs as well as also via
serial communication interfaces. The fixed frequency is selected, when using digital
inputs, using 2 techniques. This will be shown in the following example using the
fixed frequency P1001 and digital input 1 (refer to Fig. 3-36).
