This parameter determines the form in which fixed frequencies are to be processed.
0 = Add main set, "Addition to main setpoint": (Addition of the fixed frequency to the main
setpoint) Fixed frequencies and the fixed frequency array are added to each other. I.e.
they are added together, or added to an analog setpoint to which limits are assigned
according to P104 and P105.
1 = Equal main set value, "Equal to main setpoint value": (No addition / Fixed frequency is
main setpoint) Fixed frequencies are not added - neither to each other nor to the analog
setpoints.
For example, if a fixed frequency is switched to an existing analog setpoint, the analog
setpoint is no longer taken into account.
However, a programmed frequency addition or subtraction to one of the analog inputs
or bus setpoints remains possible and valid.
If several fixed frequencies are selected simultaneously, the frequency with the highest
value applies (e.g.: 20>10 or 20>-30)

In the array levels, up to 31 different fixed frequencies can be set, which in turn can be encoded
for the functions 50…54 in binary code for the digital inputs.

With the aid of the minimum frequency process controller the control ratio can also be kept to a
minimum ratio, even with a master value of “zero”, in order to enable adjustment of the
compensator. Further details in P400 and Section 9.2.
