P464 Fixed frequency mode

0 ... 1
[ 1 ]
This parameter determines the handling of fixed frequencies. With addition, simultaneously
controlled values are added together. Otherwise, each value is output separately, whereby with
multiple control the highest frequency value is always output.
0 = Addition to setpoint value
1 = No addition / fixed frequency is setpoint value

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 8.2.

Switch on/off delay
S
-30.000 ... 30,000 s
[ 0.000 ]
Adjustable switch-on/switch-off delay for the digital inputs. Use as a switch-on filter or simple
process control is possible.
[-01] = Digital input 1
[-02] = Digital input 2
[-03] = Digital input 3
[-04] = Digital input 4
Positive values = switch-on delayed
Negative values = switch-off delayed
