Fixed frequency mode

(Fixed frequency mode)

0 ... 1

{ 0 }

This parameter determines the form in which fixed frequencies are to be processed.

0 = 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 = As main setpoint: (No addition / Fixed frequency is the main setpoint value) Fixed

frequencies are not added - neither together, nor to analog setpoints.
If for example, a fixed frequency is switched to an existing analog setpoint, the analog
setpoint will no longer be considered.
A programmed frequency addition or subtraction to one of the analog inputs or bus
setpoints is still possible and valid.
If several fixed frequencies are selected simultaneously, the frequency with the highest
value has priority (E.g.: 20>10 or 20>-30)

In the array levels, up to 15 different fixed frequencies can be set, which in turn can be encoded
for the functions 50…54 in binary code for the digital inputs.

[-01] = Fixed frequency 1 / Array 1

[-02] = Fixed frequency 2 / Array 2

[-03] = Fixed frequency 3 / Array 3

[-04] = Fixed frequency 4 / Array 4

[-05] = Fixed frequency / Array 5

[-06] = Fixed frequency / Array 6

[-07] = Fixed frequency / Array 7

[-08] = Fixed frequency / Array 8

[-09] = Fixed frequency / Array 9

[-10] = Fixed frequency / Array 10

[-11] = Fixed frequency / Array 11

[-12] = Fixed frequency / Array 12

[-13] = Fixed frequency / Array 13

[-14] = Fixed frequency / Array 14

[-15] = Fixed frequency / Array 15

{ 0.0 }

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 .
