Parameter 7-44 Process PID Gain Scale at Max. Ref.
Table 475: Parameter 7-44 Process PID Gain Scale at Max. Ref.
7-44 Process PID Gain Scale at Max. Ref.
Default value: -100%
Conversion index: 0
Enter a scaling percentage to apply to the process PID output when operating at the maximum reference. The scaling percentage is
adjusted linearly between the scale at minimum reference (parameter 7-43 Process PID Gain Scale at Min. Ref.) and the scale at maxi-
mum reference (parameter 7-44 Process PID Gain Scale at Max. Ref.).

Description
Select which drive input should be used as the feed-forward factor. The factor is added to the
output of the PID controller. This increases dynamic performance.
This option is only available in FC 302.
This option is only available in FC 302.
Selects a fieldbus reference configured by parameter 8-02 Control Word Source. Change parame-
ter 8-42 PCD Write Configuration for the bus used to make the feed forward available in parame-
ter 7-48 PCD Feed Forward. Use index 1 for feed forward [748] (and index 2 for reference [1682]).
