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%
Parameter type: Range, 0 - 100%
Setup: All setups
Conversion index: 0
Data type: Int16
Change during operation: True
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.
).
