P3.13.2.9 SETPOINT 1 BOOST (ID 1071)
Use this parameter to set the multiplier for the setpoint boost function.
When the setpoint boost command is given, the setpoint value is multiplied with the factor
that is set with this parameter.
10.14.3

FEEDBACK

P3.13.3.1 FEEDBACK FUNCTION (ID 333)
Use this parameter to select if the feedback value is taken from a single signal or combined
from two signals.
You can select the mathematical function that is used when the two feedback signals are
combined.
P3.13.3.2 FEEDBACK FUNCTION GAIN (ID 1058)
Use this parameter to adjust the gain of the feedback signal.
This parameter is used, for example, with the value 2 in Feedback Function.
P3.13.3.3 FEEDBACK 1 SOURCE SELECTION (ID 334)
Use this parameter to select the source of the PID feedback signal.
The AIs and the ProcessDataIn are handled as percentages (0.00-100.00%) and scaled
according to the feedback minimum and maximum.
NOTE!
The ProcessDataIn signals use 2 decimals.
If temperature inputs are selected, you must set the values of parameters P3.13.1.5 Process
Unit Min and P3.13.1.6 Process Unit Max to correspond to the the scale of the temperature
measurement board: ProcessUnitMin = -50 °C and ProcessUnitMax = 200 °C.
P3.13.3.4 FEEDBACK 1 MINIMUM (ID 336)
Use this parameter to set the minimum value of the feedback signal.
P3.13.3.5 FEEDBACK 1 MAXIMUM (ID 337)
Use this parameter to set the maximum value of the feedback signal.
10.14.4

FEEDFORWARD

P3.13.4.1 FEEDFORWARD FUNCTION (ID 1059)
Use this parameter to select if the feedforward value is taken from a single signal or
combined from two signals.
You can select the mathematical function that is used when the two feedforward signals are
combined.
Accurate process models are usually necessary for the Feedforward function. In some
conditions, a gain and offset type of feedforward is sufficient. The feedforward part does not
