Description of Parameters
Figure 8-33: PID Sum Point Reference
374 Analog input supervised value 7 (P1.3.2.15)
The value of the selected analog input to be supervised by ID373.
375 Analog output offset 67 (P1.3.5.7, P1.3.3.7)
Add -100.0 to 100.0% to the analog output.
376 PID sum point reference (Place
A direct reference)
5 (P1.2.4)
Defines which reference source is added to PID controller output if PID controller is
used.
0 No additional reference (Direct PID output value)
1 PID output + AI1 reference from terminals 2 and 3 (e.g. potentiometer)
2 PID output + AI2 reference from terminals 4 and 5 (e.g. transducer)
3 PID output + PID keypad reference
4 PID output + Fieldbus reference (FBSpeedReference)
5 PID output + Motor potentiometer reference
If value 5 is selected for this parameter, the values of ID319 and ID301 are
automatically set to 13. See Figure 8-33.
Note: The maximum and minimum limits illustrated in the picture limit only the PID
output, no other outputs are affected.
