Digital and Analog Inputs and Outputs
Option 5 (Feedback 1 of Main PID) configures the input to be used as the feedback 1 of the Main PID
Controller. The parameter P1026 defines its functionality in the feedback of the Main PID Controller.
Option 6 (Feedback 2 of Main PID) configures the input to be used as the feedback 2 of the Main PID
Controller. The parameter P1026 defines its functionality in the feedback of the Main PID Controller.
Option 8 (Feedback of External PID 1) configures the input to be used as the feedback of the External PID
controller.
NOTE!
In options 5 to 8, in case two or more analog inputs are selected for the same function, for instance,
P0231 = 5 and P0236 = 5, only the analog input with higher priority will be valid, being AI1>AI2, that
is, in this case the analog input AI1 will be the input used as feedback 1 of the Main PID Controller.
