d1

Negative PID feedback from external terminal (AVI) 0 to +10V

 

d2

Negative PID feedback from external terminal (ACI) 4 to 20mA

 

d3

Positive PID feedback from external terminal (AVI) 0 to +10V

 

d4

Positive PID feedback from external terminal (ACI) 4 to 20mA

Select an input terminal to serve as the PID feedback location. Please verify the feedback location is different from the Frequency Set Point location and J1 for selecting ACI or AVI must be in the correct position. (Refer to Pr. 2-00 for detail)

Negative feedback = Positive target value – detection value.

Positive feedback = Negative target value + detection value.
