Basic configuration of PID control
Pr. 128 = "10, 11" (deviation value signal input)
Set "0" to Pr. 868 "Terminal 1 function assignment". When Pr. 868 ≠ "0", PID control is invalid.
Fig. 5-260:
● Pr. 128 = "20, 21" (measured value input)
Note that the input of terminal 1 is added to the set point of terminal 2 as a set point.
Set "0" to Pr. 858 "Terminal 4 function assignment". When Pr. 858 ≠ "0", PID control is invalid.
