5-38The target value can be entered using F01, Frequencysetting 1, or directly from the keypad panel.For entry from F01, Frequency setting 1, input a signal tothe selected terminal. For direct entry from the keypadpanel, turn on keypad operation. Select any of the digitalTerminals X1 (E01) to X9 (E09) and assign a value of 11(frequency setting switching).NOTE: For the target value and feedback amount, theprocess amount can be displayed according to the valuesset in E40 Display coefficient A, and E41 Display coeffi-cient B.H21 PID control (feedback signal)H 2 1 F B S I G N A LThis function selects the terminal, direction of operation,and feedback input. Select a value from the table belowaccording to sensor specifications.Value Description0 Terminal 12, forward operation, 0 to 10V voltage input1 Terminal C1, forward operation, 4 to 20mA current input2 Terminal 12, reverse operation, 10 to 0V voltage input3 Terminal C1, reverse operation, 20 to 4mA current inputOnly positive values can be input for this feedbackamount of PID control. Negative values (e.g., 0 to -10V, -10 to 0V) cannot be input, thereby the function cannot beused for a reverse operation by an analog signal.Feedback signal setting (H21) must be different from thetype of setpoint value.
