The target value can be entered using F01, Frequency
setting 1, or directly from the keypad panel.
For entry from F01, Frequency setting 1, input a signal to
the selected terminal. For direct entry from the keypad
panel, turn on keypad operation. Select any of the digital
Terminals X1 (E01) to X9 (E09) and assign a value of 11
(frequency setting switching).
NOTE: For the target value and feedback amount, the
process amount can be displayed according to the values
set 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 L
This function selects the terminal, direction of operation,
and feedback input. Select a value from the table below
according to sensor specifications.
Value Description
0 Terminal 12, forward operation, 0 to 10V voltage input
1 Terminal C1, forward operation, 4 to 20mA current input
2 Terminal 12, reverse operation, 10 to 0V voltage input
3 Terminal C1, reverse operation, 20 to 4mA current input
Only positive values can be input for this feedback
amount of PID control. Negative values (e.g., 0 to -10V, -
10 to 0V) cannot be input, thereby the function cannot be
used for a reverse operation by an analog signal.
Feedback signal setting (H21) must be different from the
type of setpoint value.
