GE AF-300 P11 User Manual page 91

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.
