PID control detects the amount of control (feedback
amount) from a sensor of the control target, then
compares it with the target value (e.g., reference
temperature). If the values differ, this function performs a
control to eliminate the deviation. In other words, this
control matches the feedback amount with the target
value.
This function can be used for flow control, pressure control,
temperature control, and other process controls.

Feedback amount
Forward or reverse operations can be selected for PID
controller output. This enables motor revolutions to be
faster or lower according to PID controller output
This function cannot be used when the motor 2 is
selected.

The target value can be entered using F01, "Frequency
setting 1," or directly from the keypad panel. Select any
terminal of Terminals X1 (E01) to X9 (E09) and set value
11 (frequency setting switching).
For entry from F01, "Frequency setting 1," input an OFF
signal to the selected terminal. For direct entry from the
keypad panel, turn on the selected terminal.
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
coefficient B."
This function selects the feedback amount input terminal
and electrical specifications of the terminal. Select a value
from the table below according to sensor specifications.

0 Control terminal 12, forward operation (0 to
10V voltage input)
1 Control terminal C1, forward operation (4 to
20mA current input)
2 Control terminal 12, reverse operation (10
to 0V voltage input)
3 Control terminal C1, reverse operation (20
to 4mA current input)

Feedback amount
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.
