Mitsubishi Electric FR-F820-00046 Instruction Manual page 409

• The following shows the relationship between the input values of the analog input terminals and set point, measured value
and deviation. (Calibration parameter initial values)
Input terminal
Terminal 2
Terminal 1
Terminal 4
*6 Can be changed by Pr.73 Analog input selection, Pr.267 Terminal 4 input selection and the voltage/current input switch. (Refer to
NOTE
• Always calibrate the input after changing the voltage/current input specification with Pr.73 and Pr.267, and the voltage/current
input selection switch.
 Multistage set point input (Pr.1460 to Pr.1466)
• The set point can be selected by combining the ON/OFF status of the PDI1 to PDI3 signals. Up to eight set points can be
selected. Use Pr.1460 PID multistage set point 1 to Pr.1466 PID multistage set point 7 to set the target values for
selection.
• When "9999" is set in the selected multistage set point parameter, PID control is performed according to the Pr.128,
Pr.609, and Pr.133 settings.
Selected set point

Multistage set point 1
Multistage set point 2
Multistage set point 3
Multistage set point 4
Multistage set point 5
Multistage set point 6
Multistage set point 7
*1 When functions are not assigned to the input terminals, the signals are treated as OFF.
NOTE
• The multistage set point input is not available for the second PID.
• The priority of the set point input is as follows: Pr.1460 to Pr.1466> Pr.133> Pr.128.
 Input/output signals
• Assigning the PID control valid (X14) signal to the input terminal by Pr.178 to Pr.189 (Input terminal function selection)
enables PID control to be performed only when the X14 signal is turned ON. When the X14 signal is OFF, regular inverter
running is performed without PID action . (When the X14 signal is not assigned, PID control is enabled only by setting
Pr.128 ≠ "0".)
