• 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 Inspect
terminal specification
Terminal 2 0 to 5 V
0 to 10 V
0 to 20 mA
Terminal 1 0 to ±5 V
0 to ±10 V
Terminal 4 0 to 5 V
0 to 10 V
0 to 20 mA
*6 Can be changed by Pr.73 and Pr.267 and the voltage/current input switch. (Refer to
NOTE
• Always perform calibration after changing the voltage/input specification with Pr.73, 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.
