(A) Application parameters
● 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)

Tab. 5-170: Relationship between the signals
Can be changed by Pr. 73 and Pr. 267 and the voltage/current input switch. (Refer to page 5-255.)
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.
