• 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)

*5 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.
 PID input method according to the operation mode
• The input methods of the set point, measured value, and deviation differ depending on the operation mode as follows.
• Set point input

*1 CC-Link, CC-Link IE TSN, and CC-Link IE Field Network Basic are available.
*2 Input value is "0" when the PLC function is disabled. PID control is disabled when bit 0 of SD1255 is "0".
*3 When Pr.133 ≠ "9999", the Pr.133 setting is used for the set point.
*4 When communication is not specified for the command source in the Network operation mode or when the speed command source is other than
communication, the set point cannot be input via communication. Instead, it can be input via an external terminal (PID control is enabled).
