PARAMETERS
 When Pr.133  "9999", the Pr.133 setting is valid.
 For the details of CC-Link communication, refer to the Instruction Manual of the option FR-A8NC, FR-A8NCE.
 For the details of the PLC function, refer to the PLC Function Programming Manual.
• The set point/deviation input method can also be flexibly selected by Pr.609 PID set point/deviation input selection and
the measured value input method can be selected by Pr.610 PID measured value input selection. Selection by Pr.609
and Pr.610 is valid when Pr.128 = "1000 to 2011".
 When the same input method has been selected for the set point and measured value using Pr.609 and Pr.610, set point input is invalid. (The
inverter runs at set point 0%)
NOTE
• When terminals 2 and 4 are selected for deviation input, perform bias calibration using C3 and C6 to prevent a minus voltage
from being entered as the deviation input signal. Input of a minus voltage might damage devices and the inverter.
• 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)
 Can be changed by Pr.73 and Pr.267 and the voltage/current input switch. (Refer to page 406.)
NOTE
• Always perform calibration after changing the voltage/input specification with Pr.73, Pr.267, and the voltage/current input
selection switch.
