*2 BACnet MS/TP, CC-Link, CC-Link IE Field Network, or LONWORKS communication is available. For details on BACnet MS/TP protocol, refer to
page 516. For details of other types of communication, refer to the Instruction Manual of each option.
*3 For details on 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".

*4 When the same command source 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%)

page 516. For details of other types of communication, refer to the Instruction Manual of each option.
• When Pr.610 PID measured value input selection = "101 to 105", the square root of the input value is used as the
measured value.
NOTE
• When terminals 2 and 4 are selected for deviation input, perform bias calibration using Pr.902 and Pr.904 to prevent a
minus voltage from being entered as the deviation input signal. Input of a minus voltage might damage devices and the
inverter.
