• 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 enabled when Pr.128 = "1000 to 2011".

*4 When the same command source has been selected for the set point and measured value at Pr.609 and Pr.610, set point input is invalid. (Inverter
runs at set point 0%)
*5 BACnet MS/TP, CC-Link, CC-Link IE Field Network, or LONWORKS communication is available. For the details of BACnet MS/TP protocol, refer
to page 511. 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. The setting is used when pressure is measured for controlling the flow rate and the following relationship
exists.
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.
