NOTE
• When Pr.128 is set to "0" or the X14 signal is OFF, regular inverter running not dancer control is performed.
• Dancer control is enabled by turning ON/OFF the bits of terminals assigned the X14 signal by RS-485 communication or over
the network.
• When dancer control is selected, set the PID output suspension function (Pr.575 Output interruption detection time =
"9999")
• When Pr.561 PTC thermistor protection level  "9999", terminal 2 cannot be used for the main speed command. Terminal
2 becomes the PTC thermistor input terminal.
Selection of set point/measured value input method (Pr.609, Pr.610)
• Select the set point input method by Pr.609 PID set point/deviation input selection and the measured value input method
by Pr.610 PID measured value input selection. Switch the power voltage/current specifications of terminals 2 and 4 by
Pr.73 Analog input selection or Pr.267 Terminal 4 input selection to match the specification of the input device.
• When Pr.133 PID action set point  "9999", Pr.133 is the set point.
When the set point is set at Pr.133, the setting frequency of Pr.902 is equivalent to 0% and the setting frequency of Pr.903
is equivalent to 100%.


When the same input method 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%)

CC-Link, CC-Link IE Field Network, or LONWORKS communication is available. For details on communication, refer to the Instruction Manual of
each option.
NOTE
• After changing the Pr.73 and Pr.267 settings, check the voltage/current input switch. Incorrect setting may cause a fault,
failure or malfunction. (For the details of the setting, refer to
• 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.
• The following shows the relationship between the input values of the analog input terminals, and the set point and
measured value.
