Special operation
I/O signals and parameter setting
Set "40 to 43" in Pr. 128 to perform dancer control.
Set "14" in any of Pr. 178 to Pr. 184 "Input terminal function selection" to assign PID control
selection signal (X14) to turn the X14 signal on.
When the X14 signal is not assigned, only the Pr. 128 setting makes dancer control valid.
Input the set point using Pr. 133, then input the measured value signal (dancer roller position
detection signal) across terminal 4 and 5 of the inverter.
NOTES
When Pr. 128 = "0" or X14 signal is off, normal inverter operation is performed without dancer
control.
Turning ON/OFF of bit of the terminal, to which X14 signal is assigned through network as RS-485
communication, enables dancer control.

Tab. 6-116: I/O signals and parameter setting
When the X14 signal is not assigned, only the Pr. 128 setting makes dancer control valid.
The half-tone screened areas indicate the parameter initial values.
When 100 or larger value is set in any of Pr. 190 to Pr. 192 "Output terminal function selection", the
terminal output has negative logic. (For details, refer to section 6.10.5.)
NOTES
Changing the terminal function using any of Pr. 178 to Pr. 184 and Pr. 190 to Pr. 192 may affect the
other functions. Make setting after confirming the function of each terminal.
When the Pr. 267 setting was changed, check the voltage/current input switch setting. Different
setting may cause a fault, failure or malfunction. (Refer to page 6-178 for setting.)

Description
Turn on X14 signal to perform
dancer control.
Input the signal from the dancer
roller detector (measured value sig-
nal).
4–20 mA ........0–100%
0–5 V ...............0–100%
0–10 V.............0–100%
Output to indicate that the meas-
ured value signal exceeded the
maximum value (Pr. 131).
Output when the measured value
signal falls below the minimum
value (Pr. 132).
Output is "ON" when the output
indication of the parameter unit is
forward rotation (FWD) and "OFF"
when reverse rotation (REV) or stop
(STOP).
Turns on during PID control.
Common terminal for open collec-
tor output terminal.
