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. 182 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.
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, Pr. 192 or Pr. 197, the terminal output has
negative logic. (For details, refer to section 6.9.5.)
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
RS485 communication, enables dancer control.

(REV) or stop (STOP). Set "16" or "116" in any of
Pr. 190, Pr. 192 or Pr. 197.
