Set "40 to 43" in [Pr. 128 ] to perform dancer control.
(Disable PID output interruption function ([ Pr. 575 =
9999]) during 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 main speed command (External, PU,
Network). The main speed command in any
operation mode can be input. (Note that terminal 4
can not be used as the main speed command.)

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 [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.
