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 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.
REMARKS
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.

The shaded area indicates the parameter initial value.

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 page 145)
NOTE
Changing the terminal function using any of Pr. 178 to Pr. 184 and Pr.190 to Pr.192 may affect the other functions. Set
parameters 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 176 for setting)
