Special operation and frequency control
(4) 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
(
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.

NOTE
Changing the terminal function using any of
Pr. 178 to Pr. 182, Pr. 190, Pr. 192, and Pr. 197
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. (
for setting)
Turn OFF PID output suspension function (
Pr. 575
= "9999") while using dancer control.
When
Pr. 561 PTC thermistor protection level
≠
"9999", terminal 2 is not available for main speed command. Terminal 2 is
used as PTC thermistor input terminal.
