Dancer control detail
3.7.2
Dancer roll target position (Pr. 133, Pr. 702, Pr. 731)
(1) Dancer signal input selection
(Pr. 731)
Use
Pr. 731
to assign a terminal for the dancer signal input.
(2) PID set point
(Pr. 133)
Set the desired set point (%) with parameter.
Set the target position of dancer roll (center position) in
Pr. 133
.
If position signal from dancer roll to the terminal 1 is 10V at the upper limit position, -10V at the lower limit position, and 0V
at the center position (target position), set 500% in
Pr. 133
.
If -5V at the center (target position), set 450% to
Pr. 133
.
-10V to 10V of voltage can be input to terminal 1.
Y54 signal is ON when dancer roll, which is viewed from the target position, is within the range set in
Pr. 702
.
(3) Dancer roll position detection
(Pr. 702)
Dancer roll position detection signal Y54 is output when dancer roll, which is viewed from the target position, is within the
range set in
Pr. 702
. Set "54 (positive logic) or 154 (negative logic)" in any of
Pr. 190 to Pr. 196 (Output terminal function
selection)
to assign Y54 signal to an output terminal.

REMARKS
• Dancer position can be monitored in % by setting
Pr. 52
= "27".
• The automatic restart after instantaneous power failure function is disabled when the dancer control is valid (
Pr. 128
= "40, 41").
