Dancer feedback speed control details
Purpose
To select forward/reverse action for
PID control
To select winding or unwinding for a
shaft
To select the line speed command
input method
To select a unit of the line speed
To input the line speed command
using multi-speed setting
To calibrate the line speed
command value
To set the line speed command to
start operation
To calibrate the compensation value
added to the line speed command
value
To set acceleration/deceleration
time to increase/decrease the line
speed command value
To detect malposition of the dancer
roll due to a fault such as a break
To enable automatic tuning for
complex PI gain calculation
To enable manual input of gains for
PID control
POINT POINT
• To enable the dancer feedback speed control and the winding diameter compensation function, turn ON the X114 signal and
set "40 or 41" in Pr.128 PID action selection. (When the X114 signal is OFF or "0" is set in Pr.128, the dancer feedback
speed control and the winding diameter compensation function are disabled.)
• Dancer feedback speed control may be performed without using the winding diameter compensation (with the winding
diameter retained) for example for the intermediate shafts. In such cases, turn ON the X114 signal while the X115 signal is
ON or Pr.1247 Winding diameter change increment amount limit = "9999" (no winding diameter calculation).
• For the X114 and X115 signals, assign the function by setting "114 (X114)" or "115 (X115)" in any of Pr.178 to Pr.189 (input
terminal function selection).
