Setting Dancer Control
• PID Control PID Command via Communication (3002Hex-0EHex)
When “4: EtherCAT communication” is selected, the reference position during dancer control is set
in the range of -100% to 100% to PID Control PID Command via Communication (3002Hex-0EHex).
•
PID Control (Dancer control gain switching) (300EHex-3BHex to 300EHex-3EHex)
When the position of the dancer roll (feedback) enters the “Dancer position set point ± PID Control
PID Reference Position Detection Width for Dancer (300EHex-3BHex),” the PID constant of the PID
controller is switched from 300EHex-04Hex, 300EHex-05Hex and 300EHex-06Hex to
300EHex-3CHex, 300EHex-3DHex and 300EHex-3EHex. It is possible to increase the gain and
thus improve the responsiveness, and increase the accuracy.
PID Control PID Reference Position Detection Width for Dancer (300EHex-3BHex)
Set in the range of 1% to 100%. If set to 0, switching of the PID constant is not performed.
PID Control P Gain 2 (300EHex-3CHex)
PID Control I Integral Time 2 (300EHex-3DHex)
PID Control D Differential Time 2 (300EHex-3EHex)
Same as PID Control P Proportional Gain (300EHex-04Hex), PID Control I Integral Time
(300EHex-05Hex) and PID Control D Dif
ferential T
ime (300EHex-06Hex).
• PID Control Block Selection (300EHex-3FHex)
It is possible to select whether to add or subtract the output of the PID controller of dancer control to
or from the main settings. It is also possible to select whether to perform control of the main settings
by the output of the PID controller based on the ratio, or to perform correction based on the absolute
value (Hz).

Terminal Input Function
• PID control cancellation “PID” (20: PID enabled/disabled)
When “PID enabled/disabled (20: PID)” is ON, switching occurs from PID control to manual frequen-
cy setting.
Input signal “PID” Function selected
OFF PID control enabled
ON PID control disabled (manual frequency setting)
“PID (20: PID enabled/disabled)” OFF -> ON operation
If, during PID operation, the PID terminal is switched from OFF to ON and set to the PID canceled
state, and Frequency Reference Selection (3004Hex-02Hex/3006Hex-1FHex) is set to “7: UP/
