Set "22" (Roll diameter) for monitoring.
Or use any of Pr.774 to Pr.776 when using the 3-line monitor
screen on the PU.
Other monitor items related to this application and their setting

values are as follows:
26 (Line speed command), 27 (Actual line speed), 28 (Dancer
compensation speed), 29 (Winding length), 52 (PID set point), 53
(PID measured value), and 54 (PID deviation).

1 10 terminal 1 input between 0 to 10 V for the dancer signal with
reversible polarity.

Set Pr.52 = "86" (Terminal 1 input after calibration in %) to check
the upper and lower limit of the dancer roll position. Set the target

position (neutral position) in this parameter according to the
check result.
To improve trackability of a mechanical extraneous disturbance
(variation), set 0.01 seconds at first, and change the setting to a
9999 9999
slightly larger value as required. (Set the minimum possible
value because setting a too large value causes hunting.)
1 19 19: Analog output signal for dancer tension control
114: Tension control selection (X114) signal ON (Setting "114" is
0 114
required for tension control.)
109: Stored winding diameter clear (X109) signal ON (Setting
1 109
"109" clears the stored roll diameter.)
