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).
71 Applied motor 0 30
30: Setting for the Mitsubishi Electric Vector control dedicated
motor SF-V5RU.
72 PWM frequency selection 2 15
73 Analog input selection 1 10
10: Terminal 2 input between 0 to 10 V for the line speed and
terminal 1 input between 0 to 10 V for the dancer signal with
reversible polarity.
80 Motor capacity 9999 15 kW
Set these parameters according to the motor.
81 Number of motor poles 9999 4 (poles)
83 Rated motor voltage 200 V 164 V
84 Rated motor frequency 9999 51
128 PID action selection 0 40 40: Dancer control enabled (reverse action)

PID proportional band 100% 100%
Performing tension PI gain tuning allows setting these
parameters.

PID action set point 500% 550%
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.

∗1
PID differential time 9999 9999
To improve trackability of a mechanical extraneous disturbance
(variation), set 0.01 seconds at first, and change the setting to a
slightly larger value as required. (Set the minimum possible
value because setting a too large value causes hunting.)
158 AM terminal function selection 1 19 19: Analog output signal for dancer tension control
180 RL terminal function selection 0 114
114: Tension control selection (X114) signal ON (Setting "114" is
required for tension control.)
181 RM terminal function selection 1 109
109: Stored winding diameter clear (X109) signal ON (Setting
"109" clears the stored roll diameter.)
186 CS terminal function selection 6 7
7: External thermal relay input (OH) signal (Setting "7" is required
for signals input from the SF-V5RU thermal protector.)
190 RUN terminal function selection 0 232
232: Winding diameter calculation completion at start (Y232)
signal (positive logic)
267 Terminal 4 input selection 0 2 2: Terminal 4 input between 0 to 10 V for the taper ratio setting

If setting Pr.361 to "8", set a line speed command value in this
parameter.
