Set "22" (Roll diameter) or "27" (Actual line
speed) 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
22 their setting values are as follows:
26 (Line speed command), 81 (Tension command
after taper compensation), 82 (Winding diameter
compensation torque command), 83 (Inertia
compensation), and 84 (Mechanical loss
compensation).
30: Setting for the Mitsubishi Electric Vector
control dedicated motor SF-V5RU.
10: Terminal 2 input between 0 to 10 V for the line
10
speed with reversible polarity.
Set these parameters according to the motor.

114: Tension control selection (X114) signal ON
(Setting "114" is required for tension control.)
109: Stored winding diameter clear (X109) signal
109
ON (Setting "109" clears the stored roll diameter.)
123: Stall mode trigger signal (X123) signal ON
123
(Setting "123" triggers the stall mode.)
To use the inertia compensation function, assign
111
the Inertia compensation acceleration (X111)
signal and the Inertia compensation deceleration
112
(X112) signal.
To use the inertia compensation function, assign
3
the Line speed acceleration (Y237) signal and the
Line speed deceleration (Y238) signal to affected
output terminals on the inverter for the
4 intermediate roller to output these signal to the
inverter for the winding roller (shaft).
