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
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).
71 Applied motor 0 30
30: Setting for the Mitsubishi Electric Vector
control dedicated motor SF-V5RU.
73 Analog input selection 1 1 10
10: Terminal 2 input between 0 to 10 V for the line
speed with reversible polarity.
80 Motor capacity 9999 7.5 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 Hz

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 1 109
109: Stored winding diameter clear (X109) signal
ON (Setting "109" clears the stored roll diameter.)
182 RH terminal function selection 2 2 123
123: Stall mode trigger signal (X123) signal ON
(Setting "123" triggers the stall mode.)
184 AU terminal function selection 4 4 111
To use the inertia compensation function, assign
the Inertia compensation acceleration (X111)
signal and the Inertia compensation deceleration
(X112) signal.
189 RES terminal function selection 62 62 112
193 OL terminal function selection 3 237 3
To use the inertia compensation function, assign
the Line speed acceleration (Y237) signal and the
Line speed deceleration (Y238) signal to affected
output terminals on the inverter for the
intermediate roller to output these signal to the
inverter for the winding roller (shaft).
