6.5.2
Winding/unwinding shaft selection
Select whether the target roll is a winding shaft or unwinding shaft.
Winding/unwinding selection (Pr.1230)
• Use
Pr.1230 Winding/unwinding selection
to select whether the target roll is a winding shaft or unwinding shaft.
• The initial diameter of the winding shaft is selected according to whether the operation is winding or unwinding.
6.5.3
Tension feedback setting
Set parameters for tension feedback.
Select the input interface (analog input terminal) used for inputting tension feedback to the inverter.
∗1
The setting range varies depending on the
Pr.1401
setting.
PID set point
• Use a commanded tension value after taper compensation to set the set point for tension feedback. Select the tension
command input method in
Pr.804 Tension / Torque command source selection
.
NOTE
• Refer to
Pr.804
for the taper function.
Tension feedback input selection (Pr.363)
• Use
Pr.363 Dancer / tension sensor feedback input selection
to select the input terminal for tension feedback.
