function
Control mode Set the control mode. Available Available
Tension control mode Select the tension control mode.
Simple: The tension is controlled at a constant level when the feed rate is
constant during winding operation, etc.
High function I: The current winding (unwinding) diameter is calculated
automatically based on the initial diameter, material thickness and final
diameter. The tension is controlled at a constant level regardless of the
operating speed.
High function II: In addition to the control in high function mode I, the load
inertial moment is calculated internally by the driver based on the material
inertial moment and core inertial moment. The tension is controlled at a
constant level even during acceleration/deceleration.

Material inertial
moment
Set the inertial moment corresponding to the maximum material diameter in
high function mode I or high function mode II.
Not

Available
Taper setting Reduce the tension according to the change in the roll diameter to prevent
excessively tight winding, in high function mode II.

Analog/digital selection Toggle operation data No. 0 and No. 1 between analog setting and digital
setting. When this parameter is set to “Enable,” operation data Nos. 0 and 1
become analog settings, while Nos. 2 to 7 provide digital settings. When the
parameter is set to “Disable,” all operation data numbers provide digital
