12.2 List of setting items
The items that can be set in the tension control mode are listed below.
You can use the data setter OPX-2A or the
data setting software MEXE02 to set
operation data or change the internal
parameters of the driver.
Parameter codes displayed on the OPX-2A
screen are shown in brackets. These codes are
also referenced in the main text herein. Use
these codes as keywords.
OPX-2A MEXE02
For the method to set parameters with the OPX-2A or MEXE02, refer to the operating manual for each
option.

Reference
Tension command Sets the tension command. The rated torque corresponds to
100%.
tEn

p.111
Material thickness
∗1∗2
Sets the thickness of material. dt
Initial diameter
∗1∗2
Sets the initial diameter when winding or unwinding. din
Final diameter
∗1∗2
Sets the final diameter when winding or unwinding. dPk
p.113
Taper setting
∗1∗2
This function prevents excessively tight winding. As the roll
diameter increases, the tension is lowered. The tension becomes
constant when the taper setting is 100%.
tEP p.114
Core inertial moment
∗2
Sets the inertial moment of the core. Jc
Material inertial moment
∗2
Sets the inertial moment of the material at the maximum material
thickness.
JL
p.114
Speed limit Sets the speed limit value. rEv p.120
∗1 This parameter is set in high function mode I.
∗2 This parameter is set in high function mode II.
