9.2 List of setting items
The items that can be set in the position 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
Gain tuning mode selection Selects the gain tuning mode. [APP-0-00]
Load inertial moment ratio Sets the ratio of load inertial moment and motor inertial moment [APP-0-01]
Mechanical rigidity setting Selects the rigidity applicable to automatic, semi-auto or manual
tuning.
[APP-0-02]
Position loop gain Sets the position loop gain. When this value is increased, the
response will increase.
[APP-0-03]
Speed loop gain Sets the speed loop gain. When this value is increased, the
response will increase.
[APP-0-04]
Speed loop integral time
constant
Sets the speed loop integral time constant. When this value is
decreased, the response will increase.
[APP-0-05]
Speed feed-forward rate Sets the speed feed-forward rate. This parameter can be used to
shorten the positioning time.

automatic offset
Changes the setting to enable/disable automatic offset for analog
input signals.
[APP-2-06]
p.60
Analog speed monitor
maximum value
Sets the maximum value of monitored analog speed. This setting
determines the slope of output of monitored analog speed.
[APP-2-07]
Analog speed monitor
maximum voltage
Sets the monitored output voltage corresponding to the
maximum value of monitored analog speed.
[APP-2-08]
Analog speed monitor
offset voltage
Sets the offset voltage for monitored analog speed.
