2.3 Monitored items

Detected speed
You can check the speed of the motor (unit: r/min).
While the motor is rotating in the CCW direction, “−” is shown in front of the displayed value. If the
speed is indicated by an absolute value, no sign is shown to indicate the rotating direction. You can select
the value display format using the displayed speed on OPX-2 parameter [APP-5-02] (p.35).
You can also display the motor speed as revolutions of the gear output shaft. For this setting, use the
deceleration rate of speed monitor parameter [APP-4-05] (p.35).

Command position
You can check the current position of the motor with reference to the home position.
If a resolution is set, an appropriate value based on the resolution is shown as steps.

Detected torque
You can check the generated motor torque.
The generated torque is indicated as a percentage of the rated torque being 100%.

Estimate inertial moment ratio
You can check the load inertial moment ratio estimated internally by the driver.
The estimate inertial moment ratio indicates the percentage of the load inertial moment to the rotor
inertial moment of the motor. If the rotor inertial moment is the same as the load inertial moment,
“100%” is shown.

Operation number
You can check the operation data number corresponding to the data used in the current operation.

Present alarm
When an alarm generates, a corresponding alarm code will be displayed.
You can also reset alarms or check and clear alarm records.
Note Do not turn off the driver power while an alarm is being reset or alarm records are
being cleared (= while the display is blinking). Doing so may damage the data.
• How to reset an alarm
1. While an alarm is displayed, press the key to move to the lower level.
2. Press the key twice to select the alarm reset screen.
3. Press the key.
The alarm is reset.
Note Some alarms cannot be reset on the OPX-2A. For details, refer to “Alarm code list” on
p.20. To reset these alarms, you must cycle the power.
