Servo axisescan be switched by pressing the AXIS key when the panel operator in display mode.
5.1.3 Basic Mode Selection
The basic modes include status display mode, parameter setting mode, monitor mode, and utility function mode. Each time the MODE key is pressed, the next mode in the sequence is selected.
Select a basic mode to display the operation status, set parameters and operation references.
The basic mode is selected in the following order
5.1.4 Status Display Mode
The status display mode displays the servo drive status as bit data and codes.
Selecting Status Display Mode
The status display mode is selected when the power supply is turned ON. If it is not displayed, select this mode by pressing MODE key.
Note that the display differs between the speed/torque controland position control types.

5.1.5 Operation in Parameter Setting Mode
The servo drive offers a large number of functions, which can be selected or adjusted by the parameter settings. Refer to A.1 Parameter List for details.
■Parameter Setting Procedures
The parameter settings can be used for changing parameter data. Before changing the data, check the permitted range of the parameter.
The example below shows how to change parameter Pn102 from “100” to “85”.
1． Press MODE key to select the parameter setting mode.
2． Press INC key or DEC key to select parameter number.
3． Press ENTER key to display the current data of Pn102.
4． Press the INC or DEC key to change the data to the desired number 00085. Hold the key to accelerate the changing of value. When the maximum value or minimum value is reached, pressing INC or DEC key respectively, will have no effect.
5． Press the ENTER or MODE key once to return to the display of Pn102.
5.1.6 Operation in Monitor Mode
The monitor mode allows the reference values input into the servo drive, I/O signal status, and servo drive internal status to be monitored.
■Using the Monitor Mode
The example below shows how to display the value (1500) stored in Un001.
1.Press MODE key to select the monitor mode.
2.Press the INC or DEC key to select the monitor number to display
3.Press the ENTER key to display the data for the monitor number selected at step 2
4.Press the ENTER key once more to return to the monitor number display

5.2 Operation in Utility Function Mode
In utility function mode, the panel operator can be used to run and adjust the servo drive and servomotor.
The following table shows the parameters in the utility function mode.
5.2.1 Alarm Traceback Data Display
The alarm traceback display can display up to 10 previously occurred alarms.The alarm is displayed on Fn000, which is stored in the alarm traceback data.
Follow the procedures below to confirm alarms which have been generated.
1. Press the MODE key to select the utility function mode.
2. Press the INC or DEC key to select the function number of alarm traceback data display.
3. Press the ENTER key once, the latest alarm data is displayed.
4.Press the INC or DEC key to display other recent alarms that have occurred.
5. Press the ENTER key, the display will return to Fn000
Note: Hold the ENTER key for one second with alarm code displaying, all the alarm traceback datas will be cleared.
5.2.2 Parameter Settings Initialization
Follow the procedures below to execute the parameter settings initialization.
1.Press the MODE key to select the utility function mode.
2. Press the INC or DEC key to select the function number of parameter settings initialization
3.Press the ENTER key to enter into parameter settings mode.
4.Hold the ENTER key for one second, the parameters will be initialized.
5. Release the ENTER key to ruturn to the utility function mode display Fn001.
Note：
Press the ENTER key during servo ON does not initialize the parameter settings.
Initialize the parameter settings with the servo OFF.
5.2.3 Operation in JOG Mode
Follow the procedures below to operate the servomotor in JOG mode.
1. Press the MODE key to select the utility function mode.
2. Press the INC or DEC key to select the function number of JOG mode operation.
3. Press the ENTER key to enter into JOG operation mode.
4. Press the MODE key to enter into servo ON(servomotor power ON) status.
5. Press the MODE key to switch between the servo ON and servo OFF status.The servo drive must be in servo ON status when the servomotor is running.
6. Press the INC or DEC key to rotate the servomotor.
7. Press the ENTER key to return to utility function mode display Fn002.Now the servo is OFF(servomotor power OFF).
5.2.4 Offset-adjustment of Servomotor Current Detection Signal
Automatic servomotor current detection offset adjustment is performed at ESTUN before shipping. Basically, the user does not need to perform this adjustment.
Perform this adjustment only if highly accurate adjustment is required for reducing torque ripple caused by current offset. This section describes the automatic and manual servomotor current detection offset adjustment.
Note：
·Offset-adjustment of the servomotor current detection signal is possible only while power is supplied to the main circuit power supply and with the servo is the OFF state.
·Execute the automatic offset adjustment if the torque ripple is too big when compared with that of other servo drives.
·If this function, particularly manual adjustment, is executed carelessly, it may worsen the characteristics.
■Automatic Offset-adjustment of Servomotor Current Detection Signal
Adjust the servomotor current detection signal automatically in the following procedure:
1. Press the MODE key to select the utility function mode.
2. Press the INC or DEC key to select the utility function number Fn005.
3. Press the ENTER key to enter into the automatic adjustment of the servomotor current detection signal mode.
4.Press the MODE key,the display will blinks for one second. The offset will be automatically adjusted.
5. Press the ENTER key to return to the utility function mode display Fn005.
Thus, the automatic offset-adjustment of the servomotor current detection signal is complete.
■Manual Offset-adjustment of Servomotor Current Detection Signal
Adjust the servomotor current detection signal manually in the following procedure.
1. Press the MODE key to select the utility function mode.
2. Press the INC or DEC key to select the utility function number Fn006.
3. Press the ENTER key to enter into the manual adjustment of the servomotor current detection signal
4. Press the MODE key to switch between the phase U(o _ CuA) and phase V(1_ Cub) servomotor current detection offset adjustment.
