4. Panel Operator

4.1 Basic Operation

4.1.1 Functions on Panel Operator

The panel operator is a built-in operator that consists of display section and keys located on the front
panel of the servo drive.
Parameter setting, status display ,and execution of utility function are enabled using the panel operator. 
The names and functions of the keys on the panel operator are shown as follows:

4.1.2 Axis Switching
Since the Servodrive only can set and monitor only one axis at a time, the use can press the [AXIS] key to switch the control into another axis. The indicator lamp behind each axis can show the work status:
 Lit indicates the axis is controlled at present.
 Not lit indicates the axis is not controlled at present.
 Blinking indicates an alarm occurred in the axis not controlled at present.

4.1.3 Mode Switching
As is shown in the following figure, press [M] key can switch the mode among Status Display, Parameter Setting, Monitor and Utility Function in turns. 

 

4.2 Status Display

The status display mode displays the servo drive status as bit data and codes.
The status display mode is selected when the power supply is turned ON. If it is not displayed, select this mode by pressing [M] key.
Note that the display differs between the speed/torque control and position control.

The following table lists the description of each bit data in speed/torque control and position control. 

The following table lists the description of code. 

 

4.3 Operation in Parameter Setting Mode

The servo drive offers a large number of functions, which can be selected or adjusted by the parameter settings. For details about each parameters description see the section Appendix A Parameters List.
The following procedure is an example for changing the setting of parameter Pn102 from 100 to 85.
Step 1 Press [M] key for several times to switch into Parameter Setting mode, after turning the Servodrive ON.

Step 2 Press [▲] key or [▼] key to select the parameter Pn102.

Note: press and hold [▲] key or [▼] key to jump the parameter number quickly.
Step 3 Press [◄] key to display the current value of Pn102. 

Step 4 Press [▼] key or [▼] key to change the value to 00085. Press and hold [▼] key or [▼] key to jump the setting value quickly.

Step 5 Press [◄] key or [M] key to return to the display of the current parameter.

Initialize the parameter settings of axis-A

Initialize the parameter settings of axis-B

 

Initialize the parameter settings of axis-C

Step 4 Press and hold [◄] key for 1 second or more until “done” is displayed and blinked, which indicates the parameter settings initialization has been completed. 

 

Step 5 Relase [◄] key to return to the display of the current function number

----End

 

4.5.3 JOG Operation
Follow the procedures below to operate the Servomotor in JOG.
Step 1 Press [M] key for several times to switch into Utility Function mode, after turning the servo ON.
Step 2 Press [▲] key or [▼] key to select the function number Fn002.

Step 3 Press [◄] key to enter the JOG running mode.

Step 4 Press [M] key to turn ON the servo.
