right side display will show on the LCD display.
2.
Press MODE key to enter into parameter mode.

At this time, the servo drive is ON and the right side display will appear next.
9.
Press DOWN key three times to select the ratio of Load Inertia to Servo Motor
Inertia (J_load /J_motor).
10. Display the current ratio of Load Inertia to Servo Motor Inertia (J_load /J_motor).
(5.0 is default setting.)
11. Press MODE key to select parameter mode.
12. Press SHIFT key twice to select parameter group.
13. Press UP key to select user parameter P4-05.
14. Press SET key and JOG speed 20rpm will be displayed. Press UP and DOWN

16. Pressing UP key is forward rotation and pressing DOWN key is reverse rotation.
17. Execute JOG operation in low speed first. After the machine is running smoothly, then execute JOG
operation in high speed.
18. The ratio of Load Inertia to Servo Motor Inertia (J_load /J_motor) cannot be shown in the display of
JOG parameter P4-05 operation. Please press MODE key twice continuously, and the user can see
the ratio of Load Inertia to Servo Motor Inertia (J_load /J_motor). Then, execute JOG operation again,
press MODE key once and press SET key twice to view the display on the keypad. Check if the value
of J_load /J_motor is adjusted to a fixed value and displayed on the keypad after acceleration and
deceleration repeatedly.
