Revision February, 2017                                                                      5-11 
5.6 Tuning Procedure 
Estimate the inertia ratio: JOG Mode 
Tuning Procedure 
Display 
1.  After completing wiring, when applying to the power, the servo drive will 
display: 
 
2.  Press the MODE Key to select the mode of parameter function. 
 
3.  Press the SHIFT Key twice to select the mode of parameter group. 
 
4.  Press the UP Key to select parameter P2-17. 
 
5.  Press the SET Key to display parameter value, which is shown as the 
content on the right. 
 
6.  Press the SHIFT Key twice, then press the UP Key and then press the 
SET Key. 
 
7.  Press the UP Key to select parameter P2-30. 
 
8.  Press the SET Key to display the parameter value. 
 
9.  Press the UP Key and select the parameter value 1. 
 
10.  Then, the servo drive is ON and will show: 
 
11.  Press the MODE Key and then press the DOWN Key to select the value of 
inertia ratio. 
 
12.  The panel displays the current value of inertia ratio / total weight of 
movable section and load (kg) (default value). 
 
13.  Press the MODE Key to select the mode of parameter function. 
 
14.  Press the SHIFT Key twice to select the mode of parameter group. 
 
15.  Press the UP Key twice to select parameter P4-05. 
 
16.  Press the SET Key to show the content, which is 20r/min at JOG speed. 
Press the UP or DOWN Key to increase or decrease the JOG speed. 
Press the SHIFT Key to move to the next digit of the left. 
 
17.  Set the desired JOG speed and press the SET Key which is shown as the 
figure on the right. 
 
18.  Press the UP Key to rotate the motor in forward direction while press the DOWN Key the 
motor will rotate in reverse direction.  
19.  Execute JOG operation at low speed first. With the constant speed, if the motor operates 
smoothly in forward and reverse direction, users can execute JOG operation at higher speed. 
20.  In P4-05, the servo drive cannot display inertia ratio. Please press the MODE Key twice to 
view the value of inertia ratio. If users desire to execute JOG operation again, press the 
MODE Key, and then press the SET Key twice. Observe the panel display to see if the load 
inertia ratio / total weight of movable section and load remain at the same value after 
acceleration and deceleration.
