ASDA-A2 Chapter 5 Trial Run and Tuning ProcedureRevision September 2012 5-135.6 Tuning ProcedureTable 5.A Estimate the ratio of Load Inertia to Servo Motor Inertia (J_load /J_motor): JOG ModeTuning Procedure Display1. After wiring is completed, when power in connected to the AC servodrive, the right side display will show on the LCD display.2. Press MODE key to enter into parameter mode.3. Press SHIFT key twice to select parameter group.4. Press UP key to view each parameter and select parameter P2-17.5. Press SET key to display the parameter value as shown on the right side.6. Press SHIFT key twice to change the parameter values. Use UP key tocycle through the available settings and then press SET key to determinethe parameter settings.7. Press UP key to view each parameter and select parameter P2-30.8. Press SET key to display the parameter value as shown on the right side.9. Select parameter value 1. Use UP key to cycle through the availablesettings.10. At this time, the servo drive is ON and the right side display will appearnext.11. Press DOWN key three times to select the ratio of Load Inertia to ServoMotor Inertia (J_load /J_motor).12. Display the current ratio of Load Inertia to Servo Motor Inertia (J_load/J_motor). (5.0 is default setting.)13. Press MODE key to select parameter mode.14. Press SHIFT key twice to select parameter group.15. Press UP key to select user parameter P4-05.16. Press SET key and JOG speed 20 r/min will be displayed. Press UP andDOWN key to increase and decrease JOG speed. To press SHIFT key onetime can add one digit number.17. Select desired JOG speed, press SET key and it will show the right sidedisplay.18. Pressing UP key is forward rotation and pressing DOWN key is reverse rotation.19. Execute JOG operation in low speed first. After the machine is running smoothly, thenexecute JOG operation in high speed.20. The ratio of Load Inertia to Servo Motor Inertia (J_load /J_motor) cannot be shown in thedisplay of JOG parameter P4-05 operation. Please press MODE key twice continuously andthe users 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 thedisplay on the keypad. Check if the value of J_load /J_motor is adjusted to a fixed valueand displayed on the keypad after acceleration and deceleration repeatedly.
