7. Enable drive
8. Start Inertia autotuning. When either of these two buttons is pressed the inertia auto tune starts. The
motor moves as configured in the previous screen. The calculated inertia value appears in the
"estimated moment of inertia" box. Continue with the test until this value is stable.
9. Disable the drive
10. Save the inertia value in the parameter H08-15
6.6.1.1 ONLINE AUTO-TUNING
This method automatically calculates the inertia from the movements sent by the host controller. The servo
drive calculates the inertia ratio in real time and stores the result to H08-15 every 30 minutes
Different H09-03h values indicating different updating speeds of the inertia ratio in H08-15
• H09-03h = 1: Applicable to the scenario where the actual inertia ratio rarely changes, such as machine
tool and wood carving machine.
• H09-03h = 2: Applicable to the scenario where the inertia ratio changes slowly.
• H09-03h = 3: Applicable to the scenario where the actual inertia ratio changes rapidly, such as
transportation manipulator.
NOTE Do not use online inertia auto-tuning in applications involving hitting against limit switches and press
fitting.
