5.4.2 Tuning mode 1
In this mode, the servo drive continues to estimate the machine inertia and updates the value of
parameter P1.037.

Requirements for inertia estimation:
1. Motor speed increases from 0 rpm to 3000 rpm within 1.5 seconds.
2. It is suggested to set the speed to 500 rpm or higher. The lowest speed should be no less
than 200 rpm.
3. The load inertia should be less than 50 times the motor inertia.
4. The change in the external force or inertia ratio cannot be too great.
5.4.3 Tuning mode 2
When Tuning mode 1 cannot meet your need, you can try Tuning mode 2 to tune the servo
system. In Tuning mode 2, the system does not automatically estimate the inertia. You must set
the correct mechanical inertia in parameter P1.037.

Inertia estimation is applicable to most applications. However, when the machine does not
comply with the requirements for inertia estimation, you have to set the correct inertia ratio in
parameter P1.037.
