5.5.3 Gain adjustment mode 1
You can use this mode when the load inertia (weight) is unknown or the inertia (weight) changes
during machine operation.
The servo drive continually estimates the machine inertia (weight) and updates the value of
P1.037. To reach the expected response, simply adjust the bandwidth response level (P2.031).

5.5.4 Gain adjustment mode 2
When the inertia (weight) cannot be successfully estimated in Gain adjustment mode 1, it is
probably because the machine inertia ratio is greater than 100 times (or the weight is greater
than 200 kg) or the speed and acceleration / deceleration of the actual motor operation are too
low. In this case, you can use Gain adjustment mode 2 to tune the servo system.
In Gain adjustment mode 2, you need to correctly set the machine inertia ratio or total weight in
P1.037 first and then adjust the bandwidth response level (P2.031) to reach the expected
response.
Note: inertia (weight) estimation is available for most machines. However, when the machine does not
comply with the requirements for inertia (weight) estimation, you have to set the correct inertia ratio or total
weight in P1.037.
