Note:
●Jog test running is recommended firstly before gain adjustment to ensure motor runs normally.
●Servo gain can be set by combination of multi-parameter (position-loop, speed-loop, filter,
load rotational inertia ratio etc.), these parameters interact on each other. Therefore, balance of
parameters must be considered.

9.2 Inertia Identification

When motor is connected to machine or load simulator, before normal production, servo drive
must "study" the rotational inertia of machine, which is convenient for user to adjust related
parameters and make sure servo system run in proper inertia.
Inertia ratio=Total load inertia of machine/Motor rotor inertia
