6.1.4 Torque disturbance observation
Disturbance observer can reduce the influence of external disturbance on servo system and improve the
anti-disturbance ability by detecting and estimating the external disturbance torque of the system and
compensating the torque command.
If the soft mode is selected in the auto-tuning mode, the disturbance observer will be closed
automatically, and the gain of the disturbance observer will not change. If the fast positioning or fast
positioning (control overshoot) is selected, the disturbance observer will be opened automatically, and
the gain of the disturbance observer will be modified to 85. The relevant parameters of this function no
need to be set manually by users.

6.2 Rotary inertia presumption
6.2.1 Overview
Rotational inertia estimation is the function of automatic operation (forward and reverse) in the driver
and estimate the load inertia in operation.
Rotational inertia ratio (the ratio of load inertia to motor rotor inertia) is a benchmark parameter for
gain adjustment, and it must be set to the correct value as far as possible.

6.2.2 Notes
Occasions where inertia cannot be presumed
➢ Mechanical systems can only operate in one direction
The occasion where inertia presumption is easy to fail
➢ Excessive load moment of inertia
➢ The running range is narrow and the travel is less than 0.5 circles.
➢ The moment of inertia varies greatly during operation.
➢ Mechanical rigidity is low and vibration occurs when inertia is presumed.
