Para. No. Name Description
H08-31
Disturbance
observation cutoff
frequency
The higher the cutoff frequency is, the more easily will the vibration occur.
H08-32
Disturbance
observation
compensation
coefficient
Defines the compensation percentage for observation.
H08-33
Disturbance
observation
inertia correction
coefficient
Set this parameter only if the set inertia does not fit the actual conditions. The
acting inertia is the result of multiplying the value of H08-33 by the set inertia. It is
recommended to use the default value of H08-33.

6.5.7 Speed observer
The speed observer is intended to be used in applications with small load/inertia changes. It facilitates
quick positioning through improving the responsiveness and filtering high frequencies.
The block diagram for the speed observer is as follows.
