Parameter Settings during Inertia and Speed Control Loop Auto-Tuning: T3
These tuning methods apply a sine wave test signal to the system. The drive estimates the system inertia by the measuring the
response and automatically sets the parameters listed in

T3-01: Inertia Tuning Frequency Reference
Sets the frequency of the test signal applied to the motor during Inertia Tuning. Although this setting rarely needs to be changed,
increasing the value may be beneficial when working with high inertia loads.

T3-02: Inertia Tuning Reference Amplitude
Enter the amplitude of the test signal applied to the motor during Inertia Tuning. Although this setting rarely needs to be
changed, decrease the setting if a large load inertia causes problems during Inertia Tuning. Adjust T3-02 if a fault occurs when
T3-01 is set to a low value.

T3-03: Motor Inertia
Enter the inertia of the motor. This value is used to determine the load inertia using the test signal response. The default setting
is for a Yaskawa standard motor as listed in the motor inertia table.
