n Inertia Tuning and Speed Control Loop Auto-Tuning
Inertia Tuning can be performed when the drive is using CLV control for either IM or PM motors. Inertia Tuning automatically
calculates load and motor inertia, and optimizes settings related to the KEB Ride-Thru function (KEB 2) and Feed Forward
control.
ASR Gain Auto-Tuning performs the same operation as Inertia Tuning, while also optimizing speed control loop settings.

Table 4.19 Inertia and Speed Control Loop Tuning
Setting
Allows the motor to rotate at a certain speed and applies a test signal.
The response to the test signal is analyzed and the necessary
adjustments are made to parameters controlling the Feed Forward and
KEB Ride-Thru functions (KEB 2, L2-29 = 1).
Performs the same operation as Inertia Tuning, while also adjusting
the ASR gain according to the test signal response.
