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.

Auto-Tuning Interruption and Fault Codes

If tuning results are abnormal or the STOP key is pressed before completion, Auto-Tuning will be interrupted and a fault code
will appear on the digital operator.

Application Conditions and Benefits
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.
