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 4.32 Inertia and Speed Control Loop Tuning
Type Setting Control Mode Application Conditions and Benefits
Inertia Tuning
IM
Motor
T1-01 = 8 CLV 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). PM
Motor
T2-01 = 8 CLV/PM
ASR Gain Auto-
Tuning
IM
Motor
T1-01 = 9 CLV
Performs the same operation as Inertia Tuning, while also adjusting the ASR gain
according to the test signal response. PM
Motor
T2-01 = 9 CLV/PM
Note: Inertia Tuning and ASR Gain Auto-Tuning may not be available when gears are between the machine and the motor shaft.
Table 4.33 explains the data that must be entered to perform the Inertia Tuning and ASR Gain Auto-Tuning. Refer to Auto-
Tuning for Permanent Magnet Motors on page 188 for details.

u 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.
