Inertia Tuning and Speed Control Loop Auto-Tuning
Inertia Tuning can be performed when the drive is using Closed Loop Vector 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, but also optimizes speed control loop settings.

Application Conditions and Benefits
• Motor does not rotate during Auto-Tuning
T2-01 = 0
• Motor test report or motor data like listed in
• A motor test report listing motor data is not available. Drive
T2-01 = 1
automatically calculates and sets motor parameters.
• Useful to tune the drive when the motor data were set up manually or by
T2-01 = 2
motor code and the cable is longer than 50 m. Should also be performed if
the cable has changed after earlier tuning.
• PG encoder has been replaced. Calculates the Z pulse offset.
T2-01 = 3
• Requires the motor to rotate with no or very low load.

PM Motor
Lets the motor rotate at a certain speed and applies a test signal. The response to the test
T2-01 = 8
signals are analyzed, and 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, but also adjusts the ASR gain according
T2-01 = 9
to the response to the test signal.
