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.

Motor
Lets the motor rotate at a certain speed and applies a test signal. The
T2-01 =
response to the test signals are analyzed, and adjustments are made
8
to parameters controlling the Feed Forward and KEB Ride-Thru
functions (KEB 2, L2-29 = 1).
T2-01 =
Performs the same operation as Inertia Tuning, but also adjusts the
9
ASR gain according to the response to the test signal.
