(1) Not required for the Logix Designer application, version 29.00 and later.
(2) If it is not desired to rotate the motor (due to coupled load) you can perform this test for induction motor closed-loop mode and skip the Dynamic test. The dynamic test
provides the best results for induction motor closed-loop mode.
(3) The motor inertia value must be non-zero prior to running a dynamic test. The motor inertia value is estimated automatically based upon the Motor Nameplate data in
the Logix Designer application, version 29.00 and later. For previous versions, an Autotune test must be run or the motor inertia value entered directly.

Motor>Analyzer Category
From the Motor>Analyzer category you can perform three types of tests to
identify motor parameters.
In this example, the Calculate Model test was run. If the Motor>Analyzer test
executes successfully, and you accept the test values, they populate the Model
Parameter attributes.

Motor Tests and Autotune Procedure

You can perform three types of tests to identify motor parameters and one test
for motor/system inertia. These parameters are used by sensorless-vector
frequency-control and induction motor closed-loop modes.
recommends which test to use based on the control mode and application.
