If I understand your question correctly, you are asking about a static autotune of a drive, correct?

Assuming that:
A static autotune (where the motor does not rotate) allows the drive to determine the electrical characteristics of the motor's windings, as well as the properties of the wiring between drive and motor. The drive "pings" the motor and determines parameters such as as line resistance, inductance, etc... This allows the drive to develop an "electrical map" of the motor that allows for tight control of the motor.
