Auto-Tuning
Auto-Tuning uses motor characteristics to automatically set drive parameters for vector
control. Think about the type of motor, drive control method, and the motor installation
environment and select the best Auto-Tuning method.
WARNING
Injury to Personnel. Rotational Auto-Tuning rotates the motor at 50% or more of the
motor rated frequency. Make sure that there are no issues related to safety in the area around the drive
and motor. Increased motor frequency can cause serious injury or death.
