Step 5: Run the Motor

Make sure the power is OFF, and that it cannot be switched on accidentally whilst you are working.

The Autotune Feature

Note The drive will not perform an Autotune when in Volts/Hz Mode (Open-Loop Drive.) An Autotune is not
necessary in this control mode.
The Autotune feature identifies motor characteristics to allow the drive to control the motor.
It loads the values into the parameters below, which are in the QUICK SETUP menu.
