The Allen-Bradley/Rockwell Automation 20G1AND186JN0NNNNN drive is a sophisticated variable speed motor controller, equipped with an advanced autotune feature designed to precisely assess and store motor characteristics in non-volatile memory, greatly reducing manual input errors. As part of the PowerFlex 755 series, this drive offers five distinct autotune selections including ready, calculate, static tune, rotate tune, and inertia tune, which collectively allow for comprehensive motor analysis and adjustment. The autotune process includes the static and rotate tune tests for precise configuration, ensuring optimal performance by automatically setting critical parameters such as IR voltage drop, Ixo voltage drop, flux current reference, and slip RPM, while requiring the motor to be uncoupled during rotate tune tests to prevent invalid results in sensorless vector control mode.
