5.44.3 Auto Change
The auto change function enables the inverter to automatically switch operations between main
and auxiliary motors. Prolonged continuous operation of a motor deteriorates motor capabilities.
The auto change function switches the motors automatically when certain conditions are met to
avoid biased use of certain motors and protect them from deterioration.
