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.
