Method and apparatus for controlling swing body of construction equipment

Abstract

Exemplary embodiments relate to controlling a swing body of construction equipment. Disclosed methods may include selecting a representative signal vs. speed curve, receiving an operating signal value from the operating input device, obtaining a reference speed value by applying said operating signal value to the selected curve, transmitting a command for rotational speed equivalent to said reference speed to the swing motor making the swing body rotate, obtaining rotational speed of said motor, determining whether a value obtained by subtracting rotational speed from reference speed exceeds the maximum permissible errors, obtaining a new signal vs. speed curve equivalent to rotational speed when a value obtained by subtracting rotational speed from reference speed exceeds the maximum permissible errors, obtaining a new reference speed value from an operating signal value using said new curve, and transmitting a new command for rotational speed equivalent to said new reference speed to said motor.
