Abstract

본 발명은 선회 모터(120)를 구동시키기 위한 작동유를 토출하며, 입력되는 펌프 지령치(Vpump)에 따라 토출 유량 조절이 가능한 유압 펌프(100)와, 상기 유압 펌프(100)로부터 토출되는 작동유의 압력을 감지하는 압력 센서(102)와, 선회 조작부(130)로부터 입력된 선회 조작량(Vsw)을 기준으로 상기 펌프 지령치(Vpump)를 산출하여 상기 유압 펌프(100)로 출력하는 제어부(150)를 포함하는 건설기계의 선회제어장치에 관한 것으로서, 상기 제어부(150)는 상기 입력된 선회 조작량(Vsw)이 기설정된 기준 선회 조작량(Vswo)보다 크고 상기 압력 센서(102)로부터 검출된 상기 유압 펌프(100)의 토출 압력(Ppump)이 제 1 기준 압력(Pswr1)보다 작으면, 상기 기준 선회 조작량(Vswo)으로부터 상기 입력된 선회 조작량(Vsw)까지 점진적으로 증가하는 변환 선회 조작량(Vsw')을 산출하고 상기 변환 선회 조작량(Vsw')에 대응하는 상기 유압 펌프(100)의 펌프 지령치(Vpump)를 산출하는 것을 특징으로 한다.
