PURPOSE: A stage setting control system is provided to control driving motors separately one by one with separate motor control modules, thereby realizing improved control speeds compared to a group control by PLC. CONSTITUTION: A stage setting control system comprises: a main console(10) for generating motor control signals according to an administrator's operation to control a driving motor(M) which is a driving unit for a stage setting; and first and second central computers(30,40) for collecting the motor control signals which are input through the main console. During a normal operation, the driving motor is controlled by receiving the motor control signals of a first central computer. When the first central computer operates abnormally, a motor control module(50) controls the driving motor by receiving the motor control signals of the second central computer. The main console comprises: a first touch monitor(12) equipped with a touch screen; and a first console PC(14) for generating the motor control signals to control the driving motor when control signals are input by controlling the first touch monitor.
