PROBLEM TO BE SOLVED: To provide a servo system that easily handles an analog sensor, saves wiring, and is convenient. SOLUTION: In this servo system for connecting a high-order master 1 to a plurality of servo amplifiers 2, 3 and 4 through a network and motor-controlling them, a servo amplifier 2 includes an analog input circuit 2a for inputting an analog signal of an external sensor 8, and a switching means 2c for switching whether the output of the analog input circuit 2a is connected to the servo amplifier 2 side or to the high-order master 1 side. When the output of the analog input circuit 2a is connected to the servo amplifier 2 side by the switching means 2c, the analog signal is used for the motor control. When the output is connected to the high-order master 1 side, the analog signal is used for controlling the whole system. COPYRIGHT: (C)2010,JPO&INPIT
