ABSTRACT:
In a servo system having a controller such as a numeric controller for multi-axes control and a plural number of drive-unit-built-in servo motors, a branching circuit (2) is provided between the controller and the drive-unit-built-in servo motors to communicate through branching of the signals from the branching circuit (2) to the drive-unit-built-in servo motors (3). A constant voltage is output from the drive units and charged on the resistors (14) in the branching circuit (2) with resistance values different from one another in each shaft and the shaft numbers are identified through the detection of the currents flowing out at that time by the drive units in the drive-unit-built-in servo motors (3). The servo system realizes the reduction in wiring, the enhanced reliability and the elimination of hardware settings.
