PROBLEM TO BE SOLVED: To provide a servo system for shorter response time at the time of a servo driver starts operation, changes speed, or stops operation, a plurality of servo drivers are synchronously controlled. SOLUTION: As a first step, information is transmitted and set to all three servo drivers. For example, an NC controller 21 transmits a coordinate information and speed information required for alignment operation to one by one of the three servo drivers. After the first step, and operation-start command signal is outputted to the three servo drivers by a transmission means 26 from the NC controller 21, and the three servo drivers receive the synchronous signal and carry out it to start driving the three servo motors (a second step).
