ABSTRACT:
A self-synchronous AC servo system is used for high-speed serial communication and has multiple axes control. The system includes a computer sending command to master axis drive and slave axis drive through a transmission line. The master axis drive and slave axis drive send interrupt request to the computer through the transmission line after receiving the command. Each drive will judge whether the command is for it self according to the interrupt request and stores a plurality of computer commands in queue. Each drive drives master axis motor or slave axis motor by the queued command synchronously according to a synchronous timing clock.
