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.
Claims8
A self-synchronous AC servo system for high-speed serial communication, the system used for multiple axes control and comprising:
- a transmission line;
- a computer coupled to the transmission line;
- a master axis drive coupled to the transmission line;
- a master axis motor coupled to the master axis drive;
- a plurality of slave axis drives coupled to the transmission line;
- and
- a plurality of slave axis motor coupled to the slave axis drives;
- wherein the computer sends command to the master axis drive and the slave axis drives through the transmission line, the master axis drive and the slave axis drives sending interrupt request to the computer after receiving command from the computer,
- wherein each drive judging whether or not the command is for itself;
- the drives storing a plurality of commands from the computer in queue;
- the drives driving the master axis motor and the slave axis motors in synchronism by the commands stored in queue according to a synchronous timing clock.
A method for operating a self-synchronous AC servo system for high-speed serial communication, comprising:
- a computer sending command to a master axis drive and a plurality of slave axis drives through a transmission line;
- the master axis drive and the slave axis drives sending interrupt requests to the computer through the transmission line after receiving command;
- the drive judging whether the command is for itself by the interrupt request;
- the drive stores a plurality of commands of computer in queue;
- and
- the drive controls the master axis motor and the slave axis motors by the commands stored in queue and according to a synchronous timing clock.
