Abstract
A servo control method is realized by connecting a high-speed serial communication interface with a microcomputer, a dual port memory and an IC for high-speed serial communication mounted thereon to an extended bus of a personal computer and by connecting between the high-speed serial communication interface and a plurality of servo controllers with a serial line in a multi-drop system.
Claims17
A servo control method for executing serial communications between a computer and a plurality of servo controllers, wherein each of said servo controllers provides motion control for a plurality of motors, comprising:
- transferring request information simultaneously to each of said plurality of servo controllers from said computer synchronously with a master clock;
- and
- transferring response information serially from each of said plurality of servo controllers to said computer synchronously with said master clock, wherein said servo controllers concurrently process said request information synchronously with said master clock and said motion control provided by each of said servo controllers is synchronous with said master clock.
A servo control system, comprising:
- a plurality of motors;
- a plurality of servo controllers to provide motion control for said plurality of motors;
- a master clock;
- a computer for transferring request information simultaneously to said plurality of servo controllers synchronously with said master clock, and for transferring response information serially from said plurality of servo controllers synchronously with said master clock.
