Abstract:
1. A multiple axis servo motor drive control system for providing coordinated three-dimensional position control of a moving object, comprising: a host system for supplying multi-axis servo control commands, wherein said PWM signals define said coordinated three-dimensional position control; a processor coupled to the host system for receiving the multi-axis servo control commands, the processor having a PWM control unit for producing PWM signals on the basis of the servo motor control commands, wherein said PWM signals define said coordinated three-dimensional position control; the PWM control unit comprising a time slice selection unit for generating a plurality of axis selection signals to select components related to a selected axis in the multi-axis control; said PWM control unit being operable to provide multiple sets of PWM signals to thereby supply a respective set of PWM signals to a motor drive for the selected axis; and the respective set of PWM signals produced by the PWM control unit for said selected axis being selected on the basis of said axis selection signals.
