ABSTRACT:
A distributed multi-axis motion control system comprises a multicast communications network having several node components. Each of the node components includes a clock and an actuator. The actuators are part of a motor system and a pattern profile table of the motor system is generated. The pattern profile table is translated into a separate single-direction-of-motion pattern table to separately direct the motion of each of the actuators of the node components. A grandmaster clock generates synchronization signals which are transmitted through the network at a sync interval and which synchronize the clocks. Time-bombs are generated at an interval which is a whole number multiple of the sync interval. The time-bombs cause concurrent execution of the first and subsequent steps from the single-direction-of-motion pattern tables to produce synchronized multi-axis motion of the motor system.
