Abstract

Advanced digital motion control is a multi-axis incremental position control system which includes a digital processor and memory, servo motor actuator with tachometer feedback, velocity servo power amplifier, position feedback device, position feedback signal converter, and digital to analog converter. The processor provides digital time reference feedback control of motion profiling and positioning of the mechanical load for multi-axis simultaneously without sacrificing update feedback rate control. The read time code execution time is compact and speed efficient optimizing control of multi-axis high speed/high accuracy servo systems in a space and cost effective method.
