Abstract
A method and apparatus for electronically controlled movement and positioning. The method includes encoding absolute position signals, reading out digital velocity signals from a memory responsive to the absolute position signals in accordance with a velocity-position profile, converting the digital velocity signals to analog signals and scaling the analog signals so that they may be used to drive a motor. The apparatus is a programmable electronic controller which performs the method.
