Abstract
A positioning apparatus and method for synchronously controlling a plurality of motors, such as servo motors, and exercises synchronous control by means of only motors without using any mechanisms, such as coupling shafts, clutches, gears and cams. A controller has a virtual drive capability which provides a virtual cam and virtual clutch capability on the basis of stored values, permitting continuous and repeated operation of a single cycle of positioning with respect to changes in input axis position address data without recalculation of command addresses in real time.
