Abstract

PURPOSE:To improve positioning precision with simple constitution by obtaining a speed command variable by a speed pattern generating circuit relating to an acceleration-deceleration run distance based upon a stop point. CONSTITUTION:In an up/down counter 6, an acceleration-deceleration run distance Sv from a stop position is held and used as the address signal of a speed pattern generator 7. In the memory MEM of the pattern generator 7, values for which an equation (where k is a constant and alpha is acceleration) holds are stored for constant acceleration-deceleration control, thereby obtaining a speed command pulse string OUT' which corresponds to the acceleration-deceleration run distance Sv. Under the control of a control means 3', the pulse OUT' is applied to the up or down terminal of the up/down counter 6 through a frequency divider 8 to vary the acceleration-deceleration run distance Sv. The application of the pulse string to the counter terminal is performed only during acceleration or deceleration.
